■ Cold boot—A cold boot causes the device to reset the configuration parameters stored in non-
volatile memory to the factory defaults and then restarts the device using the restored factory
default configuration.
trapDestTable
The trapDestTable contains information about the configured trap receivers on the switch and stores this
information in non-volatile memory.To configure one or more trap receivers, see “Using the Simple
Network Management Protocol,” in Chapter 3.
Configuring RMON
RMON requires one probe per LAN segment, and standalone RMON probes traditionally have been
expensive. Therefore, the approach taken by Extreme Networks has been to build an inexpensive
RMON probe into the agent of each system. This allows RMON to be widely deployed around the
network without costing more than traditional network management. The switch accurately maintains
RMON statistics at the maximum line rate of all of its ports.
To enable or disable the collection of RMON statistics on the switch, use one of the following
commands:
enable rmon
disable rmon
By enabling RMON, the switch begins the processes necessary for collecting switch statistics. By default,
RMON is disabled. However, even in the disabled state, the switch collects etherStats and you can
configure alarms and events.
RMON saves the history, alarm, and event configurations to the configuration file. Runtime data is not
stored in the configuration file and is subsequently lost after a system restart.
Event Actions
The actions that you can define for each alarm are shown in Table 32.
To be notified of events using SNMP traps, you must configure one or more trap receivers, as described
in the section, “Using the Simple Network Management Protocol,” in Chapter 3.

log-and-trap Sends a both a log message and a trap to all trap
receivers.
