Chapter 23: RMON Configuration Guide

RMON Groups

The RMON MIB groups are defined in RFCs 1757 (RMON 1) and 2021 (RMON 2). On the SSR, you can configure one or more levels of RMON support for a set of ports. Each level—Lite, Standard, or Professional—enables different sets of RMON groups (described later in this section). You need to configure at least one level before you can enable RMON on the SSR.

To specify the support level for RMON groups, use the following CLI command line in Configure mode:

Specifies Lite, Standard, or Professional RMON groups.

rmon set litestandardprofessional default- tables yesno

To specify the ports on which RMON is to be enabled, use the following CLI command line in Configure mode:

Specifies the ports on which RMON is enabled.

rmon set ports <port list>allports

You can configure each level of RMON support independently of each other with default tables on or off. For example, you can configure Lite with default tables on for ports et.1.(1-8) and then configure Standard with no default tables for the same ports. You cannot configure Lite on one set of ports and Standard on another set of ports.

Lite RMON Groups

This section describes the RMON groups that are enabled when you specify the Lite support level. The Lite RMON groups are shown in the table below.
