S8300/G700 System reset
There is no change in how Communication Manager functions for system resets in the S8300 Media
Server in a G700 Media Gateway. Although translations may be present for a G700, Communication
Manager waits for a link to be established before attempting to access the G700. 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 G700 power failure or loss of signaling, Communication Manager detects that the G700
is no longer registered and, after certain conditions are satisfied, begins to remove Media Modules (see
Recovery from fatal errors in the S8100 on page 128).
For Media Server resets (as opposed to G700 resets) the G700 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 a system initialization. As a result, the G700 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 a G700 Media Gateway unregisters from the S8300 Media Server, the server platform
automatically sends a request to the server to execute a
traceroute
command. The Linux program
traceroute
is used to probe the IP address of the G700. In this way, if a LAN component has failed, the
traceroute
command will discover the component. A log is kept on the platform, and can be viewed with
the Linux command
trrtelog
.
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
“torturing” is set to zero to disable the automatic execution of the command.
Results evaluation
The technician determines the time of the G700 outage and then reads the ALT log to find a similar time.
If a trace had been executed, the technician verifies that the IP addresses are the same. If there is no
matching IP address, there may be other addresses representing other Media Gateways on the same
subnet. In this case, the log entries may still be useful in tracking down a potential source of trouble.
