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.
ARing_OP signal is receivedwhen the path is re-established indicating that
the ring is operational.
The link status indicator mounted on the SunFDDI/P card displays the

Displaying Statistics fromNeighboring 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<inst> and the frames received from the network.
For example, to display information about the neighboring stations attached to
the interface pf0, type:
Youcan also monitor the neighboring stations dynamically (active monitor), by
specifyingthe interval(the elapsed timein 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:
#<basedir>/pf_stat —m pf0
