What is fbL2tpSessionsAuthPending?
This counts how many L2TP sessions are currently waiting on authentication to complete before they can proceed. A sustained or spiking count here points an admin toward a slow or unresponsive authentication backend (such as RADIUS) rather than a problem with the tunnel itself. For example, a spike in AuthPending sessions that coincides with a RADIUS server outage confirms authentication, not the L2TP layer, is the bottleneck.
