Maximum number of entries allowed in the RMON control table
You can specify the maximum number of entries allowed in the RMON control table, including alarms,
history, and events. The default number of RMON entries allowed in the RMON control table is 2048 on
the FSX 800 and FSX 1600. The maximum number of RMON entries supported is 32768.
To set the maximum number of allowable entries to 3000 in the RMON history table, enter commands
such as the following.
device(config)#system-max rmon-entries 3000
device(config)#write mem
device(config)#exit
device#reload
NOTE
You must save the change to the startup-config file and reload or reboot. The change does not take
effect until you reload or reboot.

Statistics (RMON group 1)
Count information on multicast and broadcast packets, total packets sent, undersized and oversized
packets, CRC alignment errors, jabbers, collision, fragments and dropped events is collected for each
port on a Brocade Layer 2 Switch or Layer 3 Switch.
The statistics group collects statistics on promiscuous traffic across an interface. The interface group
collects statistics on total traffic into and out of the agent interface.
No configuration is required to activate collection of statistics for the Layer 2 Switch or Layer 3 Switch.
This activity is by default automatically activated at system start-up.
You can view a textual summary of the statistics for all ports by entering the following CLI command.
device#show rmon statistics

NOTE
Though 48GC modules receive oversized packets and jabbers, they do not support count information
for oversized packets and jabbers and the output of the
show rmon statistics
command reports 0 for
both of these counters.
The
port
parameter specifies the port number. You can use the physical port number or the SNMP port
number. The physical port number is based on the product.
