Usage Guidelines

Usage Scenario

The Simple Network Management Protocol (SNMP) is a network management standard widely used on the TCP/IP network. It uses a central computer (a network management station) that runs network management software to manage network elements. The SNMP agent reports trap messages to the network management station so that the network management station can obtain the network status in a timely manner, and the network administrator can take measures accordingly.

The display snmp-agent trap feature-name efm all command displays the following information:

Trap names supported by the EFM module. The trap names are the same as the trap names specified by the snmp-agent trap enable feature-name efm trap-name trap-name command. Each trap name corresponds to a network element abnormality.
Trap status of the EFM module. You can check whether the trap is reported based on the trap name.

Prerequisites

SNMP has been enabled. See snmp-agent.
