SNMP traps

A trap is an unsolicited notification sent from an agent to a management station when an event is detected. It is the opposite of polling.

Traps can send device states or port statistics, such as throughput, errors, and discards.

The following table provides a summary of available SNMP traps.

1 Only supported by HPE VC 8Gb or 16Gb 24-Port FC modules

2 The VC Module MIB has the capability to send traps when certain bandwidth and throughput utilization thresholds are reached. The counters are sampled at a fixed interval of 30 seconds and neither sample interval nor threshold values are configurable in this release. Thresholds are defined as follows:
  • Port utilization high water mark 95%

  • Port utilization low water mark 75%

  • Errors high water mark 5%

  • Errors low water mark 1%

For more information, see the description field in the associated MIB.

3 For more information, see "VC Domain Managed Status Changed traps."

IMPORTANT: During OA failover or other management network disruptions, VC SNMP traps might not reach the management station.

The VC-FC module generates connUnitPortStatusChange traps based on changes to the connUnitPortStatus element of the FA-MIB. The following table shows the mapping of connUnitPortStatusChange trap severities to the VC Domain MIB's trap severity definitions.
