list trace ras

Last Updated : Nov 14, 2022 |

Use list trace ras to see the RAS (registration, admission, status) messages that Communication Manager is processing between:

  • servers in a Survivable Core Server configuration

  • servers in a Survivable Remote Server/Survivable Core Server configuration

  • gatekeepers and endpoints

This can be limited to a single station or expanded to the whole system. It shows registration, keepalive, and unregistration requests.

This information is helpful when an endpoint fails to register. For example, use list trace ras for a particular endpoint, then register the endpoint. If no commands are displayed on the output screen, the gatekeeper is not receiving the message from the endpoint. Check for a network problem.

Syntax

list trace ras [  ip-address  x  |  ip-stations x  |  forced_urqs  ]
ip-address x

Shows RAS messages between the entity owning the IP address and the recipients of its messages. To monitor registration requests from the Survivable Core Server, use list trace ras ip-address to display registration requests from the Survivable Core Server and the associated response from the Main server. The list trace ras ip-address command supports the IPv6 addresses.

ip-stations x

Shows RAS messages between the gatekeeper and endpoints using the extensions specified in the command.

forced_urqs

Shows some RAS unregistration request (URQ) messages sent by the gatekeeper to force unregister endpoints. Not all gatekeeper-originated URQ messages are captured here. See the denial event log (display events, category — denial) for a complete record.
