Viewing Port Monitoring Statistics (pmstat)
The pmstat command displays the statistics gathered for the current or most recent port moni-
toring session. If a port monitoring session is currently in progress, then it displays the results
of the in-progress session. If a port monitoring session is not in progress, then it displays
results of the most recently completed session. To view session statistics, enter
pmstat
A screen similar to the following displays:
Viewing capture statistics:
Percent RAM available: 96%
Frame type #Frames
------------------ --------------
Broadcast 108
Multicast 253
Unicast 301
The Percent RAM available indicates how much of the configured RAM disk has been used by
this port monitoring session. You can configure the size of the RAM disk through the pmcfg
command; the default size is 1 MB. The remaining items in the display show the number of
packets passed on the port broken down into broadcast, multicast, and unicast frames.
