NETGEAR 8800 Chassis Switch CLI Manual enable log display The enable log display command is equivalent to the enable log target console-display command. Note that the backup-msm target is only active on the primary MSM/MM, and the primary-msm target is only active on the backup MSM/MM. Example The following command enables log messages on the current session: enable log target session enable rmon enable rmon Description Enables the collection of RMON statistics on the switch. Syntax Description This command has no arguments or variables. Default By default, RMON is disabled. However, even in the disabled state, the switch responds to RMON queries and sets for alarms and events. By enabling RMON, the switch begins the processes necessary for collecting switch statistics. Usage Guidelines The switch supports four out of nine groups of Ethernet RMON statistics. In an enabled state, the switch responds to the following four groups: • Statistics-The RMON Ethernet Statistics group provides traffic and error statistics showing packets, bytes, broadcasts, multicasts, and errors on a LAN segment or VLAN. • History-The History group provides historical views of network performance by taking periodic samples of the counters supplied by the Statistics group. The group features user-defined sample intervals and bucket counters for complete customization of trend analysis. • Alarms-The Alarms group provides a versatile, general mechanism for setting threshold and sampling intervals to generate events on any RMON variable. Both rising and falling thresholds are supported, and thresholds can be on the absolute value of a variable or its delta value. In addition, alarm thresholds may be auto calibrated or set manually. • Events-The Events group creates entries in an event log and/or sends SNMP traps to the management workstation. An event is triggered by an RMON alarm. The action taken can be configured to ignore it, to log the event, to send an SNMP trap to the receivers Chapter 8.
