Resolving SS7 Network Related Problems
Setting the Service State of a Local Subsystem Number
To set the service state of a local subsystem number (LSSN), perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-lssn-state:ssn:serve_state command.
Where:
• ssn—MML name of the desired LSSN.
• serv_state—Desired service state. The following service states are valid:
– IS—Places an LSSN in service.
– OOS—Takes an LSSN out of service.
For example, to set the service state of an LSSN called lnp to IS, enter the set-lssn-state:lnp:IS
command.
Step 2 Verify that the state of the LSSN has changed by entering the rtrv-lssn command, as described in the
“Retrieving the State of All Local Subsystem Numbers” section on page 3-49.
Setting the Service State of an Association
To change the service state of an association, log in to the active Cisco PGW 2200 Softswitch, start an
MML session, and enter the set-association:assoc_name:serv_state[,confirm] command.
Where:
• assoc_name—MML name of the association you want to modify.
• serv_state—Service state to set. Valid values for IP links are IS, OOS, and FOOS.
• confirm—Required parameter when you are setting the service state to OOS or FOOS.
Note You cannot use this command on the standby Cisco PGW 2200 Softswitch.
For example, to set the service state of the association, assoc1, to OOS, enter the
set-association:assoc1:OOS,confirm command.
Verify that the selected association is in the proper service state by performing the procedure in the
“Retrieving the Service State for Associations” section on page 3-50.
Verifying MTP Timer Settings
When resolving signaling problems between the Cisco PGW 2200 Softswitch and an associated SS7
network element (such as an STP), you might need to verify that the MTP2 and MTP3 timer settings that
the Cisco PGW 2200 Softswitch uses conform to settings of the associated SS7 network element. Use
MML commands on the Cisco PGW 2200 Softswitch to retrieve the settings for the MTP2 and MTP3
timers. The following subsections describe methods for verifying the MTP timer settings on the Cisco
PGW 2200 Softswitch.
