CAUTION: Downloading firmware to an agent causes the agent to cold
restart. Refer to the Firmware Upgrade documentation or your agent
documentation for a description of the data lost when an agent is cold
restarted. The latest version of the Firmware Upgrade documentation is
available from the 3Com web site:

Standalone
RMON-2 Agents The current mode of the agent is displayed in the Agent Hardware
Maintenance dialog box. 3Com recommends that you use the RMON-2
Traffix Mode, because this sets tables on an agent to an appropriate size
for use with Traffix Manager.
As some tables created by Traffix Manager can be very large, including
RMON-2 addressMap and matrixTopN, other tables’ memory sizes are
decreased to make the best use of the agent’s resources (Table 23).
An agent set to RMON-2 Traffix Mode can still be used for network
management by LANsentry
® Manager, or any other software which uses
the RMON tables.
CAUTION: If you change the RMON-2 mode, the agent automatically
cold restarts for the changes to take effect. Refer to the Firmware
Upgrade documentation or your agent documentation for a description
of the data lost when an agent is cold restarted. The latest version of the
Firmware Upgrade documentation is available from the 3Com web site:
