Hi all
Can i configure a vpc between N7K-SUP1 and N7K-SUP2E?
I have two N7K with SUP1 and i have to upgrade the hardware of both to SUP2, but i can´t shutdown the two N7K, i have support all traffic in one, upgrade harware in number 2 and "synchronize" the vpc for 2 differents supervisors (SUP1 - SUP2). Also we have some N5K connected in vpc to this N7K..............Remeber buddyes, no interruption.
Thanks in advance for your help.

Hi Reza
But in a maintenance window to use this configuration for 2 days between changes its ok? did you know what i have to take care in this scenario?

Hi,
I have never done this before, but as far as I know you don't have to have the same exact sup for vPC to work. As long as the OS versions are the same and you can configure vPC between sup-1 and sup-2 than it should work for as long as needed. Can you post a diagram of your topology showing what devices (if any FEX) and how are they connected to these 7ks?

Hi ,
I have a similar scenario where I need to upgrade N7K chassis running on sup1/fab1 to sup2/fab2 running in VPC setup.
Can we upgrade single chassis at time and maintain VPC compatibility until we upgrade both chassis?
On NX-OS version, can we use ISSU compatible versions during the upgrade, as mentioned in below document?
