N5k, vPC consistency check

minghui.qi
Level 1
Level 1

hi all,

I got a pair of 5548, vPC works great. However the vPC consistency check show the two switch configs are different! I don't know why vPC still works fine. See the below output of the show vpc consistency-parameters global command. it's weird that from output of each switch, the local value is different from peer value, but if you just see the local value from both switch, they are the same. what's going on here?

thanks

ming

This is related to the following bug

CSCtl06882 - 'show vpc consistency-parameters global' showing incorrect value for QoS

This defect is currently Assigned State but is Cosmetic in Nature, not service impacting. Hence you will have no problem with vpc.

Thanks, Vinayak

I thought it must be a cosmetic bug, great to get confirmation. Thanks a lot.
