Viewing STP statistics
You can view a summary of STP statistics for the device. STP statistics are by default polled every
10 seconds.
To view spanning tree statistics, enter the show span command. To view STP statistics for a VLAN,
enter the span vlan command.
Clearing statistics
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.
NOTE
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.

state change last time.

stamps:
