To enable GPS output via the Line we followed this procedure
This successfully dumps the NMEA5 GPS information via telnet port 2006
To remove the login requirements on line 6 we created a group called BYPASS and applied this to the Line 6 details. This enables the locally connected device recording GPS updates to gain access without credentials. The sortware provided by the 3rd party cannot script the authencation inputs
Upon reboot the command "login authentication BYPASS" is removed from running-config line 6 even though it is still in the startup-config
AUMPURO01#show running-config | begin line 6
AUMPURO01#show startup-config | begin line 6
Any ideas on how to make this stick. Last process would be to create a macro to add the line back in the running config at startup.
That is a bug, contact Cisco TAC to have it fixed.
Or, if possible, run no aaa new-model and no login on the line.
Does the same problem occur when the modem is not connected ?
I'm trying to help someone recreate it.
We raised a case with TAC who ended up supplying us a few custom IOS's to try.
The problem is that the line 6 (GPS output) gets created by a command that is in the startup-config. Since line 6 doesn't exist until this occurs, and the protocol needs to be initalised, then this command will never be able to applied. (as line 6 doesn't exist)
The answer through TAC finally was to build a macro to add it in. We built one to add to the config 30 seconds after it can log into itself.
