Enter the show interface san-port-channel <channel-id> command to view the isolation error for the
specific VSAN.
Example:
switch(config)# show interface san-port-channel 200
san-port-channel 200 is trunking (Not all VSANs UP on the trunk)
Hardware is Fibre Channel
Port WWN is 24:c8:00:0d:ec:d5:a3:80
Admin port mode is auto, trunk mode is on
snmp link state traps are enabled
Port mode is TE
Port vsan is 1
Speed is 8 Gbps
Trunk vsans (admin allowed and active) (1,200)
Trunk vsans (up)
Trunk vsans (isolated)
Trunk vsans (initializing)
Use the show fcdomain domain-list vsan <vsan-id> command to view which domains are currently in
Step 2
your fabric.
Example (switch is isolated because of a domain ID 44 overlap):
switch(config)# show fcdomain domain-list vsan 3
Number of domains: 1
Domain ID
---------
0x2c(44)
switch(config)# show fcdomain domain-list vsan 3
Number of domains: 1
Domain ID
---------
0x2c(44)
If the isolation occurred for a specific VSAN under a SAN port channel interface, you can view the error
with the show port internal info interface san-port-channel <channel-id> vsan <vsan-id> as shown
in the following example:
Example:
switch(config)# show port internal info interface san-port-channel 200 vsan 200
san-port-channel 200, Vsan 200 - state(down), state reason(Isolation due to domain other
side eport isolated), fcid(0x000000)
port init flag(0x10000),
Lock Info: resource [san-port-channel 200, vsan 200]
