- 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 Ethernet Extender 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.
