Chapter 4 Managing the Passport 8683POS Module 77

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.
