Configuring Remote Access
7-20 114084 Rev. A
Host Group
When you enable the DCM, the default setting (Disable) for the RMON Default
Host parameter does not create a Host configuration. To create a Host
configuration, set the RMON Default Host parameter to Enable before you enable
the DCM as described earlier in the “Acti
vating the DCM” section.
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 that 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.
Depending on the DCM memory configuration, the number of addresses can
range from 100 to 8,128. T
able 7-2 shows recommended values for this parameter.
You calculate the total memory (in bytes) that you need for the host data as
follows:
105 * Value of the RMON Max Host parameter
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.

2 to 4 2,048
5 to 8 4,096
9 to 16 8,128
