Rmon - Nortel Passport 8600 Configuring

26 Chapter 1 Managing the switch
Read-write: members can view configuration and performance information, and
also change the configuration.
By defining a community, an agent limits access to its MIB to a selected set of
management stations. By using more than one community, the agent can provide
different levels of MIB access to different management stations.
For more information about configuring SNMP settings (including creating
community strings and setting traps) using the Device Manager, see Installing and
Using Device Manager and Configuring and Managing Security. For more
information about configuring SNMP settings using the CLI, see Getting Started
and Configuring and Managing Security.

RMON

Remote monitoring (RMON) is a management information base (MIB) or a group
of "management objects" that you use to "get" or "set" values using Simple
Network Management Protocol (SNMP). Using the CLI or Device Manager, you
enable RMON globally for devices on the switch. When RMON is enabled
globally, you then enable monitoring for individual devices on a port-by-port
basis.
RMON has four major functions:
•
•
•
•
Within Device Manager, you can set RMON alarms that relate to specific events
or variables simply by selecting these variables from a drop-down menu. You
specify events associated with alarms to be set to either trap or log-and-trap. In
turn, these alarms, when tripped, are trapped or logged.
All RMON information is viewable within both Device Manager and the CLI.
Alternatively you can use any management application that supports SNMP traps
(such as Optivity NMS

and HP OpenView*) to view RMON trap information.
