VPC Connection

[mhebert2]

I have two Nexus 5010 connected as a pair runnint IOS n5000-uk9.4.1.3.N2.1.bin. I have two upgrade the Nexus 5010 to newer IOS. Will the VPC channel connecter to cisco 3750 switches go in error disable if one is running the current version and the other is running the newer version of IOS in a live network.

Hi Hebert,

Follow upgrade guide step-by-step and there shouldn't be any issues.

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/upgrade/513_N1_1/n5k_upgrade_downgrade_513.html

During the upgrade running different versions on vpc peers is acceptable and won't cause link errors.

HTH,

Alex
