teTunnelChanged

Module: TE-MIB

OID (symbolic): TE-MIB::teTunnelChanged

OID (numeric): 1.3.6.1.2.1.122.0.3

Node type: NOTIFICATION-TYPE

Description: A teTunnelChanged notification is generated when an active path on the Tunnel indexed by teTunnelName changes or a new path becomes active. The value of tePathName is the new active path.

This notification MUST be limited to at most one every minute, in case the tunnel changes quickly.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' TE-MIB::teTunnelChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.122.0.3

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:58424->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (514627128) 59 days, 13:31:11.28
