You can clear statistics for many parameters with the clear option.
To determine the available clear commands for the system, enter the following command.
BigIron RX# clear ?
Syntax: clear <option>
You also can enter “clear” at the command prompt, then press the TAB key.
Clear commands are found at the Privileged EXEC level.
RMON support
The Brocade 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.
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 device.
No configuration is required to activate collection of statistics for the device. 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.
BigIron RX(config)# show rmon statistics
