Configuring for Network Management Applications

Using SNMP Tools To Manage the Switch

SNMPv1 and SNMPv2c Traps

The switches covered in this guide 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.

■Fixed or “Well-Known” Traps: A switch automatically sends fixed traps (such as “coldStart”, “warmStart”, “linkDown”, and “linkUp”) to trap receivers using the public community name. These traps cannot be redi- rected to other communities. If you change or delete the default public community name, these traps are not sent.

■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.

Configuring an SNMP Trap Receiver

Use the snmp-server host command to configure a trap receiver that can receive SNMPv1 and SNMPv2c traps, and (optionally) event log messages. When you configure a trap receiver, you specify its community membership, management station IP address, and (optionally) the type of event log messages to be sent.

If you specify a community name that does not exist—that is, has not yet been configured on the switch—the switch still accepts the trap receiver assignment. However, no traps will be sent to that trap receiver until the community to which it belongs has been configured on the switch.
