Cisco Nexus 1000V Port Profile Configuration Guide, Release 4.2(1) SV1(4)

Creating Port Profiles

This chapter describes how to create, enable, or remove a port profile or add VMware attributes, access or trunk ports, ACLs, and NetFlow.

This chapter includes the following sections:

•Information About Port Profiles

•Guidelines and Limitations

•Default Settings

•Configuring Port Profiles

•Additional References

•Feature History for Port Profiles

Information About Port Profiles

Port profiles simplify interface configuration by defining policies that can be reused for multiple interfaces. For more information about port profiles, see Chapter 1 "Overview."

Port Profile States

A port profile can be in one of two states: enabled or disabled. Port profiles are disabled by default. Table 2-1 describes port profile behavior in these two states.

To enable a port profile, see the "Enabling a Port Profile" procedure.

Table 2-1 Port Profile States
State	Behavior
Disabled (the default)	When disabled, a port profile behaves as follows: •Its configuration is not applied to assigned ports. •If exporting policies to a VMware port group, the port group is not created on the vCenter Server.
Enabled	When enabled, a port profile behaves as follows: •Its configuration is applied to assigned ports. •If configured with the VMware port-group attribute, the port group is created on the vCenter Server.

vEthernet Port Binding

You can configure either static or ephemeral port binding for vEthernet port profiles. Table 2-2 shows how this setting controls how ports are assigned in the VMware port group.

Table 2-2 vEthernet Port Binding
Type	Behavior
Static (the default)	A DVPortID is assigned from the port group pool when you first assign the port group to the port. The DVPortID persists for the life of the network adapter. The port group has a fixed number of ports.
Ephemeral	A new DVPortID is assigned to the port every time the VM is powered on. The port keeps this same DVPortID while the VM is up. All available DVS ports are shared. Ports are not allocated from the port group pool. Note If a system administrator changes the port profile assignment for an interface, any manual configuration on the interface is purged if either port profile is configured with ephemeral port binding. This purging of manual configurations occurs regardless of your auto purge setting. For more information about configuring svs veth auto-config-purge, see the Cisco Nexus 1000V Interface Configuration Guide, Release 4.2(1)SV1(4).

Guidelines and Limitations

Use the following guidelines and limitations when configuring port profiles:

•Once a port profile is created as either an Ethernet or vEthernet type, you cannot change the type.

•In an installation where multiple Ethernet port profiles are active on the same VEM, it is recommended that they do not carry the same VLAN(s). The allowed VLAN list should be mutually exclusive. Overlapping VLANs can be configured but may cause duplicate packets to be received by virtual machines in the network.

•To maintain consistency between the port profile definition and what is applied to an interface, if a port profile modification is rejected by any port, the modification is rejected by the port profile too.

•If you create a port profile with a command error, for example a private VLAN mapping error or service policy map error, then an attempt to apply this port profile to an interface shuts down the interface. The error is not copied to the interface and a system message is generated with details of the error. In this case, you must correct the error in the port profile. Then return the interface to service and apply the corrected port profile using the following command sequence:

1. no shutdown

2. default shutdown

For more information, see the Cisco Nexus 1000V Troubleshooting Guide, Release 4.2(1)SV1(4).

•MTU can only be configured for uplink, Ethernet type port profiles.

•If you configure MTU for any Ethernet port profile, your ESX host may generate the following error:

2010 Nov 15 04:35:27 my-n1k %VEM_MGR-SLOT3-1-VEM_SYSLOG_ALERT: vssnet : 
sf_platform_set_mtu: Failed setting MTU for VMW port with portID 33554475.

In this case, the MTU value you have set is not supported by the VEM physical NIC. See your VMware documentation for more information about supported MTU for PNIC.

•Before configuring a port profile, the Cisco Nexus 1000V software must be initially configured. For information, see the Cisco Nexus 1000V Getting Started Guide, Release 4.2(1)SV1(4).

•The Cisco Nexus 1000V must be connected to the vCenter Server.

2. port-profile [type {ethernet | vethernet}] name

3. (Optional) description profiledescription

4. show port-profile [brief | expand-interface | usage] [name profile-name]

5. copy running-config startup-config

DETAILED STEPS


	Command	Description
Step 1	config t Example: n1000v# config t n1000v(config)#	Enters global configuration mode.
Step 2	port-profile [type {ethernet \| vethernet}] name Example: n1000v(config)# port-profile type ethernet AllAccess1 n1000v(config-port-prof)#	Enters port profile configuration mode for the named port profile. If the port profile does not already exist, it is created using the following characteristics: •name—The port profile name can be up to 80 characters and must be unique for each port profile on the Cisco Nexus 1000V. •type—(Optional) The port profile type can be Ethernet or vEthernet.

Configuring Port Mode

You can use the following procedures to designate trunking or access ports and configure VLANs for an existing port profile.

•Configuring a Trunking Profile

•Configuring an Access Profile

•Clearing a Port Management Policy

BEFORE YOU BEGIN

Before beginning the procedures in this section, you must know or do the following:

•You are logged in to the CLI in EXEC mode.

•You know whether you are configuring the port profile as an access port or trunk port.

