Using HP TopTools or Other SNMP Tools To Monitor and Manage the Switch

Advanced Management: RMON and HP Extended RMON Support

Monitoring and Managing

the Switch

Caution Deleting the community named “public” disables many network management

functions (such as auto-discovery, traffic monitoring, and threshold setting).

If security for network management is a concern, it is recommended that you

change the write access for the “public” community to “Restricted”.

Note SNMP community and trap receiver configurations are activated when saved.

Rebooting the switch is not necessary unless you have also configured other

parameters that require rebooting in order to be activated. (For more on when

it is necessary to reboot, refer to “Rebooting the Switch” on page 4-12.)

Advanced Management: RMON and HP

Extended RMON Support

The switch supports RMON (Remote Monitoring) and HP Extended RMON

on all connected network segments. This allows for troubleshooting and

optimizing your network.

RMON

The following RMON groups are supported:

■ Ethernet Statistics (except the numbers of packets of different frame sizes)

■ Alarm

■ History (of the supported Ethernet statistics)

■ Event

You can access the Ethernet statistics, Alarm, and Event groups from the HP

TopTools for Hubs & Switches network management software included with

your switch.

Extended RMON

Extended RMON provides network monitoring and troubleshooting informa-

tion that analyzes traffic from a network-wide perspective. Extended RMON

notifies you about network problems and identifies the end node at fault. That

information can be used to set up RMON to study the problem more closely,

if desired. Because it is based on detailed statistical sampling, Extended

RMON lessens the load on devices and network bandwidth.
