Configuring SNMP Services

• Collecting information for problem solving

You can conﬁgure the DCM to give management stations information they

need to solve problems. For instance, the DCM can identify the hosts on a

network that generate the most trafﬁc or errors.

Refer to “SNMP Implementation Notes,” later in this chapter, for issues you

should consider when using a DCM for RMON.

The RMON Groups

The RMON agent runs on the DCM in the 8-port ANH, and comprises a set of

MIB groups. RFC 1757 deﬁnes the function and organization of these groups.

Bay Networks implements the following groups in its RMON agent for the 8-port

ANH:

• Ethernet Statistics

• History Control

• Ethernet History

• Host

• HostTopN

• Matrix

• Filter

• Packet Capture

RMON groups contain

control

and

data

tables

. Control tables contain

control

parameters

that specify which statistics you want to access. You can view and

change many entries in a control table. Data tables contain statistics the agent

obtains, and usually you can only view entries in these tables.

Some of the groups work together to provide a particular RMON function. For

example, the History Control group and Ethernet History group together provide

the history capability in the RMON agent for the DCM.

The following sections indicate the function of each group and the tables that each

group deﬁnes. Refer to RFC 1757 for the following information:

• A list of all the parameters that appear in a control table

• The read/write status of a control parameter

• The default values for control parameters with read/write status

• A list of all the objects that appear in a data table
