interfaceShow
The
interfaceShow
command displays FSPF interface information. This includes
static information about the port (for example, variables allocated even when a port is
down), and “neighbor” information which includes variables associated with the
remote switch connected to the port. A FSPF interface corresponds to an E_Port. The
static information fields are described in Table 4-20. Neighbor information fields are
described in Table 4-21.
With no parameters, it shows the information for all switch interfaces. The command
syntax is
interfaceShow
<port#>
.

Descriptions
Field Description
idbP The current neighbor state. Its value must be NB_ST_FULL
for the ISL to forward frames to the adjacent switch. Other
values may be transitory, however if a value is retained for
more than ten seconds, contact Dell for technical assistance.
nghbP Neighbor capabilities has a value of 0.
ifNo The port number. It should be identical to the value specified
in the command line.
cost The cost of sending a frame over the ISL connected to this
port. The value 1000 indicates a 1-gigabits per second (Gbps)
link.
delay The conventional delay incurred by a frame transmitted on
this ISL. It is required by the FSPF protocol, and is a fixed
value.
lastScn Last State Change Notification (SCN) received on this
interface.
lastScnTime Time the last SCN was received.
upCount The number of times this interface initialized (the transition
number from an offline to E_Port state).
