Configuring RMON and RMON2

Event Trap Considerations

To allow RMON to generate trap events, you must set up the SNMP manager

table. In the SNMP manager table, you add the SNMP community names that you

configured for the network management application (for example, Optivity

Analysis for Windows NT) and for the hosts on which you are running

applications. If you do not make these changes, the router will be unable to send

trap events to the network management station. See Configuring SNMP, BootP,

DHCP, and RARP Services for instructions on how to set up an SNMP manager

table.

When you set up the SNMP manager table, you can do one of the following: use

the SNMP community names that the network management application uses and

modify the trap-receiving tables on the router to use these names; or configure the

router to use specific SNMP community names and modify the network

management software to use these names.

When configuring SNMP community managers, you must assign each manager a

specific IP address; you cannot specify a wildcard for the community manager

address. Also, you must configure community managers to receive all traps, not

just generic traps. You do this by changing the Trap Types parameter in the SNMP

Manager window from Generic (the default) to All. For more information about

changing communities and community manager parameters, see Configuring

SNMP, BootP, DHCP, and RARP Services.

RMON2 MIB Groups

With RMON2, you can view traffic statistics by protocol and by application

within the protocol to obtain an enterprise view of the network. RFC 2021 defines

the function and organization of the RMON2 MIB groups.

Bay Networks implements the following seven groups in its RMON2 agent for

BayStack AN/ANH and ARN routers:

• Protocol Directory

• Protocol Distribution

• Address Mapping

• Network Layer Host

• Application Layer Host
