Using the Passport 8683POS Module
Alarms
Using Device Manager or the CLI, you can enable RMON globally or on a
port-by-port basis. Implementing RMON lets you set alarms relating to specific
events or variables.
Refer to Reference for the Passport 8000 Series Management Software Switching
Operations for more information on alarms.
Table 20 lists the alarms that are specific to the Passport 8683POS Module. The
alarms are listed in order of priority.
