Unified Ports on the Cisco UCS 6200 Series and 6324 Fabric Interconnects
Unified ports are ports on the Cisco UCS 6200 Series and 6324 Fabric Interconnects that you can configure to carry either Ethernet or Fibre Channel traffic. ACisco UCS domain cannot use these un-reserved ports until you configure them.
Note |
When you configure a port on a fabric interconnect, the administrative state is automatically set to enabled. If the port is connected to another device, this may cause traffic disruption. You can disable the port after configuring it. Configurable beacon LEDs indicate which unified ports are configured for the selected port mode. |
Port Modes
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
-
FCoE Uplink ports
-
SPAN source ports
Note
For SPAN source ports, configure one of the port types and then configure the port as SPAN source.
Data Traffic Interruption from Port Mode Changing
Port mode changes can cause an interruption to the data traffic for the Cisco UCS domain. The length of the interruption and the affected traffic depend upon the configuration of the Cisco UCS domain and the module on which you made the port mode changes.
Tip |
To minimize traffic disruption during system changes, form a Fibre Channel uplink port-channel across the fixed and expansion modules. |
Impact of Port Mode on an Expansion Module
After you make port mode changes on an expansion module, the module reboots. All traffic through port on the expansion module is interrupted for approximately 1 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.
When 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 Standalone Configuration
A standalone 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.
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 6200 series fabric interconnect with Cisco UCS Manager, version 2.0.
Unified ports are not supported on 6100 series fabric interconnects, even if they are running Cisco UCS Manager, version 2.0.
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.
-
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.
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.
Special Considerations for UCS Manager CLI Users
Because the Cisco UCS Manager CLI does not validate port mode changes until you commit the buffer to the system configuration, it is easy to violate the grouping restrictions if you attempt to commit the buffer before creating at least two new interfaces. To prevent errors, we recommend that you wait to commit your changes to the system configuration until you have created new interfaces for all of the unified ports changing from one port mode to another.
Commiting the buffer before configuring multiple interfaces will result in an error, but you do not need to start over. You can continue to configure unified ports until the configuration satisfies the aforementioned requirements.
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 a member port for an Ethernet or FCoE port channel, Cisco UCS Manager automatically makes this port 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.
-
Cisco UCS 6100 series fabric interconnect switch can only support 1VF or 1VF-PO facing same downstream NPV switch.
Configuring the Port Mode
Caution |
Changing the port mode on either module can cause an interruption in data traffic because changes to the fixed module require a reboot of the fabric interconnect and changes on an expansion module require a reboot of that module . 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 Cisco UCS Manager CLI, there are no new commands to support Unified Ports. Instead, you change the port mode by scoping to the mode for the desired port type and then creating a new interface. When you create a new interface for an already configured slot ID and port ID, UCS Manager deletes the previously configured interface and creates a new one. If a port mode change is required because you configure a port that previously operated in Ethernet port mode to a port type in Fibre Channel port mode, UCS Manager notes the change.
Expansions modules are not supported with Cisco UCS Mini.
Procedure
Command or Action | Purpose | |
---|---|---|
Step 1 |
UCS-A# scope port-type-mode |
Enters the specified port type mode for one of the following port types:
|
Step 2 |
UCS-A /port-type-mode # scope fabric {a | b } |
Enters the specified port type mode for the specified fabric. |
Step 3 |
UCS-A /port-type-mode/fabric # create interface slot-id port-id |
Creates an interface for the specified port type. If you are changing the port type from Ethernet port mode to Fibre Channel port mode, or vice-versa, the following warning appears:
|
Step 4 |
Create new interfaces for other ports belonging to the Ethernet or Fibre Channel port block. |
There are several restrictions that govern how Ethernet and Fibre Channel ports can be arranged on a fixed or expansion module. Among other restrictions, it is required that you change ports in groups of two. Violating any of the restrictions outlined in the Guidelines and Recommendations for Configuring Unified Ports section will result in an error. |
Step 5 |
UCS-A /port-type-mode/fabric/interface # commit-buffer |
Commits the transaction to the system configuration. |
Based on the module for which you configured the port modes, data traffic for the Cisco UCS domain is interrupted as follows:
-
Fixed module—The fabric interconnect reboots. All data traffic through that fabric interconnect is interrupted. 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. Changing the port mode for both sides at once results in both fabric interconnects rebooting simultaneously and a complete loss of traffic until both fabric interconnects are brought back up.
It takes about 8 minutes for the fixed module to reboot.
-
Expansion module—The module reboots. All data traffic through ports in that module is interrupted.
It takes about 1 minute for the expansion module to reboot.
Example
The following example changes ports 3 and 4 on slot 1 from Ethernet uplink ports in Ethernet port mode to uplink Fibre Channel ports in Fibre Channel port mode:
UCS-A# scope fc-uplink
UCS-A /fc-uplink # scope fabric a
UCS-A /fc-uplink/fabric # create interface 1 3
Warning: This operation will change the port mode (from Ethernet to FC or vice-versa).
When committed, this change will require the fixed module to restart.
UCS-A /fc-uplink/fabric/interface* # up
UCS-A /fc-uplink/fabric* #create interface 1 4
Warning: This operation will change the port mode (from Ethernet to FC or vice-versa).
When committed, this change will require the fixed module to restart.
UCS-A /fc-uplink/fabric/interface* #commit-buffer
Configuring Breakout Ports
Cisco UCS 6300 Fabric Interconnect Ethernet Breakout Ports
You can configure Cisco UCS 6300 Fabric Interconnects with 40 GB Ethernet ports as four breakout 10 GB ports using a supported breakout cable. The configuration requires a Small Form-Factor Pluggable adapter (SPF) that has one 40GB QSFP+ on one end to connect to the Fabric Interconnect and four 10 GB ports to connect to different end points supporting 10 GB connectivity. For more detailed information about the Cisco UCS 6300 Fabric Interconnects, see the UCS Manager Getting Started Guide.
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. |
Once you configure a breakout port, you can configure each 10 GB sub-port as server, uplink, FCoE uplink, FCoE storage or appliance as required.
The following table summarizes the constraints for breakout functionality for Cisco UCS 6300 series fabric interconnects:
Fabric Interconnect |
Breakout Configurable Ports |

---|---|---|---|---|
UCS-FI-6332 |

13-14,27-32
|

17-34 |
1-16,35-40
|
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. |
Configuring a 10G port with QSA Adapter on Cisco UCS FI 6332
Note |
When you try to change port speeds to 1GB or 10GB, 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. 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 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. |
Configuring Multiple Breakout Ports
On a UCS 6300 Fabric Interconnect, you can specify a 40 Gigabit Ethernet port and create four 10 Gigabit Ethernet unconfigured breakout ports. Because configuring breakout on a port causes the reboot of the Fabric Interconnect, we recommend that you breakout all required ports in a single transaction.
Before you begin
Before configuring a breakout port, view the port status using the show port command.

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. The scalability ports can be used as a licensed server port for supported Cisco UCS rack servers, an appliance port, or a FCoE port.
In the Cisco UCS Manager GUI, the scalability port is displayed as Scalability Port 5 below the Ethernet Ports node. The individual breakout ports are displayed as Port 1 through Port 4.
In the Cisco UCS Manager CLI, the scalability port is not displayed, but the individual breakout ports are displayed as Br-Eth1/5/1 through Br-Eth1/5/4 .
Configuring Scalability Ports
To configure ports, port channel members or SPAN members on the scalability port, scope into the scalability port first, then follow the steps for a standard unified port.
Procedure
Command or Action | Purpose | |
---|---|---|
Step 1 |
UCS-A# scope eth-server |

Step 2 |
UCS-A /eth-server # scope fabric {a | b } |
Enters Ethernet server fabric mode for the specified fabric. |
Step 3 |
UCS-A /eth-server/fabric # scope aggr-interface slot-num port-num |
Enters ethernet server fabric aggregate interface mode for the scalability port. |
Step 4 |
UCS-A /eth-server/fabric/aggr-interface # show interface |
Displays the interfaces on the scalability port. |
Step 5 |
UCS-A /eth-server/fabric/aggr-interface # create interface slot-num port-num |
Creates an interface for the specified Ethernet server port. |
Step 6 |

Beacon LEDs for Unified Ports
Each port on the 6200 series 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. |
Configuring the Beacon LEDs for Unified Ports
Complete the following task for each module for which you want to configure beacon LEDs.
Procedure
Command or Action | Purpose | |
