N7010 SUP1 to SUP2E Upgrade Process - VPC Concerns

[Brent Leekley]

***Apologies for asking for advice on such old hardware.

I have a customer who  has stalled on SUP2E upgrade because they have a hard requirement for zero downtime.

They have 2x7010 dual Sup1.  They've had the replacement SUP2E's on the shelf for a year.  HA works well enough that one 7K can be taken offline to perform the SUP2E upgrade.  The concern is what happens to the vPC domain once they upgraded chassis 1 to the SUP2E and attempt to move traffic over to take down the second chassis?

Anyone have experience here? 

Thank you

Hi mate

This should help.....  there are other things to consider outside of VPC

In theory, VPC should be supervisor neutral. If your consistency checks (see below) are good then you should be ok. I would go through the bug list for both the hardware and nx-os with a fine tooth-comb though - it would be more likely this and not VPC itself you'd have issue with.

Types of consistency checks:
