Configuring RMON and RMON2

B-14

300018-A Rev. 00

HostTopN Group

To save memory and increase performance, there is no default configuration for

the HostTopN group. You must create HostTopN configurations through your

RMON network management application. You can create as many HostTopN

configurations as memory permits, up to the RMON limit of 65,535

configurations.

Each HostTopN configuration requires 164 bytes. The HostTopN data requires 10

bytes of memory per host address that the Ethernet DCM detects on a segment.

You calculate the total memory (in bytes) you need for the HostTopN data as

follows:

10 * value of the RMON Max Host parameter

For information about setting the RMON Max Host parameter, see “Modifying

Default RMON MIB Group Parameters” on page 4-7.

Matrix Group

When you enable the Ethernet DCM, the default setting for the RMON Default

Matrix parameter is Disable. To create a matrix configuration, set the RMON

Default Matrix parameter to Enable (see “Modifying Default RMON MIB Group

Parameters” on page 4-7).

Some RMON network management applications expect the DCM to set up a

matrix configuration, but others set up their own configurations.

The matrix configuration requires 212 bytes. The matrix data requires

approximately 178 bytes of memory per source/destination pair that the Ethernet

DCM detects on a segment.

Note:

Before you create a HostTopN configuration, you must create a host

configuration.

Note:

The RMON agent allows you to create only one matrix configuration.

Make sure to set the RMON Default Matrix parameter according to the

expectations of the RMON network management application.
