VPC peer-link between Nexus 5010 and 5020

[chun.zhang]

Hi

I'm trying to create a vpc between a Nexus 5010 and Nexus 5020 switch. I recently upgraded the software so they are running the same version. However, I connect get a vpc link. Is there something wrong with my setup? Is a vpc between a 5010 and 5020 even possible? They are connected using a pair of Intel X520's in 802.3AD teaming mode. Thanks in advance.

Hi,

Can you add this command to both devices:

peer-keepalive destination 172.25.182.51 source 172.25.182.52 vrf management

peer-keepalive destination 172.25.182.52 source 172.25.182.51 vrf management

Also do you have a portchannel configured?

Have a look at this link for config example:

Thanks for the reply. I took down my existing vpc configuration (no'ed everything) and I went to the nexusfu url and followed the steps identically (except ip addresses) up until the show vpc. However, this is what I get on both switches (below). It indicates that the peer link is down, but the peer is alive?

Edit:

Nevermind! I had to do a write-erase and reload of one of the switches due to a policy map issue (probably left over from when I ugpraded the switch software. Everything works now.
