Frame Relay - FDL Command for 3900 Router T1?

Sheri Toler

Transitioning from 3825 to 3945 (OS is 15.0(1r)M13 c3900-universalk9-mz.SPA.151-4.m4). Turning on FDL on the 3825 was easy but the same command on the 3945 doesn't work. Any ideas?

You possibly have a WVIC interface on the 3945, on these there is no support for service-module commands.

You can still use FDL via loopback commands, described in documentation.

The command on the 3825 was:  service-module t1 fdl both

Doesn't seem to work on the 3945 OS.  Any ideas on how to turn on the FDL for the T1 interface?

Thanks in advance for any direction you can give on this.
