Cisco MGC Software Release 9.5(2)
Managing Signaling Channels
The following procedures are used for this feature:
• Retrieving Signaling Service States, page 35
• Retrieving the Service State for IP Routes, page 35
• Retrieving the Service State of D-Channels, page 36
• Retrieving the Service State for IP Links, page 37
• Valid Service States, page 38
Retrieving Signaling Service States
Retrieving state information about your signaling services is a task that is best performed daily. For more
information about this and other daily tasks, refer to the Cisco Media Gateway Controller Software
Release 9 Operations, Maintenance, and Troubleshooting Guide.
To retrieve information about a specific signaling service, log in to the active Cisco MGC, start an MML
session, and enter the following command:
rtrv-dest: sig_srv
Where sig_srv is the MML name of a signaling service.
The system returns a response similar to the following:
MGC-01 - Media Gateway Controller 2001-06-12 14:53:03
M RTRV
"sigsrv1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=RCNG"
For more information on the response to this command, refer to the “Valid Service States” section on
page 38.
If the destination is in a primary service state other than IS, attempt to bring it into service, as described
in the “Setting the Service State of a Signaling Service” section on page 32.
Note If the rtrv-dest MML command is entered after a switchover has occurred, the state of some of
the signaling services might be listed as undefined (UND). UND is the default state for a
signaling service when the system starts. In this instance, UND indicates that the Cisco MGC
has not received a service state message for the associated signaling service since the switchover
occurred. No user action is required.
Retrieving the Service State for IP Routes
To retrieve the service state for an individual IP route, log in to the active Cisco MGC, start an MML
session, and enter the following command:
mml>rtrv-iproute:iproute_name
For example, to retrieve the service state of an IP route called iprte1, enter the following command:
mml>rtrv-iproute:iprte1
The system returns a message similar to the following:
Media Gateway Controller 2000-03-26 20:26:18
M RTRV
