How to Monitor WAN Status via SNMP?

If you want to monitor the status of your WAN interface using SNMP, you can use the Object Identifier (OID) .1.3.6.1.2.1.2.2.1.8.X (where X is the interface index). This OID will help you check the operational status of your network interfaces.

Here are the steps:

1. Open your SNMP management tool or command line.
2. Use the SNMP walk command with the OID to get the status. For example:

snmpwalk -c public [IP address] .1.3.6.1.2.1.2.2.1.8.X

• where "public" is the community string
• "[IP address]" is the IP address of the SNMP-enabled device
• "X" represents the interface index, such as 1 for ge1, 2 for ge2, etc.

Example outputs:

IF-MIB::ifOperStatus.1 = INTEGER: up(1)

IF-MIB::ifOperStatus.2 = INTEGER: down(2)

The status will be shown as "up(1)" if the interface is operational and "down(2)" if it is not.
