Configuring SNMP Services

1-13

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

conﬁguration, while others set up their own conﬁgurations.

The Host conﬁguration requires 148 bytes. The Host data requires 105 bytes of

memory per host address the DCM detects on a segment.

You specify the maximum number of host addresses that appear in the Host

conﬁguration by setting the RMON Max Host parameter when you enable a

DCM. If there is not enough memory for the number of hosts you request, the

RMON agent sets the RMON Max Host parameter to the highest possible value.

The number of addresses can range from 100 to 8,128 hosts, depending on the

DCM memory conﬁguration. Table 1-4 shows recommended values for this

parameter.

You calculate the total memory (in bytes) you need for the host data as follows:

105 * Value of the RMON Max Host parameter

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.

Note: The RMON agent allows you to create only one Host conﬁguration. Be

sure to set the RMON Default Host parameter according to the expectations of

the RMON network management application.
