The minimum interval of one second is not fast enough to recover and
display the complete sequence of

PCM

states during the path

re-establishment phase.

A

Ring_OP

signal is received when the path is re-established indicating that

the ring is operational.

The link status indicator mounted on the SunFDDI/P card displays the
following sequence of events:

Displaying Statistics from Neighboring Stations

When you use the

pf_stat

command with the

—m

option, it displays

information about the neighboring stations attached to the local interface

pf

and the frames received from the network.

For example, to display information about the neighboring stations attached to
the interface

pf0

, type:

You can also monitor the neighboring stations dynamically (active monitor), by
specifying the interval (the elapsed time in seconds between interrogations) and
count (the total number of interrogations). The minimum interval is one second
and the accumulated statistics are displayed after every tenth interrogation.

For example, to monitor the stations attached to

pf0

once every 10 seconds for

1 minute (a total of 6 interrogations), type:
