System resets

There is no change in how Communication Manager functions for system resets in Avaya S8300 Media
Server with a media gateway. Although translations may be present for a media gateway, Communication
Manager waits for a link to be established before attempting to access the media gateway. Upon
notification that registration has occurred, maintenance waits for the Media Module Manager to indicate
that a Media Module is present before attempting to determine which Media Modules are present.
In the event of a media gateway power failure or loss of signaling, Communication Manager detects that
the media gateway is no longer registered and, after certain conditions are satisfied, begins to remove
Media Modules (see
For Media Server resets (as opposed to media gateway resets) the media gateway attempts to re-register
with the same server, and if not successful attempts to find another Media Server. When a Media Server is
found, the Media Module discovery process ensues.

Audits

The Communication Manager audit that verifies board presence runs in order to detect missing Media
Modules after system initialization. As a result, the media gateway is audited to verify that all boards that
were originally present are still present after a reboot.

Automatic launch of Traceroute (ALT)

NOTE:
Currently, this feature operates exclusively on the S8300 Media Server.
When an Avaya G350 Media Gateway unregisters from the S8300 Media Server, the server platform
automatically sends a request to the server to execute a
traceroute is used to probe the IP address of the media gateway. In this way, if a LAN component has
failed, the traceroute

In order to keep from overloading platform processes, a traceroute cannot be executed in less than 10
seconds from the last command. The maximum rate that traceroute can be run is therefore no more than
six per minute. If the customer does not want this capability, it can be turned off by a technician. The flag
"trrte_run" is set to zero to disable the automatic execution of the command.
