Hi Team
We are migrating some of our Cross Site DWDM SAN links on our Cisco SAN
I am look for a way by which i can track the Extended ISL distance ( current as well as migraiton )
I can see that all the SAN ports are TE and each has 500 buffer credits allocated. How do i know if these buffer credits are enough ??
Is there any useful command which i can use to collect the TE port config before and after the change which will indicate if the link is healthy after the migration ??
Also the SAN port connected to the link being migrated is part of port channel . can i leave the port in port channel during the link migration ??
Appreciate your quick response in this regard
