Modifications

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

Use this command to enable a port profile to apply the port profile configurations to the interfaces. You can configure and inherit a port profile onto a range of interfaces before you enable that port profile. You must then enable that port profile for the configurations to take effect on the specified interfaces.

Examples

This example shows how to enable a port profile named ppEth that is configured for Ethernet interfaces:

switch# configure terminal
switch(config)# port-profile ppEth
switch(config-port-prof)# state enabled
switch(config-port-prof)#
 

This example shows how to disable a port profile named ppEth that is configured for Ethernet interfaces:

switch# configure terminal
switch(config)# port-profile ppEth
switch(config-port-prof)# no state enabled
switch(config-port-prof)#

Command Default

None

 
Command Modes

Configuration synchronization mode

 
Command History

Release
Modifications

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

Use this command to create a switch profile on each of the peer switches. You must use the same profile name on both the switches in the Cisco Fabric Services (CFS) peer configuration.

Note In this release of Cisco NX-OS, only a pair of switches can be configured as a peer.

You can configure only one active switch profile on each peer switch. If you create or configure a second switch profile, you see the following error message:

Error: Another switch profile already exists. Cannot configure more than one switch-profile.
 

The configuration that is made locally on the switch is synchronized and made available on the peer switch only after the connectivity is established between the peer switches and the configuration is verified and committed on the local switch.

You can configure a switch profile to include the interface configuration, quality of service (QoS), and virtual port channel (vPC) commands. FCoE commands are not supported on a switch profile.

When you delete a switch profile, you can choose to delete the local switch profile with the local configurations on the switch, or delete the switch profile with the local configurations and configuration information in the peer. The peer becomes unreachable.

Examples

This example shows how to create a switch profile named s5600 on switch 1 of the peer:

Peer A

switch# configure terminal
switch(config)# cfs ipv4 distribute
switch(config)# exit
switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# switch-profile s5600
Switch-Profile started, Profile ID is 1
switch(config-sync-sp)#
 

This example shows how to create a switch profile named s5600 on switch 2 of the peer:

Peer B

switch# configure terminal
switch(config)# cfs ipv4 distribute
switch(config)# exit
switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# switch-profile s5600
Switch-Profile started, Profile ID is 1
switch(config-sync-sp)#
 

This example shows how to delete a switch profile named s5600 and its local configuration on switch 1 of the peer:

Peer A

switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# no switch-profile s5600 local-config
switch(config-sync)#

This command was introduced.

 
Usage Guidelines

Before you use this command, make sure that you enable Adapter Fabric Extender (Adapter-FEX) on the switch by using the feature adapter-fex command.

A virtual network tag (VNTag) port helps to identify the virtual interfaces on that physical port.

Examples

This example shows how to set an interface as a VNTag port:

switch(config)# interface ethernet 1/5
switch(config-if)# switchport mode vntag
switch(config-if)#
 

This example shows how to remove a VNTag port from an Ethernet interface:

switch(config)# interface ethernet 1/5
switch(config-if)# no switchport mode
switch(config-if)#

Command History

Release
Modifications

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

Use this command to add the peer switch that will be included in the synchronization. You must have the IPv4 address of the peer switch. You can ensure that configuration synchronization is enabled on the peer switch by using the config sync command.

After you add a peer to a switch profile, you can add commands to the switch profile.

Peers maintain a configuration revision of their local configuration as well as the revision. After a network outage, when connectivity is established between the peer switches and the peers are reachable, each peer determines if any configuration in the switch needs to be synchronized with the other peer. Changed configurations will then be synchronized between the peers.

When you remove a peer from the switch profile, all configuration information about the peer is deleted from the local switch.

Examples

This example shows how to add a peer switch with IPv4 address 192.0.2.37 to a switch profile named s5600 on switch 1 of the peer:

Peer A

switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# switch-profile s5600
Switch-Profile started, Profile ID is 1
switch(config-sync-sp)# sync-peers destination 192.0.2.37
switch(config-sync-sp)#
 

This example shows how to add a peer switch with IPv4 address 192.0.2.3 to a switch profile named s5600 on switch 2 of the peer:

Peer B

switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# switch-profile s5600
Switch-Profile started, Profile ID is 1
switch(config-sync-sp)# sync-peers destination 192.0.2.3
switch(config-sync-sp)#
 

This example shows how to delete a peer with IPv4 address 192.0.2.37 from a switch profile named s5600 on switch 1 of the peer:

Peer A

switch# config sync
Enter configuration commands, one per line. End with CNTL/Z.
switch(config-sync)# switch-profile s5600
switch(config-sync-sp)# no sync-peers destination 192.0.2.37
switch(config-sync-sp)#

Modifications

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

When you create a vPC domain, the Cisco NX-OS software automatically creates a vPC system MAC address, which is used for operations that are confined to the link-scope, such as the Link Aggregation Control Protocol (LACP). However, you may choose to configure the vPC domain MAC address manually.

Examples

This example shows how to configure the MAC address for the vPC domain:

switch(config-vpc-domain)# system-mac 23fb.4ab5.4c4e
switch(config-vpc-domain)#

Command History

Release
Modifications

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

We recommend that you manually configure the vPC system priority when you are running Link Aggregation Control Protocol (LACP) to ensure that the vPC peer devices are the primary devices on LACP. When you manually configure the system priority, ensure that you configure the same priority value on both vPC peer devices. If these values do not match, vPC will not come up.

Examples

This example shows how to configure the system priority for the vPC domain:

switch(config-vpc-domain)# system-priority 3000
switch(config-vpc-domain)#
