Display FSPF interface information.
Synopsis

Description
Use this command to display data structures associated with FSPF interfaces (E_Ports) on the
switch.
There are two data structures that save data associated with FSPF interfaces:
•
the permanently allocated Interface Descriptor Block (IDB)
•
the neighbor data structure. This data structure is allocated when a switch port becomes an
E_Port
. The neighbor data structure contains all the information relating to the switch that is
connected to an adjacent switch.
This command displays the content of both data structures, if they have been allocated.
Use this command without specifying a port number to display the interface information for all
ports on the switch (including non E_Ports).
The following fields are displayed:
idbP
Pointer to IDB.
nghbP
Pointer to neighbor data structure.
ifNo
Interface number.
cost
Cost of sending a frame over the ISL connected to this interface. A value of 1000
indicates a 1 Gb/s link. A value of 500 indicates a 2 Gb/s link.
delay
Conventional delay incurred by a frame transmitted on this ISL. A fixed value
required by the FSPF protocol.
lastScn
Type of the last State Change Notification received on this interface.
lastScnTime
Time the last State Change Notification was received on this interface.
upCount
Number of times this interface came up, with respect to FSPF.
lastUpTime
Last time this interface came up.
downCount
Number of times this interface went down.
lastDownTime
Last time this interface went down.
downReason
Type of last State Change Notification that caused this interface to go down.
iState
Current state of this interface. The state can be UP or DOWN. An interface in
DOWN state does not have an allocated neighbor data structure and cannot be
used to route traffic to other switches.
state
Current state of this interface. This
E_Port
is used to route traffic to other
switches only if the state is '
NB_ST_FULL
'.
nghbCap
Neighbor capabilities. Should be 0.
nghbId
Domain ID of the neighbor (adjacent) switch.
