Configuring Trap-Related Functions
Configuring Basic Trap Functions
traps refer to those sent by managed devices to the NMS without request. They are used to report some
urgent and important events (for example, the rebooting of managed devices).
Note that basic SNMP configuration is performed before you configure basic trap function.

Configuring Extended Trap Function
The extended trap function refers to adding “interface description” and “interface type” into the
linkUp/linkDown trap. When receiving this extended trap, NMS can immediately determine which
interface on the device fails according to the interface description and type.
