Displays FSPF interface information.
SYNOPSIS interfaceshow [slot/][port]
DESCRIPTION Use this command to display the two data structures associated with FSPF interfaces (E_Ports) on the
switch:
•
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.
The following fields are displayed:
idbP
Pointer to IDB.
nghbP
Pointer to neighbor data structure.
ifNo
Interface number.
masterPort
Port number of the trunk master port, if present, of the trunk group of which this
port is a part.
defaultCost
Default cost of sending a frame over the interswitch link (ISL) connection to this
interface.
cost
Cost of sending a frame over the ISL connected to this interface. A value of 1000
indicates a 1-Gbps link. A value of 500 indicates a 2-Gbps link. For links with a
bandwidth greater than 2 Gbps, the cost is 500. For links with less than 1 Gbps,
the cost is 2000. Refer to linkCost for more information.
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.
