Nexus5672UP change the vpc peer-link from 40gig to 10Gig

[dganta]

Hi,

My customer has a requirement of changing the 40Gig vPC peer-link to 10Gig vPC peer-link for Nexus5672up. The Nexus5672UP is a part of Flexpod environment at this point and is in production with the UCS and FI and Netapp. Would like to know what is the best way of changing the 40Gig vPC peer-link port channel with a minimal impact on the production network.

Hi All,

I have done this change last week. Just to help if someone is looking for the same.

Following are the steps done with Minimal impact for changing the 40Gig vPC peer-link to 10Gig vPC peer-link.

Interface port-channel 1
shut
This will shutdown the vpc peer-link and the vPC secondary peer will suspend all the vpc ports while the primary ones are active

> Change the speed of the port change to 10Gbps from 40Gbps

interface port-channel 1
speed 10000

If the speed of the port-channel is not changed port-channel cannot be created with 10Gig interface

interface eth1/37-38
switchport mode trunk
channel-group 1 mode active
!
interface eth2/1-2
no channel-group 1 mode active
!
interface eth2/1-2
shut
!
interface port-channel 1
no shut
