Re: SV: Hot Standby

Where can I find more information about WCCP protocol
and in which IOS versions it is supported?
I have

IOS (tm) 3600 Software (C3640-I-M), Version 11.3(6)T, RELEASE SOFTWARE

but it is not working

guyana(config)#ip wccp enable
                  ^
% Invalid input detected at '^' marker.

guyana(config)#
