Usage Guidelines If you receive bad packets on an interface, use the debug fc pkt command.
If you receive an error in processing a packet on an interface in VSAN, enter debug fspf error to get
more information. Make sure there is no misconfiguration of FSPF parameters on the two ends of the
interface. Also issue the debug fspf fc pkt command for the specific interface.
If you receive an error in flooding the local LSR in a VSAN issue the debug fspf flood and debug fspf
error commands. If error is reported in transmitting packet check if interface is up and turn on debug
fc2 error.
If you receive an error in processing a timer event for the interface in a VSAN, issue the debug fspf error
command.
If you receive an error in processing due to a wrong MTS message, use the debug fspf mts pkt and
debug fspf error commands.
If you receive an error when interacting with RIB, use the debug fspf route command along with the
RIB debug traces.
If you receive an error in computing routes for VSANs, issue the debug fspf error and the debug fspf
route commands.
If you receive an error due to the interface being stuck in a state other than FULL, use the debug fspf
event and debug fspf fc pkt commands on the interfaces involved.
