Usage Guidelines

Usage Scenario

The Simple Network Management Protocol (SNMP) is a network management protocol widely used on TCP/IP networks. SNMP 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 quickly determine the network status, and the network administrator can take measures accordingly.

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

Trap names supported by the VRRP module: The trap names are the same as the trap names specified by the snmp-agent trap enable feature-name vrrp [ trap-name { vrrptrapauthfailure | vrrptrapmasterdown | vrrptrapnewmaster } ] command. Each trap name corresponds to a network element abnormality.
Trap status of the VRRP module: You can check whether a trap is reported based on the trap name.

Prerequisites

SNMP agent has been enabled using the snmp-agent command.
