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.

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.

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:
•
Setting alarms for user-defined events
•
Gathering real-time and historical Ethernet statistics
•
Logging events
•
Sending traps for events
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
