RMON Groups
The RMON MIB groups are defined in RFCs 1757 (RMON 1) and 2021 (RMON 2). On the XP,
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 XP.
To specify the support level for RMON groups, use the following CLI command line in Configure
mode:
To specify the ports on which RMON is to be enabled, use the following CLI command line in
Configure mode:
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.
