RMON support
RMON support
The RMON agent supports the following groups. The group numbers come from the RMON
specification (RFC 1757):
• Statistics (RMON Group 1)
• History (RMON Group 2)
• Alarms (RMON Group 3)
• Events (RMON Group 9)
The CLI allows you to make configuration changes to the control data for these groups, but you
need a separate RMON application to view and display the data graphically.
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 devices. 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.
TurboIron(config)#system-max rmon-entries 3000
TurboIron(config)#write mem
TurboIron(config)#exit
TurboIron#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.
Syntax: system-max rmon-entries <value>
where <value> can be:
• 1536 – 32768 for TurboIron X Series 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 Layer 2 Switch or Layer 3 Switch.
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.
