Hardened Managed Ethernet Switch

User’s Manual 27

RMON Groups Supported

The switch supports the following RMON MIB groups defined in RFC 2819:

- RMON Statistics Group – maintains utilization and error statistics for the

switch port being monitored.

- RMON History Group – gathers and stores periodic statistical samples from

the previous Statistics Group.

- RMON Alarm Group – allows a network administrator to define alarm

thresholds for any MIB variable. An alarm can be associated with Low

Threshold, High Threshold, or both. A trigger can trigger an alarm when the

value of a specific MIB variable exceeds a threshold, falls below a threshold,

or exceeds or falls below a threshold.

- RMON Event Group – allows a network administrator to define actions

based on alarms. SNMP Traps are generated when RMON Alarms are

triggered. The action taken in the Network Management Station depends

on the specific network management application.

Bridge Groups Supported

The switch supports the following four groups of Bridge MIB (RFC 1493):

- The dot1dBase Group – a mandatory group that contains the objects

applicable to all types of bridges.

- The dot1dStp Group – contains objects that denote the bridge’s state with

respect to the Spanning Tree Protocol. If a node does not implement the

Spanning Tree Protocol, this group will not be implemented. This group is

applicable to any transparent only, source route, or SRT bridge that

implements the Spanning Tree Protocol.

- The dot1dTp Group – contains objects that describe the entity’s transparent

bridging status. This group is applicable to transparent operation only and

SRT bridges.

- The dot1dStatic Group – contains objects that describe the entity’s

destination-address filtering status. This group is applicable to any type of

bridge which performs destination-address filtering.
