Viewing STP Statistics
You can view a summary of STP statistics for Layer 2 Switches and Layer 3 Switches. 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:
FESX424 Router# clear ?
Syntax:
clear <option>
You also can enter “clear” at the command prompt, then press the TAB key.
For a complete summary of all available
clear
...
CLI commands and their displays, see the
Foundry Switch and
Router Command Line Interface Reference
.
NOTE:
Clear commands are found at the Privileged EXEC level.
RMON Support
The Foundry 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.
InFlowCtrlPkts
The total number of flow control packets received.
OutFlowCtrlPkts
The total number of flow control packets transmitted.
InBitsPerSec
The number of bits received per second.
OutBitsPerSec
The number of bits sent per second.
InPktsPerSec
The number of packets received per second.
OutPktsPerSec
The number of packets sent per second.
InUtilization
The percentage of the port’s bandwidth used by received traffic.
OutUtilization
The percentage of the port’s bandwidth used by sent traffic.
