The port mode
determines whether a unified port on the fabric interconnect is configured to
carry Ethernet or Fibre Channel traffic. You configure the port mode in Cisco
UCS Manager. However, the fabric interconnect does not automatically discover
the port mode.
Changing the port mode
deletes the existing port configuration and replaces it with a new logical
port. Any objects associated with that port configuration, such as VLANs and
VSANS, are also removed. There is no restriction on the number of times you can
change the port mode for a unified port.
Port Types
The port type defines
the type of traffic carried over a unified port connection.
By default, unified
ports changed to Ethernet port mode are set to the Ethernet uplink port type.
Unified ports changed to Fibre Channel port mode are set to the Fibre Channel
uplink port type. You cannot unconfigure Fibre Channel ports.
Changing the port type
does not require a reboot.
Ethernet Port Mode
When you set the port
mode to Ethernet, you can configure the following port types:
Server ports
Ethernet uplink
ports
Ethernet port
channel members
FCoE ports
Appliance ports
Appliance port
channel members
SPAN destination
ports
SPAN source ports
Note
For SPAN source
ports, configure one of the port types and then configure the port as SPAN
source.
Fibre Channel Port Mode
When you set the port
mode to Fibre Channel, you can configure the following port types:
Fibre Channel
uplink ports
Fibre Channel port channel members
Fibre Channel
storage ports
SPAN source ports
Note
For SPAN source
ports, configure one of the port types and then configure the port as SPAN
source.

Step 7
Click OK to save your port-mode configuration.
The fabric interconnect reboots. All data traffic through that fabric interconnect is interrupted. If this occurs in a cluster
configuration that provides high availability and includes servers with vNICs that are configured for failover, traffic fails
over to the other fabric interconnect and no interruption occurs.
What to do next
Configure the port types for the ports. You can right-click on any port in the module display above the slider and configure
that port for an available port type.
Cisco UCS 6536 Fabric Interconnects
Port Breakout Functionality on Cisco UCS 6536 Fabric Interconnects
The Cisco UCS 6536 36-Port Fabric Interconnect is a One-Rack-Unit (1RU) 1/10/25/40/100 Gigabit Ethernet, FCoE, and Fibre Channel
switch offering up to 7.42 Tbps throughput and up to 36 ports.
Cisco UCS 6536 Fabric Interconnect supports splitting a single 40 Gigabit(G)/100G Quad Small Form-factor Pluggable (QSFP)
port into four 10G/25G ports using a supported breakout cable. The switch has 32 40/100-Gbps Ethernet ports and four unified
ports that can support 40/100-Gbps Ethernet ports or 16 Fiber Channel (FC) ports after breakout at 8/16/32-Gbps FC speeds.
The 16 FC ports after breakout can operate as an FC Uplink or FC storage port. The switch also supports two ports (Port 9
and Port 10) at 1-Gbps speed using QSA, and all 36 ports can breakout for 10 or 25 Gbps Ethernet connectivity. All Ethernet
ports can support FCoE.
Port breakout is supported for Ethernet ports (1-32) and Unified ports (33-36). These 40/100G ports are numbered in a 2-tuple
naming convention. The process of changing the configuration from 40G to 10G, or from 100G to 25G is called breakout, and
the process of changing the configuration from [4X]10G to 40G or from [4X]25G to 100G is called unconfigure.
When you break out a 40G port into 10G ports or a 100G port into 25G ports, the resulting ports are numbered using a 3-tuple
naming convention. For example, the breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/31/1, 1/31/2,
1/31/3, and 1/31/4.
FC breakout is supported on ports 36 through 33 when each port is configured with a four-port breakout cable. For example:
Four FC breakout ports on the physical port 33 are numbered as 1/33/1, 1/33/2, 1/33/3, and 1/33/4.
Note
Fibre Channel support is only available through the configuration of the Unified Ports (36-33) as Fibre Channel breakout port.

Configuring a 10/25G Port with QSA on Cisco UCS FI 6536
When a port on UCS FI 6536 is operating at the default 40/100G port speed, Cisco UCS Manager does not let you choose port
speeds of 1G, 10G, or 25G. To use a 40/100G port on UCS FI 6536 as a 10/25 G port with a QSFP+Adapter (QSA) transceiver on
the other end, you must configure it in the breakout mode.
Note
When you try to change port speeds to 10G or 25G, Cisco UCS Manager displays a prompt to configure the port in breakout mode.
After you configure a breakout port, you can configure each 10/25G GB sub-port as an uplink, or FCoE uplink port as required.
When you break out the port, use a breakout cable to split a single port into four 10G or 25G ports, and configure the ports
in breakout mode, you can use all lanes as 10 G or 25G ports. If you break out the port without a breakout cable, only the
first lane becomes usable as a 10G or 25G interface.
Procedure
Step 1
Configure breakout feature on the port that you want to use as a 10/25G port on the Cisco UCS FI 64108. For more information
about configuring the break out feature, see Configuring Fabric Interconnect Ethernet Breakout Ports.
Step 2
In Cisco UCS Manager, the first tuple interface is enabled after the QSA transceiver is plugged into the FI port. You can
configure this interface based on your requirements.
The resulting ports after a break out of the 40/100G port are numbered using a 3-tuple naming convention. For example, the
breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/36/1, 1/36/2, 1/36/3, 1/36/4, and only the first port
becomes usable as a 10 GB port.
Cisco UCS 6400 Series Fabric Interconnects
Port Breakout Functionality on Cisco UCS 64108 Fabric Interconnects
About Breakout Ports
Cisco UCS 64108 fabric interconnects support splitting a single 40/100G QSFP port into four 10/25G ports using a supported
breakout cable. On the UCS 64108 fabric interconnect, by default, there are 12 ports in the 40/100G mode. These are ports
97 to 108. These 40/100G ports are numbered in a 2-tuple naming convention. For example, the second 40G port is numbered as
1/99. The process of changing the configuration from 40G to 10 G, or from 100G to 25G is called breakout, and the process
of changing the configuration from [4X]10G to 40G or from [4X]25G to 100G is called unconfigure. These ports can be used as
uplink port, appliance port, server port (using FEX), and FCoE storage port.
When you break out a 40G port into 10G ports or a 100G port into 25G ports, the resulting ports are numbered using a 3-tuple
naming convention. For example, the breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/99/1, 1/99/2,
1/99/3, 1/99/4.
Note
Cisco UCS Manager does not support connection of FEX, chassis, blade, IOM, or adapters (other than VIC adapters) to the uplink ports of Fabric
Interconnect.
Starting with Cisco UCS Manager Release 4.2(3b), configuring the Ethernet breakout ports will not lead to Fabric Interconnect reboot.

Configuring a 10/25G Port with QSA on Cisco UCS FI 64108
When a port on UCS FI 64108 is operating at the default 40/100G port speed, Cisco UCS Manager does not let you choose port
speeds of 1G, 10G, or 25G. To use a 40/100G port on UCS FI 6454 as a 10/25 G port with a QSFP+Adapter (QSA) transceiver on
the other end, you must configure it in the breakout mode.
Note
When you try to change port speeds to 10G or 25G, Cisco UCS Manager displays a prompt to configure the port in breakout mode.
After you configure a breakout port, you can configure each 10/25G GB sub-port as an uplink, or FCoE uplink port as required.
When you break out the port, use a breakout cable to split a single port into four 10G or 25G ports, and configure the ports
in breakout mode, you can use all lanes as 10 G or 25G ports. If you break out the port without a breakout cable, only the
first lane becomes usable as a 10G or 25G interface.
Procedure
Step 1
Configure breakout feature on the port that you want to use as a 10/25G port on the Cisco UCS FI 64108. For more information
about configuring the break out feature, see Configuring Fabric Interconnect Ethernet Breakout Ports.
Step 2
In Cisco UCS Manager, the first tuple interface is enabled after the QSA transceiver is plugged into the FI port. You can
configure this interface based on your requirements.
The resulting ports after a break out of the 40/100G port are numbered using a 3-tuple naming convention. For example, the
breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/50/1, 1/50/2, 1/50/3, 1/50/4, and only the first port
becomes usable as a 10 GB port.
Port Breakout Functionality on Cisco UCS 6454 Fabric Interconnects
About Breakout Ports
Cisco UCS 6454 fabric interconnects support splitting a single 40/100G QSFP port into four 10/25G ports using a supported
breakout cable. These ports can be used only as uplink ports connecting to a 10/25G switch. On the UCS 6454 fabric interconnect,
by default, there are 6 ports in the 40/100G mode. These are ports 49 to 54. These 40/100G ports are numbered in a 2-tuple
naming convention. For example, the second 40G port is numbered as 1/50. The process of changing the configuration from 40G
to 10 G, or from 100G to 25G is called breakout, and the process of changing the configuration from [4X]10G to 40G or from
[4X]25G to 100G is called unconfigure.
When you break out a 40G port into 10G ports or a 100G port into 25G ports, the resulting ports are numbered using a 3-tuple
naming convention. For example, the breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/50/1, 1/50/2,
1/50/3, 1/50/4.
Starting with Cisco UCS Manager Release 4.2(3b), Ethernet breakout ports configuration will not lead to Fabric Interconnect reboot.
Starting with Cisco UCS Manager Release 4.1(3a), you can connect Cisco UCS Rack servers with VIC 1455 and 1457 adapters, to the uplink ports 49 to 54 (40/100
Gbps Ethernet or FCoE) in Cisco UCS 6454 Fabric Interconnects.
Note
Cisco UCS Manager does not support connection of FEX, chassis, blade, IOM, or adapters (other than VIC 1455 and 1457 adapters) to the uplink
ports of Fabric Interconnect.
The following image shows the rear view of the Cisco UCS 6454 fabric interconnect, and includes the ports that support breakout
port functionality:
1
Ports 1-16 (Unified Ports 10/25 Gbps Ethernet or FCoE or 8/16/32 Gbps Fibre Channel)
2
Ports 17-44 (10/25 Gbps Ethernet or FCoE)
3
Ports 45-48 (1/10/25 Gbps Ethernet or FCoE)
4
Uplink Ports 49-54 (40/100 Gbps Ethernet or FCoE)
Breakout Port Guidelines
The following are the guidelines for breakout functionality for Cisco UCS 6454 fabric interconnects:
The breakout configurable ports are ports 49-54.
You cannot configure the speed for each breakout port. Each breakout port is in auto mode.
In Cisco UCS Manager Release 4.0(2), breakout ports are not supported as destinations for traffic monitoring.
Ports 49-54 at 40/100G can be configured as uplink, FCoE, or appliance port. Ports 49-54 after breakout to 10/25G can be configured
as uplink, appliance, FCoE, or for direct-connect rack server connectivity.

Configuring a 10/25G Port with QSA Adapter on Cisco UCS FI 6454
When a port on UCS FI 6454 is operating at the default 40/100G port speed, Cisco UCS Manager does not let you choose port
speeds of 1G, 10G, or 25G. To use a 40/100G port on UCS FI 6454 as a 10/25 G port with a QSFP+Adapter (QSA) transceiver on
the other end, you must configure it in the breakout mode.
Note
When you try to change port speeds to 10G or 25G, Cisco UCS Manager displays a prompt to configure the port in breakout mode.
After you configure a breakout port, you can configure each 10/25G GB sub-port as an uplink, or FCoE uplink port as required.
When you break out the port, use a breakout cable to split a single port into four 10G or 25G ports, and configure the ports
in breakout mode, you can use all lanes as 10 G or 25G ports. If you break out the port without a breakout cable, only the
first lane becomes usable as a 10G or 25G interface.
Procedure
Step 1
Configure breakout feature on the port that you want to use as a 10/25G port on the Cisco UCS FI 6454. For more information
about configuring the break out feature, see Configuring Fabric Interconnect Ethernet Breakout Ports.
Step 2
In Cisco UCS Manager, the first tuple interface is enabled after the QSA transceiver is plugged into the FI port. You can
configure this interface based on your requirements.
The resulting ports after a break out of the 40/100G port are numbered using a 3-tuple naming convention. For example, the
breakout ports of the second 40-Gigabit Ethernet port are numbered as 1/50/1, 1/50/2, 1/50/3, 1/50/4, and only the first port
becomes usable as a 10 GB port.

Port Breakout
Functionality on Cisco UCS 6300 Series Fabric Interconnects
About Breakout
Ports
Cisco UCS fabric
interconnect 6300 series supports splitting a single QSFP port into four 10G
ports using a supported breakout cable. By default, there are 32 ports in the
40G mode. These 40G ports are numbered in a 2-tuple naming convention. For
example, the second 40G port is numbered as 1/2. The process of changing the
configuration from 40G to 10G is called breakout and the process of changing
the configuration from [4X]10G to 40G is called unconfigure.
When you break out a
40G port into 10G ports, the resulting ports are numbered using a 3-tuple

Configuring a 10G Port with QSA Adapter on Cisco UCS FI 6332 and 6332-16UP
When a port on UCS FI 6332 or 6332-16UP is operating at the default 40G port speed, Cisco UCS Manager does not let you choose
port speeds of 1GB or 10GB. To use a 40G port on UCS FI 6332 or 6332-16UP as a 10 GB port with a QSFP+Adapter (QSA) transceiver
on the other end, you must configure it in the breakout mode.
Note
When you try to change port speeds to 1GB or 10GB, Cisco UCS Manager displays a prompt to configure the port in breakout mode.
Once you configure a breakout port, you can configure each 10GB sub-port as server, uplink, FCoE uplink, FCoE storage or appliance
as required.
When you break out the port, only the first lane becomes usable as a
10G interface. If you use a breakout cable to split a single port into four 10G
ports, and configure the ports in breakout mode, you can use all lanes as 10 GB
ports.
Procedure
Step 1
Configure breakout feature on the port that you want to use as a 10GB port on the Cisco UCS FI 6332 or 6332-16UP. For more
information about configuring the break out feature, see Configuring Fabric Interconnect Ethernet Breakout Ports.
Caution
Configuring breakout ports requires rebooting the Fabric Interconnect. Any existing configuration on a port is erased. It
is recommended to break out all required ports in a single transaction.
Step 2
In Cisco UCS Manager, the first tuple interface is enabled after
the QSA transceiver is plugged into the FI port. You can configure this
interface based on your requirements.
The resulting ports after a break out of the 40G port are numbered
using a 3-tuple naming convention. For example, the supported breakout ports
are numbered Br-Ethernet 1/25/1, Br-Ethernet 1/25/2, Br-Ethernet 1/25/3, and
Br-Ethernet 1/25/4, and only the first port becomes usable as a 10 GB port.
Reconfiguring an Ethernet Breakout Port
You can reconfigure an unconfigured breakout port in a particular role, such as Server, Uplink, or Appliance. Reconfiguring
a Cisco UCS 6300, 6400, or 6500 Series Fabric Interconnect breakout port allows you to modify the existing port configuration to your current requirements.
An unconfigured Cisco UCS 6400 Series Fabric Interconnect breakout port can be reconfigured only as an Uplink or FCoE Uplink
port.

Unified Ports
Beacon LEDs for
Unified Ports
Each port fabric interconnect has a corresponding beacon LED. When the Beacon LED property is configured, the beacon LEDs illuminate, showing you which ports are configured in a given port mode.
You can configure the
Beacon LED property to show you which ports are
grouped in one port mode: either Ethernet or Fibre Channel. By default, the
Beacon LED property is set to Off.
Note
For unified ports on
the expansion module, you can reset the
Beacon LED property to the default value of
Off during expansion module reboot.
Guidelines for
Configuring Unified Ports
Consider the following
guidelines and restrictions when configuring unified ports:
Hardware and Software Requirements
Unified ports are supported on the following:
Cisco UCS Fabric Interconnects 9108 100G (Cisco UCS X-Series Direct ) with Cisco UCS Manager Release 4.3(4b) and later releases
Cisco UCS 6536 Fabric Interconnect with Cisco UCS Manager Release 4.2(3b) and later releases
Cisco UCS 64108 Fabric Interconnect with Cisco UCS Manager Release 4.1 and later releases
Cisco UCS 6454 Fabric Interconnect with Cisco UCS Manager Release 4.0 and later releases
UCS 6300 Series Fabric Interconnects with Cisco UCS Manager Release 3.1 and later releases
UCS 6324 Fabric Interconnects with Cisco UCS Manager Release 3.0 and later releases
Port Mode
Placement
Because the
Cisco UCS Manager GUI
interface uses a slider to configure the port mode for unified ports
on a fixed or expansion module,
it automatically enforces the following restrictions which limits how port
modes can be assigned to unified ports. When using the
Cisco UCS Manager CLI interface, these restrictions are enforced when you commit the
transaction to the system configuration. If the port mode configuration
violates any of the following restrictions, the
Cisco UCS Manager CLI displays an error:
Ethernet ports
must be grouped together in a block.
For
each module (fixed or expansion), the Ethernet port block must start with the
first port and end with an even numbered port.
Fibre Channel
ports must be grouped together in a block.
For
each module (fixed or expansion), the first port in the Fibre Channel port
block must follow the last Ethernet port and extend to include the rest of the
ports in the module. For configurations that include only Fibre Channel ports,
the Fibre Channel block must start with the first port on the fixed or
expansion module.
Note
On the Cisco UCS Fabric Interconnects 9108 100G, the ports 1 & 2 are unified ports and can be configured as Ethernet or Fibre Channel ports.
On the Cisco UCS 6536 Fabric Interconnect, the Unified Port capability is restricted to the first 16 ports. Only ports 1/1-1/16 can be configured as FC. The Fibre
Channel ports must be contiguous, followed by contiguous Ethernet ports.
On the Cisco UCS 6400 Series Fabric Interconnect, the Unified Port capability is restricted to first 16 ports. Only ports 1/1-1/16 can be configured as FC. The Fibre Channel
ports must be contiguous, followed by contiguous Ethernet ports. The Cisco UCS 6400 Series Fabric Interconnect connected to a Cisco UCS server, connecting more than 16 ports will result in an error.
Alternating Ethernet and Fibre Channel ports is not supported
on a single module.
Example of a valid configuration— Might include unified
ports 1–16 on the fixed module configured in Ethernet port mode and ports 17–32
in Fibre Channel port mode. On the expansion module you could configure ports
1–4 in Ethernet port mode and then configure ports 5–16 in Fibre Channel mode.
The rule about alternating Ethernet and Fibre Channel port types is not
violated because this port arrangement complies with the rules on each
individual module.
Example of an invalid configuration— Might include a block
of Fibre Channel ports starting with port 16. Because each block of ports has
to start with an odd-numbered port, you would have to start the block with port
17.
Note
The total number of uplink Ethernet ports and uplink Ethernet port channel members that can be configured on each fabric interconnect
is limited to 31. This limitation includes uplink Ethernet ports and uplink Ethernet port channel members configured on the
expansion module.
Cautions and
Guidelines for Configuring Unified Uplink Ports and Unified Storage
Ports
The following are
cautions and guidelines to follow while working with unified uplink ports and
unified storage ports:
In an unified
uplink port, if you enable one component as a SPAN source, the other component
will automatically become a SPAN source.
Note
If you create or
delete a SPAN source under the Ethernet uplink port,
Cisco UCS Manager
automatically creates or deletes a SPAN source under the FCoE uplink port. The
same happens when you create a SPAN source on the FCOE uplink port.
You must configure
a non default native VLAN on FCoE and unified uplink ports. This VLAN is not
used for any traffic.
Cisco UCS Manager will reuse
an existing fcoe-storage-native-vlan for this purpose. This
fcoe-storage-native-vlan will be used as a native VLAN on FCoE and unified
uplinks.
In an unified
uplink port, if you do not specify a non default VLAN for the Ethernet uplink
port the fcoe-storage-native-vlan will be assigned as the native VLAN on the
unified uplink port. If the Ethernet port has a non default native VLAN
specified as native VLAN, this will be assigned as the native VLAN for unified
uplink port.
When you create or
delete a member port under an Ethernet port channel,
Cisco UCS Manager
automatically creates or deletes the member port under FCoE port channel. The
same happens when you create or delete a member port in FCoE port channel.
When you configure
an Ethernet port as a standalone port, such as server port, Ethernet uplink,
FCoE uplink or FCoE storage and make it as a member port for an Ethernet or
FCOE port channel,
Cisco UCS Manager
automatically makes this port as a member of both Ethernet and FCoE port
channels.
When you remove
the membership for a member port from being a member of server uplink, Ethernet
uplink, FCoE uplink or FCoE storage,
Cisco UCS Manager deletes the
corresponding members ports from Ethernet port channel and FCoE port channel
and creates a new standalone port.
If you downgrade
Cisco UCS Manager from release
2.1 to any of the prior releases, all unified uplink ports and port channels
will be converted to Ethernet ports and Ethernet port channels when the
downgrade is complete. Similarly, all the unified storage ports will be
converted to appliance ports.
For unified uplink
ports and unified storage ports, when you create two interfaces, only one
license is checked out. As long as either interface is enabled, the license
remains checked out. The license will be released only if both the interfaces
are disabled for a unified uplink port or a unified storage port.
In Cisco UCS 6536 Fabric Interconnect to configure FC breakout port, you have to configure ports from the sequence from 1/36 through 1/33. FC breakout ports (36
- 33) cannot be configured unless the previous ports are FC breakout ports. Also, configuring a single (individual) FC breakout
port is supported.
Ports 33-36 can be configured only as FC Uplink Port or FC Storage Port when it is configured as unified port.
The Cisco UCS Fabric Interconnects 9108 100G (Cisco UCS X-Series Direct) supports port breakout for Ethernet Ports (1-8) and Unified Ports (1 and 2). These unified ports can function as Ethernet
or Fibre Channel (FC) ports, accommodating up to 8 sub-ports configured in groups of four. The FC breakout ports can be configured
as FC Uplink Port or FC Storage Port.
Configuring the Beacon LEDs for Unified Ports
Complete the following task for each module for which you want
to configure beacon LEDs.
Depending upon the location of the unified ports for which you want to configure the beacon LEDs, click on one of the following:
Fixed Module
Expansion Module
Step 4
In the
Work pane, click the
General tab.
Step 5
In the Properties area, click one of the following radio buttons in the Beacon LED field:
Off—All physical LEDs are off.
Eth—The physical LEDs next to all Ethernet ports are on.
Fc—The physical LEDs next to all Fibre Channel ports are on.
Step 6
Click Save Changes.
Changing Port Modes
Effect of Port Mode
Changes on Data Traffic
Port mode changes can cause an interruption to the data traffic
for the
Cisco UCS domain. The length
of the interruption and the traffic that is affected depend upon the
configuration of the
Cisco UCS domain and the
module on which you made the port mode changes.
Tip
To minimize the
traffic disruption during system changes, form a Fibre Channel uplink
port-channel across the fixed and expansion modules.
Impact of Port
Mode Changes on an Expansion Module
After you make port
mode changes on an expansion module, the module reboots. All traffic through
ports on the expansion module is interrupted for approximately one minute while
the module reboots.
Impact of Port
Mode Changes on the Fixed Module in a Cluster Configuration
A cluster
configuration has two fabric interconnects. After you make port changes to the
fixed module, the fabric interconnect reboots. The impact on the data traffic
depends upon whether or not you have configured the server vNICs to failover to
the other fabric interconnect when one fails.
If you change the port
modes on the expansion module of one fabric interconnect and then wait for that
to reboot before changing the port modes on the second fabric interconnect, the
following occurs:
With server vNIC
failover, traffic fails over to the other fabric interconnect and no
interruption occurs.
Without server
vNIC failover, all data traffic through the fabric interconnect on which you
changed the port modes is interrupted for approximately eight minutes while the
fabric interconnect reboots.
If you change the
port modes on the fixed modules of both fabric interconnects simultaneously,
all data traffic through the fabric interconnects are interrupted for
approximately eight minutes while the fabric interconnects reboot.
Impact of Port Mode Changes on the Fixed Module in a
Non-Cluster Configuration
A non-cluster configuration has only one fabric interconnect. After you make port changes to the fixed module, the fabric interconnect
reboots. All data traffic through the fabric interconnect is interrupted for approximately eight minutes while the fabric
interconnect reboots.
Configuring Port Modes for Cisco UCS X-Series Direct Fabric Interconnect
In Cisco UCS X-Series Direct Fabric Interconnects, port breakout is supported for Ethernet Ports (1-8) and Unified Ports (1-2). The unified ports can
be configured as FC uplink ports (with sub-group of 4 in each unified port, a maximum 16 sub-ports can be configured as FC
port).
Caution
Changing the port mode can cause an interruption in data traffic and lead to immediate Fabric Interconnect reboot.
If the Cisco UCS domain has a cluster configuration that is set up for high availability and servers with service profiles
that are configured for failover, traffic fails over to the other fabric interconnect and data traffic is not interrupted
when the port mode is changed on the fixed module.
In the Actions area of the General tab, click Configure Unified Ports.
Step 5
Review the confirmation message and click one of the following:
Yes—To continue with configuring the port mode.

Server Ports
Automatic Configuration of Fabric Interconnect Server Ports
Starting with Cisco UCS Manager release 3.1(3), you can automatically configure the fabric interconnect server ports. The server Port Auto-Discovery Policy determines how the system reacts when a new rack server, chassis, or FEX is added. By enabling this policy, Cisco UCS Manager automatically determines the type of device connected to the switch port and configures the switch port accordingly.
Note
If you do not want a Cisco UCS C-Series appliance to be UCS Managed, pre-configure the appliance ports before connecting VIC ports to the Cisco UCS Fabric Interconnects.
The Port Auto-Discovery Policy is not applicable for servers connected through direct 25G port or 4x25g breakout on Cisco UCS 6454, UCS 64108, and 6536 Fabric Interconnects.
The Port Auto-Discovery Policy is not supported on Cisco UCS 6324 Fabric Interconnects.

Q-in-Q Forwarding
QinQ is defined by IEEE 802.1ad. QinQ is also known as 802.1Q-in-802.1Q that helps to expand the VLAN space through the addition
of 802.1Q tag to 802.1Q-tagged packets. This expansion is also termed as VLAN stacking or double VLAN.
In general, the QinQ packets have a standard format. In a VLAN stacking, one 802.11Q tagged packet is encapsulated in another
802.1Q tag. During transmission, packets are forwarded on the outer VLAN tag on the public network and on the inner VLAN tag
for private network.
Note
The 802.1Q supports 4096 VLANs.
Configuring Q-in-Q Forwarding
You can configure Q-in-Q Forwarding on Cisco UCS 6400 Series Fabric Interconnects, Cisco UCS 6536 Fabric Interconnect, and Cisco UCS Fabric Interconnects 9108 100G.

Appliance
Ports
Appliance ports are
only used to connect fabric interconnects to directly attached NFS storage.
Note
When you create a
new appliance VLAN, its IEEE VLAN ID is not added to the LAN Cloud. Therefore,
appliance ports that are configured with the new VLAN remain down, by default,
due to a pinning failure. To bring up these appliance ports, you have to
configure a VLAN in the LAN Cloud with the same IEEE VLAN ID.
Cisco UCS Manager
supports up to four appliance ports per fabric interconnect.
Configuring an
Appliance Port
You can configure
Appliance ports on either the fixed module or an expansion module.
This task describes

Example
The following example shows how to enable forward error correction cl74 on an interface for FCoE uplink 35 on slot 1 of fabric
A, and commits the transaction:
FCoE uplink ports are
physical Ethernet interfaces between the fabric interconnects and the upstream
Ethernet switch, used for carrying FCoE traffic. With this support the same
physical Ethernet port can carry both Ethernet traffic and Fibre Channel
traffic.
FCoE uplink ports
connect to upstream Ethernet switches using the FCoE protocol for Fibre Channel
traffic. This allows both the Fibre Channel traffic and Ethernet traffic to
flow on the same physical Ethernet link.
Note
FCoE uplinks and
unified uplinks enable the multi-hop FCoE feature, by extending the unified
fabric up to the distribution layer switch.
You can configure the
same Ethernet port as any of the following:
FCoE uplink port—As an
FCoE uplink port for only Fibre Channel traffic.
Uplink port—As an
Ethernet port for only Ethernet traffic.
Unified uplink port—As a
unified uplink port to carry both Ethernet and Fibre Channel traffic.
Configuring FCoE
Uplink Ports
You can configure an
FCoE Uplink port on either a fixed module or an expansion module.

Unified Storage
Ports
Unified storage involves configuring the same physical port as both an Ethernet storage interface and an FCoE storage interface.
You can configure any appliance port or FCoE storage port as a unified storage port. To configure a unified storage port,
you must have the fabric interconnect in Fibre Channel switching mode.
In a unified storage port, you can enable or disable individual FCoE storage or appliance interfaces.
In an unified storage port, if you do not specify a non-default VLAN for the appliance port, the FCoE-storage-native-vlan
will be assigned as the native VLAN on the unified storage port. If the appliance port has a non-default native VLAN specified
as native VLAN, this will be assigned as the native VLAN for the unified storage port.
When you enable or disable the appliance interface, the corresponding physical port is enabled or disabled. So when you disable
the appliance interface in unified storage, even if the FCoE storage is enabled, it goes down with the physical port.
When you enable or disable the FCoE storage interface, the corresponding VFC is enabled or disabled. So when the FCoE storage
interface is disabled in a unified storage port, the appliance interface will continue to function normally.
Configuring an
Appliance Port as a Unified Storage Port
You can configure a
unified storage port either from an appliance port or from an FCoE storage
port. You can also configure the unified storage port from an unconfigured
port. If you start from an unconfigured port, you will assign either an
appliance configuration or an FCoE storage configuration to the port, and then
will add another configuration to enable it as a unified storage port.
Important
Make sure the
fabric interconnect is in Fibre Channel switching mode.
Depending on the
location of the ports you want to configure, expand one of the following:

called a unified uplink port. You can individually enable or disable either the
FCoE or Ethernet interfaces independently.
Enabling or
disabling the FCoE uplink results in the corresponding VFC being enabled or
disabled.
Enabling or
disabling an Ethernet uplink results in the corresponding physical port being
enabled or disabled.
If you disable an
Ethernet uplink, it disables the underlying physical port in a unified uplink.
Therefore, even when the FCoE uplink is enabled, the FCoE uplink also goes
down. But if you disable an FCoE uplink, only the VFC goes down. If the
Ethernet uplink is enabled, it can still function properly in the unified
uplink port.
Configuring Unified
Uplink Ports
You can configure
the unified uplink port from either of the following:
From an existing
FCoE uplink port or Ethernet uplink port
From an

Uplink Ethernet Port
Channels
An uplink Ethernet
port channel allows you to group several physical uplink Ethernet ports (link
aggregation) to create one logical Ethernet link to provide fault-tolerance and
high-speed connectivity. In
Cisco UCS Manager, you create a port channel first and then add uplink Ethernet ports
to the port channel. You can add up to 16 uplink Ethernet ports to a port
channel.
Important
The state of a
configured port changes to unconfigured in the following scenarios:
The port is
deleted or removed from a port channel. The port channel can be of any type,
such as, uplink or storage.
A port channel
is deleted.
Note
Cisco UCS uses Link Aggregation Control Protocol (LACP), not Port
Aggregation Protocol (PAgP), to group the uplink Ethernet ports into a port
channel. If the ports on the upstream switch are not configured for LACP, the
fabric interconnects treat all ports in an uplink Ethernet port channel as
individual ports, and therefore forward packets.

Cisco UCS Mini Scalability Ports
The
Cisco UCS 6324 Fabric
Interconnect contains a scalability port as well as four unified ports. The
scalability port is a 40GB QSFP+ breakout port that, with proper cabling, can
support four 1G or 10G SFP+ ports. A scalability port can be used as a licensed
server port for supported
Cisco UCS rack servers, as an appliance port, or as an FCoE port.

Policy-Based Port
Error Handling
If
Cisco UCS Manager
detects any errors on active network interface (NI) ports, and if the
error-disable feature has been implemented,
Cisco UCS Manager
automatically disables the respective fabric interconnect port that is
connected to the NI port that had errors. When a fabric interconnect port is
error disabled, it is effectively shut down and no traffic is sent or received
on that port.
The error-disable
function serves two purposes:
It lets you know
which fabric interconnect port is error-disabled and that the connected NI Port
has errors.
It eliminates the
possibility that this port can cause the failure of other ports other ports
connected to the same Chassis/FEX. Such a failure can occur when the NI port
has errors, which can ultimately cause serious network issues. The
error-disable function helps prevent these situations.

FCoE Port
Channels
An FCoE port channel allows you to group several physical FCoE ports to create one logical FCoE port channel. At a physical
level, the FCoE port channel carries FCoE traffic over an Ethernet port channel. So an FCoE port channel with a set of members
is essentially an Ethernet port channel with the same members. This Ethernet port channel is used as a physical transport
for FCoE traffic.
For each FCoE port
channel,
Cisco UCS Manager creates a VFC internally and binds it to an Ethernet port channel.
FCoE traffic received from the hosts is sent over the VFC the same way as the
FCoE traffic is sent over Fibre Channel uplinks.
Creating an FCoE
Port Channel

Step 4
If a
confirmation dialog box displays, click

Unified Uplink Port
Channel
When you create an
Ethernet port channel and an FCoE port channel with the same ID, it is called a
unified uplink port channel. When the unified port channel is created, a
physical Ethernet port channel and a VFC are created on the fabric interconnect
with the specified members. The physical Ethernet port channel is used to carry
both Ethernet and FCoE traffic. The VFC binds FCoE traffic to the Ethernet port
channel.
The following rules
will apply to the member port sets of the unified uplink port channel:
The Ethernet port
channel and FCoE port channel on the same ID, must have the same set of member
ports.
When you add a
member port channel to the Ethernet port channel,
Cisco UCS Manager adds the same port channel to FCoE port channel as well.
Similarly, adding a member to the FCoE port channel adds the member port to the
Ethernet port channel.
When you delete a
member port from one of the port channels,
Cisco UCS Manager automatically deletes the member port from the other port channel.
If you disable an
Ethernet uplink port channel, it disables the underlying physical port channel
in a unified uplink port channel. Therefore, even when the FCoE uplink is
enabled, the FCoE uplink port channel also goes down. If you disable an FCoE
uplink port channel, only the VFC goes down. If the Ethernet uplink port
channel is enabled, it can still function properly in the unified uplink port
channel.
Adapter Port
Channels
An adapter port
channel groups into one logical link all the physical links going from a Cisco
UCS Virtual Interface Card (VIC) into an
I/O.
Adapter port channels
are created and managed internally by
Cisco UCS Manager when it detects that the correct hardware is present. Adapter
port channels cannot be configured manually. Adapter port channels are viewable
using the
Cisco UCS Manager GUI or the
Cisco UCS Manager CLI.
Viewing Adapter Port Channels
Procedure
Step 1
In the
Navigation pane, click
Equipment.
Step 2
On the Equipment tab, expand Equipment > Chassis > Chassis_Number > Servers > Server_Number > Interface Cards
Step 3
Click the adapter for which you want to view the adapter port channels.
Step 4
In the Work pane, click the DCE Interfaces tab.
Step 5
To view details of the adapter port channel, click the link in the Port Channel column.
Fabric Port Channels
Fabric port channels allow you to group several of the physical links from an IOM and IFM (IOM for Cisco UCS X-Series Servers) to a fabric interconnect into one logical link for redundancy and bandwidth sharing. As long as one link in the fabric port
channel remains active, the fabric port channel continues to operate.
If the correct hardware is connected, fabric port channels are created by Cisco UCS Manager in the following ways:
During chassis discovery according to the settings configured in the chassis discovery policy.
After chassis discovery according to the settings configured in the chassis connectivity policy for a specific chassis.
For each IOM and IFM (IOM for Cisco UCS X-Series Servers) there is a single fabric port channel. Each uplink connecting an IOM and IFM (IOM for Cisco UCS X-Series Servers) to a fabric interconnect can be configured as a discrete link or included in the port channel, but an uplink cannot belong
to more than one fabric port channel. For example, if a chassis with two IOMs is discovered and the chassis discovery policy
is configured to create fabric port channels, Cisco UCS Manager creates two separate fabric port channels: one for the uplinks connecting IOM-1 and another for the uplinks connecting IOM-2.
No other chassis can join these fabric port channels. Similarly, uplinks belonging to the fabric port channel for IOM-1 cannot
join the fabric port channel for IOM-2.
Load Balancing Over
Ports
Load balancing traffic
among ports between IOMs and fabric interconnects uses the following criteria
for hashing.
For Ethernet
traffic:
Layer 2 source and
destination address
Layer 3 source and
destination address
Layer 4 source and
destination ports
For FCoE traffic:
Layer 2 source and
destination address
Source and
destination IDs (SID and DID) and Originator Exchange ID (OXID)
In
this example, a 2200 Series IOM module is verified by connecting iom
X (where
X is the chassis number).
To include all
links from the IOM to the fabric interconnect in a fabric port channel during
chassis discovery, set the link grouping preference in the chassis discovery
policy to port channel.
See the Configuring the Chassis/FEX Discovery Policy section in Cisco UCS Manager Infrastructure Management Guide, Release 3.2.
Step 2
To include
links from an individual chassis in a fabric port channel during chassis
discovery, set the link grouping preference in the chassis connectivity policy
to port channel.
See the Configuring a Chassis Connectivity Policy section in Cisco UCS Manager Infrastructure Management Guide, Release 3.2.
Step 3
After chassis
discovery, enable or disable additional fabric port channel member ports.
To add or remove
chassis links from a fabric port channel after making a change to the chassis
discovery policy or the chassis connectivity policy, reacknowledge the chassis.
Chassis reacknowledgement is not required to enable or disable chassis member
ports from a fabric port channel.
