In environments where Local Managers contact the Control Center as needed via satellite modem, you can initiate contact from the Control Center by sending an SMS message instructing an Local Manager to start PPP.
Requirements for using this capability are:
Using the config answer editor, set the Local Manager's phone number with the number subcommand, and use the domain subcommand to set the service provider's SMS domain name. The Lantronix Control Center uses these parameters to construct a valid SMS email address, to which it can send the ppp on message to establish contact.
[admin@LantronixLM (modem)]# config answer [config answer]# number 881652234392 [config answer]# domain msg.iridium.com [config answer]# exit
[admin@LantronixLM (modem)]# config answer [config answer]# number 5125551234 [config answer]# domain txt.att.net [config answer]# exit
To activate PPP when an SMS message is received, the Local Manager must be configured to check for messages. This can be accomplished with the config monitor sms command and the built-in smsPppOn rule.
[admin@LantronixLM (modem)]# config monitor sms smsPppOn :60 Validate scheduled monitor(sms)? (This will execute the job now.) (y/n): y Job was scheduled 8: [Interval: 00:00:60 Mask: * * * * *] rulesMonitor sms none smsPppOn 60
The sequence for this feature is:
The smsPppOn rule consists of:
[admin@LantronixLM]# show rule smsPppOn rule smsPppOn action pppOn conditions sms.command equals pppOn exit exit
It can be edited to generate alerts or take additional actions.
The SMS monitor must be running for the SMS-initiated PPP feature to work.
Once the Local Manager has been configured, you can initiate a PPP connection by scheduling an "SMS Message" task from the Local Manager Summary page on the Control Center. The message will need to be delivered via email, turned into an SMS message, received by the Iridium modem, and noticed by the Local Manager before the PPP connection will be turned on. It may take an additional 30 seconds for heartbeats to resume over the out-of-band link.
