Description: Number of Backward transmissions
What is accL2tpTunnelStatusBackwardTransitions?
This OID counts how many times the tunnel has transitioned from an "up" state to a "down" or degraded state. This metric is important for detecting tunnel instability or flapping that disrupts services. For example, if this counter increments every hour, the tunnel is bouncing up and down, indicating an underlying problem.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.71.1.3.1.25 snmpwalk -v2c -c public <target> ACC-L2TP::accL2tpTunnelStatusBackwardTransitions
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.71.1.3.1.25.1 snmpget -v2c -c public <target> ACC-L2TP::accL2tpTunnelStatusBackwardTransitions.1
