NO.

ype 1 and Type 2 Consistency Check Parameters

Before a Cisco Nexus 5000 Series switch brings up a vPC, the two Cisco Nexus 5000 Series switches in the same vPC domain exchange configuration information to verify if both switches have compatible configurations for a vPC topology. Depending on the severity of the impact of possible mismatched configurations, some configuration parameters are considered as Type 1 consistency check parameters while others are considered as Type 2.

When a mismatch in Type 1 parameters occur, the following applies:

•If a graceful consistency check is enabled (default), the primary switch keeps the vPC up while the secondary switch brings it down

•If a graceful consistency check is disabled, both peer switches suspend VLANs on the vPC ports.

Note The graceful consistency check is a new feature introduced in Cisco NX-OS Release 5.0(2)N2(1) and is enabled by default. For more details, see the "Graceful Consistency Check" section.

Hello Inayath

but yesterday we did same activity in our data center.

on n5k1 side we add aditional port as a member port with same parameters in running portchannel In vpc with down host.

nEw port eth 1/24

channel group 55 mode active with rest conf under port as same running on port channel.

after that we did same thing on n5k2 side. Now we have total two ports on one side in portchannel and other side also two.

Means we have four ports in vpc which is running towards downhost server.

correct me if i am wrong
