Telnet Commands 95
interfaceShow
Display FSPF interface information.
Synopsis
interfaceShow [portnumber]
Availability All users
Description Use this command to display data structures associated with FSPF
interfaces (E_Ports) on the switch.
There are two data structures – the permanently allocated Interface
Descriptor Block (IDB) and the neighbor data structure that 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 a
local interface, also known as the adjacent switch. This command displays
the content of both data structures, if they have been allocated.
Used without specifying the port number, this command displays 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. The value 1000 indicates a 1 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.
