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
nghbP
ifNo
cost
delay
lastScn
lastScnTime Time the last State Change Notification was received on this interface.
upCount
lastUpTime
downCount
lastDownTime

1-100
Pointer to IDB.
Pointer to neighbor data structure.
Interface number.
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.
Conventional delay incurred by a frame transmitted on this ISL. A fixed value
required by the FSPF protocol.
Type of the last State Change Notification received on this interface.
Number of times this interface came up, with respect to FSPF.
Last time this interface came up.
Number of times this interface went down.
Last time this interface went down.
Type of last State Change Notification that caused this interface to go down.
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.
Current state of this interface. This E_Port is used to route traffic to other
switches only if the state is 'NB_ST_FULL'.
Neighbor capabilities. Should be 0.
Domain ID of the neighbor (adjacent) switch.
