Hopefully this is a very simple question to answer.
I am using IOS ver 12.4(10b) on a 3640 router with a NM-8A/S module.
When I go into the interaface configuration mode for one of the serial interfaces I cannot use and do not see the "frame-relay" command listed as one of the commands to use in the interface configuration mode.
I only see and can use the "frame-relay" commands in the gobal configuration mode.
What am I doing wrong or is there something I am missing about using the "frame-relay" commands in interface configuration mode in IOS ver 12.4?
Thanks In Advance
