Use the following information to troubleshoot Avaya WebSocket Tunnel(AWTUN) on Branch Session Manager:
To view if edge topology is enabled, run smconfig
To view AWTUN connection, run statapp. The output displays AWTUN as Tunnel.
AWTUN process runs under Linux systemd awtuns.target
Target is enabled by edgeSetup.
awtuns.target can have up to 2 services. awtun@X.service when X is 1, AWTUN service communicates with the primary System Manager. When X is 2, AWTUN service communicating with the secondary System Manager is optional.
awtun@2.service is enabled if System Manager GEO is configured.
AWTUN log messages are captured in /var/log/messages
To view the AWTUN log messages, run grep awtun /var/log/messages
awtun@1.service forwards ports for the loopback IP address 127.0.1.1 to the primary System Manager.
awtun@2.service forwards ports for the loopback IP address 127.0.1.2 to the secondary System Manager.
To view the port redirection rules, run nft list chain inet nat awtun_redirect
To view the current connections to AWTUN, run awtunstat. This utility provides a filtering option. To view the full options, run awtunstat -h
