Combine two links from different module in the N7k VPC peer link

[Muhannad Abu Shamma]

Dears,

Can i combine two links from different module in the N7k VPC peer link as follows:

N7K-1     VPC Peer link    N7K-2

M2    -----------------------  M2

M1    ----------------------   M1

Is this is supported or the VPC peer link should not be mixed and only from one type line card?

Regards,

Muhannad

Hi

does not look like its supported on 6.1 or below anyway , what version are you running

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/interfaces/configuration/guide/b-Cisco-Nexus-7000-Series-NX-OS-Interfaces-Configuration-Guide-Book/configuring-vpcs.html

vPC Peer Link and I/O Modules Support in Cisco NX-OS Release 6.1 and Earlier Releases

In Cisco NX-OS Release 6.1 and earlier releases, only identical I/O modules on either side of a vPC peer link are supported. Using different I/O modules on either side of a vPC peer link is not supported. Mixing I/O modules on the same side of a port channel is also not supported. The table above displays the I/O modules that are supported on both sides of a vPC peer link.

While using port channels, we recommended that you use identical line cards on both sides.

Hi Mark,

Thanks for your response, i am running version 6.2, does this make any difference?

Can i combine the ports from different line cards (M1 and M2)?

HI

looking at the docs no , not in 6.2 either , looks liken the 6 release is all the same

The vPC peer-link interfaces must be on the same module type on both vPC peers as described in the vPC Peer Link and I/O Modules Support In Cisco NX-OS Release 6.2 section of the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 6.x.