–An access port transmits packets on only one untagged VLAN. You can specify the VLAN, and it becomes the access VLAN. If you do not specify a VLAN for an access port, that interface carries traffic only on the default VLAN 1.

–A trunk port transmits untagged packets for the native VLAN and transmits encapsulated, tagged packets for all other VLANs.

•You know the needed VLAN configuration for this port profile.

•A VLAN must already be created on the switch before you can assign it to a port profile.

•You know the VLAN ID for the VLAN that you are assigning.

•VLAN 1 is the default VLAN. You cannot create, modify, or delete this VLAN.

•In accordance with the IEEE 802.1Q standard, up to 4094 VLANs are supported. Table 2-4 describes the available VLAN ranges and their use.

Table 2-4 VLAN Ranges
VLANs Numbers	Range	Usage
1	Normal	Cisco default. You can use this VLAN, but you cannot modify or delete it.
2-1005	Normal	You can create, use, modify, and delete these VLANs.
1006-4094	Extended	You can create, name, and use these VLANs. You cannot change the following parameters: •State is always active. •VLAN is always enabled. You cannot shut down these VLANs.
3968-4047 and 4094	Internally allocated	These 80 VLANs, plus VLAN 4094, are allocated for internal device use. You cannot create, delete, or modify any VLANs within the block reserved for internal use.

Configuring a Trunking Profile

You can use this procedure to define a trunking port profile including the VLANs that are allowed on the interfaces.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

•You are logged in to the CLI in EXEC mode.

•You have already created the port profile using the "Creating a Port Profile" procedure.

•You know the needed VLAN configuration for this port profile and that it is to be used in trunk mode.

•A VLAN must already be created on the switch before you can assign it to a port profile.

•You know the supported VLAN ranges described in Table 2-4.

•If you do not configure allowed VLANs in this procedure, then the default VLAN 1 is used.

•If you do not configure a native VLAN in this procedure, then the default VLAN 1 is used.

•You are logged in to the CLI in EXEC mode.

•You have already created the port profile using the "Creating a Port Profile" procedure.

SUMMARY STEPS

1. config t

2. port-profile [type {ethernet | vethernet}] name

3. state enabled

4. show port-profile [brief | expand-interface | usage] [name profile-name]

5. copy running-config startup-config

DETAILED STEPS


	Command	Description
Step 1	config t Example: n1000v# config t n1000v(config)#	Enters global configuration mode.
Step 2	port-profile [type {ethernet \| vethernet}] name Example: n1000v(config)# port-profile AccessProf n1000v(config-port-prof)#	Enters port profile configuration mode for the named port profile.
Step 3	state enabled Example: n1000v(config-port-prof)# state enabled n1000v(config-port-prof)#	Enables the port profile and applies its configuration to the assigned ports. If the port profile is a VMware port group, the port group will be created in the vswitch on vCenter Server.
Step 4	show port-profile [brief \| expand-interface \| usage] [name profile-name] Example: n1000v(config-port-prof)# show port-profile name AccessProf	(Optional) Displays the configuration for verification.
Step 5	copy running-config startup-config Example: n1000v(config-port-prof)# copy running-config startup-config	(Optional) Saves the running configuration persistently through reboots and restarts by copying it to the startup configuration.

EXAMPLES

This example shows how to enable a port profile:

n1000v# config t

n1000v(config)# port-profile AccessProf

n1000v(config-port-prof)# state enabled

n1000v(config-port-prof)# show port-profile name AccessProf

port-profile AccessProf

Removing a Port Profile

You can use this procedure to remove a port profile.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

•You are logged in to the CLI in EXEC mode.

•If the port profile is inherited by another port profile, you need to remove the inheritance from the other port profile before removing this port profile. If you do not remove the inheritance first, the procedure fails. See Removing Inherited Policies from a Port Profile.

•When you remove a port profile that is mapped to a VMware port group, the associated port group and settings within the vCenter Server are also removed.

SUMMARY STEPS

1. config t

2. (Optional) show port-profile virtual usage name profile_name

3. no port-profile profile_name

4. show port-profile name profile_name

5. copy running-config startup-config

DETAILED STEPS


	Command	Description
Step 1	config t Example: n1000v# config t n1000v(config)#	Enters global configuration mode.
Step 2	show port-profile virtual usage name profile_name Example: n1000v(config)# show port-profile virtual usage name AccessProf	(Optional) Verifies if active interfaces use this port profile. Note You cannot remove a port profile if there are active interfaces associated with it.
Step 3	no port-profile profile_name Example: n1000v(config)# no port-profile AccessProf n1000v(config)#	Removes the port profile configuration and operational settings.
Step 4	show port-profile name profile_name Example: n1000v(config)# show port-profile name AccessProf ERROR: port-profile AccessProf does not exist n1000v(config)#	(Optional) Verifies that the port profile does not exist.
Step 5	copy running-config startup-config Example: n1000v(config-port-prof)# copy running-config startup-config	(Optional) Saves the running configuration persistently through reboots and restarts by copying it to the startup configuration.

EXAMPLES

This example shows how to remove a port profile:
