RMON support
where <value> can be:
• 1536 – 32768 for FSX 800 and FSX 1600 devices
• 128 – 32768 for FESX 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.
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 statisitics 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. If you specify a physical
port, specify the <port> variable in one of the following formats:
• FCX stackable switches – <stack-unit/slotnum/portnum>
• FSX 800 and FSX 1600 chassis devices – <slotnum/portnum>
• FESX compact switches – <portnum>
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.
