Chapter 11 Troubleshooting VSANs, Domains, and FSPF
FSPF Issues
Step 3 Use the show fspf vsan vsan-id interface command to show FSPF information.
Note To issue commands with the internal keyword, you must have an account that is a member of
the network-admin group.
switch1# show fspf vsan 1 interface fc1/16
FSPF interface fc1/16 in VSAN 1
FSPF routing administrative state is active
Interface cost is 500
Timer intervals configured, Hello 20 s, Dead 95 s, Retransmit 5 s <-----1
FSPF State is INIT <-----2
xStatistics counters :
Number of packets received : LSU 0 LSA 0 Hello 2 Error packets 1
Number of packets transmitted : LSU 0 LSA 0 Hello 4 Retransmitted LSU 0
Number of times inactivity timer expired for the interface = 0
1. The dead timer is not set to the default, so you should check the neighbor configuration.
2. FSPF is not in full state, which indicates a problem.
Step 4 Use the interface comma nd and then the fspf dead-interval command in interface mode to change the
dead interval.
Resolving a Region Mismatch Using Fabric Manager
To identify a region mismatch problem on a switch using Fabric Manager, follow these steps:
Step 1 Choose FC > Advanced > FSPF and select the General tab to verify the RegionId.
Step 2 Repeat Step 1 to determine the value of the region on the adjacent switch.
Step 3 Fill in the RegionId field to change the region and click Apply.
Resolving a Region Mismatch Using the CLI
To identify a region mismatch problem on a switch using the CLI, follow these steps:
Step 1 Use the show fspf vsan command to display the currently configured region in a VSAN.
switch# show fspf vsan 99
FSPF routing for VSAN 99
FSPF routing administration status is enabled
FSPF routing operational status is UP
It is an intra-domain router
Autonomous region is 0 /* This is the region */
SPF hold time is 0 msec
MinLsArrival = 1000 msec , MinLsInterval = 5000 msec
Local Domain is 0x78(120)
Number of LSRs = 2, Total Checksum = 0x000133de
