SNMPv1 and SNMPv2c Traps

The switches support the following functionality from earlier SNMP versions (SNMPv1 and SNMPv2c):
  • Trap receivers: A trap receiver is a management station to which the switch sends SNMP traps and (optionally) event log messages sent from the switch. From the CLI you can configure up to ten SNMP trap receivers to receive SNMP traps from the switch.
  • Default Traps: A switch automatically sends default traps to trap receivers using the configured community name. You have to configure and supply the community name to use in the trap-receiver config, there is no default. Use the snmp-server host <IP_ADDRESS> community "<COMMUNITY_NAME>" command to configure a community name and the snmp-server host <IP_ADDRESS> community "<COMMUNITY_NAME>" trap-level [all | critical | not-info | debug | none] command to set the level of traps to send to the community.
  • Thresholds: A switch automatically sends all messages created when a system threshold is reached to the network management station that configured the threshold, regardless of the trap receiver configuration.
