The following messages are being reported in the log file.


I 04/17/20 13:56:46 05404 userTnode: Node List  event received from Switch
            Anchor Controller (SAC) 10.0.10.2.

I 04/17/20 13:56:46 05405 userTnode: Anchor controller 10.0.10.4 is down.

I 04/17/20 13:57:13 05402 userTnode: Switch Anchor Controller (SAC) is
            10.0.10.4.



Diagnostics:

When IP connectivity is lost between the SAC (Switch Anchor Controller) and the ArubaOS-Switch, the SAC event messages is reported.

In the following example, the tunnel node server state is display and then IP connectivity loss occurs. The mobility controller using the IP address 10.0.10.2 is the SAC. After IP connectivity is lost, the mobility controller using the IP address 10.0.10.4 becomes the SAC.
