VPC Compatibility issues on N7k?

Answered Question
May 21st, 2009

I'm trying to get VPC working on a NX7k that's got a few of the N7K-M148GT-1 copper modules installed.

Whenever I have these linecards installed, VPC complains that it's not available:

vPC enable status: Incompatible hardware not enabling vPC

disabling the copper linecards allows me to now enable VPC. When I re-enable the copper linecards, they show an "ok" status in the output of show module, but they're not available in the box to configure. The interfaces don't show up in any status outputs, I can't configure them, etc.

I've made sure that I've got the latest EPLD installed on every device in these 7ks.

n7000-s1-epld.4.1.4.img

What is suspicious is that I have V1.0 linecards:

2 48 10/100/1000 Mbps Ethernet Module N7K-M148GT-11 ok

2 4.1(3) 1.0

Is anybody aware of a hardware revthat'd make this an incompatible configuration? I can't find any documentaion regarding VPC requirements anywhere.

(I also have some N7Ks with v1.3 hardware- and that doesn't seem to have any issues with VPC. So I've got a sinking suspicion that I'm stuck.)

I have this problem too.

Yes, as a minimum you need 1.3 h/w rev 10/100/1000 Mbps Ethernet Module (N7K-M148GT-11).

open a TAC case, they can assist you with hardware replacements at no charge to you.
