FSPF routing for VSAN 200
FSPF routing administration status is enabled
FSPF routing operational status is UP
It is an intra-domain router
Autonomous region is 2
SPF hold time is 0 msec
MinLsArrival = 1000 msec , MinLsInterval = 2000 msec
Local Domain is 0x22(34)

FSPF routing for VSAN 200
FSPF routing administration status is enabled
FSPF routing operational status is UP
It is an intra-domain router
Autonomous region is 0
SPF hold time is 0 msec
MinLsArrival = 1000 msec , MinLsInterval = 2000 msec
Local Domain is 0x18(24)
Number of LSRs = 2, Total Checksum = 0x00014f9f
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.
Example:
switch(config)# fspf config vsan 200
switch(config-(fspf-config))# region 0
Fibre channel port is suspended due to too many invalid FLOGIs
A Fibre Channel node that is connected to an NPV feature-enabled Cisco Nexus 5000 switch or a Cisco
Nexus 5000 switch that is running in fabric mode cannot log into the SAN fabric due to a FLOGI
rejection.
The following example shows possible log messages from the
show logging
command log.
Example:
%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR: %$VSAN <vsan-id>%$ [VSAN <vsan-id>, Interface
fcslot/port/: mode[F]] FLOGI rejected - FCID allocation failed.
PORT-5-IF_DOWN_TOO_MANY_INVALID_FLOGIS: %$VSAN <vsan-id>%$ Interface fc slot/port is down
(Suspended due to too many invalid flogis
The status of the interface shows invalidFlogis.

Possible Cause
The FC ID persistency table for that VSAN might be full. If the Nexus 5000 Series switch is configured
as an NPV edge switch, the FC ID persistency table of the NPV core switch might be full.
FC IDs:
When an N port logs into a Cisco Nexus 5000 Series switch, it is assigned an FC ID. By default, the
persistent FC ID feature is enabled. If this feature is disabled, the following situations can occur:
