Virtual ADX traps
:
Traps for alarms
The Virtual ADX software supports the following traps for alarms from RFC 1757:
Virtual ADX traps
This section presents the traps supported on devices running Virtual ADX software.
NOTE
The Traps in the VADX MIBs include the following lines in their description:
--#TYPE "Brocade Trap: Power Supply Failure"
--#SUMMARY "Power supply fails, error status %d."
--#ARGUMENTS { 0 }
--#SEVERITY MINOR
--#STATE OPERATIONAL
These lines are used by the HP OpenView network management system.
Trap Name and Number Description
newRoot
1.3.6.1.2.1.17.0.1 Indicates that the sending agent has become the new root of the
Spanning Tree. The trap is sent by a bridge soon after its election as
the new root, for example, upon expiration of the Topology Change
Timer immediately subsequent to its election.
topologyChange
1.3.6.1.2.1.17.0.2 Is sent by a bridge when any of its configured ports transitions from the
Learning state to the Forwarding state, or from the Forwarding state to
the Blocking state. The trap is not sent if a newRoot trap is sent for the
same transition.
Name, OID, and Syntax Description
alarmRisingThreshold
1.3.6.1.2.1.16.3.1.1.7
Syntax: Integer32 A threshold for the sampled statistic. This object generates an event when the current
sampled value is greater than or equal to this threshold, and the value at the last
sampling interval was less than this threshold. This object also generates an event if the
first sample after this entry becomes valid is greater than or equal to this threshold and
the associated alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3).
After a rising event is generated, another such event will not be generated until the
sampled value falls below this threshold and reaches the alarmFallingThreshold.
alarmFallingThreshold
1.3.6.1.2.1.16.3.1.1.8
Syntax: Integer32
A threshold for the sampled statistic. This object generates an event when the current
sampled value is less than or equal to this threshold, and the value at the last sampling
interval was greater than this threshold. This object also generates an event if the first
sample after this entry becomes valid is less than or equal to this threshold and the
associated alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3).
After a falling event is generated, another such event will not be generated until the
sampled value rises above this threshold and reaches the alarmRisingThreshold.
