Standard RMON Groups

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

Table 11. Standard RMON Groups

Group	Function
Host	Records statistics about the hosts discovered on the network.
Host Top N	Gathers the top n hosts, based on a specified rate-based
	statistic. This group requires the hosts group.
Matrix	Records statistics for source and destination address pairs.
Filter	Specifies the type of packets to be matched and how and
	where the filtered packets should flow (the channel).
Packet Capture	Specifies the capture of filtered packets for a particular
	channel.

Professional RMON Groups

The Professional RMON groups correspond to the RMON 2 groups defined in RFC 2021. While RMON 1 groups allow for the monitoring of packets at the MAC layer, RMON 2 groups focus on monitoring traffic at the network and application layers.

The Professional RMON groups are shown in the table below.

Table 12. Professional RMON Groups

Group	Function
Protocol Directory	Contains a list of protocols supported by the SSR and
	monitored by RMON. See the RMON 2 Protocol Directory
	appendix in the SmartSwitch Router Command Line Interface
	Reference Manual.
Protocol Distribution	Records the packets and octets for specified ports on a per
	protocol basis.
Application Layer	Monitors traffic at the application layer for protocols defined
Host	in the protocol directory.
Network Layer Host	Monitors traffic at the network layer for protocols defined in
	the Protocol Directory.
