Learn about the SNMP traps that are supported in Extreme 9920 software.
SNMP traps are alert messages sent from a remote SNMP-enabled device to a central collector, called the SNMP manager. In more technical terms, SNMP traps are asynchronous, unpacked messages used to notify an entity in your network management system of significant issues and events.
Extreme 9920 software supports the following generic SNMP traps.
| Name | Description | When initialized |
|---|---|---|
| coldStart | A coldStart trap signifies that the sending protocol entity is reinitializing itself such that the agent's configuration or the protocol entity implementation may be altered. |
After the device is restarted. After the SNMP service on the device is restarted. |
| linkDown | A linkDown trap signifies that the sending protocol entity recognizes a failure in one of the communication links represented in the agent's configuration. | A linkDown trap is activated whenever the admin status of any
interface is changed from UP to DOWN . Example: device(config)# interface ethernet 1/2 device(config-if-eth-1/2)# shutdown The shutdown command initializes a linkDown trap. |
| linkUp | A linkUp trap signifies that the sending protocol entity recognizes that one of the communication links represented in the agent's configuration has come up. |
A linkUp trap is activated whenever the admin status of any interface is changed from DOWN to UP. Example: device(config)# interface ethernet 1/2 device(config-if-eth-1/2)# no shutdown The no shutdown command initializes a linkUp trap. |
