Starting an MML Session
When a procedure requires that you start an MML session, you must perform the following steps:
Note You should run your MML sessions from the active Cisco PGW 2200 Softswitch, unless the procedure
indicates otherwise.
Step 1 Log in to the active Cisco PGW 2200 Softswitch.
Note Do not log in as UNIX root. The MML session fails if you attempt to start it as UNIX root.
Step 2 Enter the following command at the UNIX prompt:
mml
If you receive an error message indicating that sessions are already in use, enter the following command:
mml -s session number
Use any session number from 2 through 12 and repeat until you find a vacant session. After you have
successfully started an MML session, the prompt changes as shown in the following example:
machine_name
mml>

command to determine its platform state:
