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.
Syntax: system-max rmon-entries value
where value can be:
• 1536 - 32768 for FSX 800 and FSX 1600 devices
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

Syntax: show rmon statistics [ethernet port]
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.
The SNMP numbers of the ports start at 1 and increase sequentially. For example, if you are using a
Chassis device and slot 1 contains an 8-port module, the SNMP number of the first port in slot 2 is 9.
The physical port number of the same port is 2/1.
This command shows the following information.
