Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Ensure that the connected Fabric Extender is online.
You must configure both switches on either side of the vPC peer link with the following procedure.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies an interface to configure, and enters
interface configuration mode.
switch(config)# interface ethernet
chassis/slot/port
Step 2
Creates an EtherChannel host interface on the
selected host interface.
switch(config-if)# channel-group
channel-number mode {active | passive |
on}
Step 3
(Optional)
Displays information about each EtherChannel
host interface.
switch# show port-channel summary
Step 4
(Optional)
Copies the running configuration to the startup
configuration.
switch# copy running-config
startup-config
Step 5
This example shows how to configure an EtherChannel host interface:
switch# configure terminal
switch(config)# interface ethernet 101/1/20
switch(config-if)# channel-group 7 mode active
Moving Other EtherChannels into a vPC
To connect to the downstream switch, you create a EtherChannel from the downstream switch to the primary
vPC peer switch and you create another EtherChannel from the downstream switch to the secondary peer
switch. Finally, working on each vPC peer switch, you assign a vPC number to the EtherChannel that connects
to the downstream switch. You will experience minimal traffic disruption when you are creating vPCs.
Before You Begin
Ensure that you have enabled the vPC feature.
You must configure both switches on either side of the vPC peer link with the following procedure.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Selects the EtherChannel that you want to put into the vPC to
connect to the downstream switch, and enters the interface
configuration mode.
switch(config)# interface
port-channel channel-number
