49.3 Media Gateway Board's Debug Recording Traces
and Logging
Media Gateway Board Debug Recording Traces is a powerful debugging tool that
provides ability to capture traffic being handled by the specific Media Gateway board.
It may be used for analyzing different inter-op scenarios or specific Media Gateway
board malfunctions.
The tool enables forwarding of the specific packets being handled by the Media
Gateway board to the user-specified remote IP address. The remote IP address may
belong to one of the following:
External PC
Standby SC board
Flexible user-defined filtering rules may be applied to select traffic to be forwarded.
For example, it is possible to select traffic between the Media Gateway board and
specific remote Media Gateway. Or, alternatively, select traffic that belongs to the
specific call. Multiple filtering rules may be applied simultaneously.
Forwarded traffic may be recorded on the External PC or Standby SC board via any
network sniffer application.
When Debug Recording Traces are forwarded to the External PC, the WireShark
application is recommended both for the trace collection and analysis. It may be
downloaded from 'http://www.wireshark.org.' 'http://www.wireshark.org.
