Chapter 11 Troubleshooting VSANs, Domains, and FSPF
FSPF Issues
Step 2 Use the debug fspf all command and look for nonexistent region messages.
switch1# debug fspf all
Jan 5 00:39:31 fspf: FC2 packet received for non existent region 0 in VSAN 1 <-----1
Jan 5 00:39:33 fspf: FC2 packet received for non existent region 0 in VSAN 1
Jan 5 00:39:45 fspf: Interface fc1/1 in VSAN 1 : Event INACTIVITY , State change INIT ->
INIT
Jan 5 00:39:45 fspf: Interface fc1/2 in VSAN 1 : Event INACTIVITY , State change INIT ->
INIT <-----2
1. The neighbor switch advertising region is 0.
2. FSPF is in init state for each ISL.
Tip We recommend that you open a second Telnet or SSH session before entering any debug
commands. If the debug output overwhelms the current session, you can use the second session
to enter the undebug all command to stop the debug message output.
Step 3 Use the undebug all command to turn off debugging.
Step 4 Use the show fspf command to show FSPF configuration and check the autonomous region.
Step 5 Use the fspf config vsan command to enter the FSPF configuration mode and use the region command
to change the region.
The region must match on all switches in the VSAN.
