Troubleshooting RMON
If you are not seeing the information you expected with an
rmon show
command, or if the
network management station is not collecting the desired statistics, first check that the
port is up. Then, use the
rmon show status
command to check the RMON configuration
on the GSR.
Check the following fields on the
rmon show status
command output:
1.
Make sure that RMON has been enabled on the GSR. When the GSR is booted, RMON
is off by default. RMON is enabled with the
rmon enable
command.
2.
Make sure that at least one of the RMON support levels—Lite, Standard, or
Professional—is turned on with the
rmon set lite|standard|professional
command.
3.
Make sure that RMON is enabled on the port for which you want statistics. Use the
rmon set ports
command to specify the port on which RMON will be enabled.
4.
Make sure that the control table is configured for the report that you want. Depending
upon the RMON group, default control tables may be created for all ports on the GSR.
Or, if the RMON group is not one for which default control tables can be created, you
will need to configure control table entries using the appropriate
rmon
command.
