    Hello,

    I have a cisco 1720 that I'm trying to set up sub interfaces on. I've upgrade to ios 12.3(22) with a feature set of IP/ADSL PLUS. When I attempt to put encapsulation on the Fa0.1 I get the following:

    Router(config)#int fa0.1
    Router(config-subif)#enc
    Router(config-subif)#encapsulation ?
    % Unrecognized command

    If I do a ? it shows up as a valid option. I've read a few other posts on this topic and as they suggested I upgraded the IOS and made sure I have at least IP Plus feature set.

    If anyone is running subinterfaces on there 1720, can you please tell me what IOS your running.

    Thanks for the help,
    Will
