How to bring up FCIP connections

A fluctuation in Ethernet connection can cause the FCIP connection to go offline. If Ethernet connections comes online again, FCIP will still stay offline. It can be brought online as below:

How to switch over (failover) from active or standby supervisor and vice versa?

For high availability, ethernet port for both active and standby supervisors should be connected to the same network or virtual LAN. The active supervisor owns the one IP address used by these ethernet connections. On a switchover, the newly activated supervisor takes over this IP address.

While configuring the switch, if you get error message “Fabric is already locked” what to do?

Check current locks

switch# show cfs lock
Application: flex-attach
Scope      : Physical-fc-ip
--------------------------------------------------------------------------------
 Switch WWN              IP Address                   User Name    User Type
--------------------------------------------------------------------------------

Total number of entries = 1
switch# clear flex-attach session
switch# show cfs lock

How to find out which switches are in given VSAN?

switch# show fabric switch information vsan 123
Output should be same on all the switches in that vsan

Check VSAN membership of ports

switch# show vsan membmership
