I have a Switch type WS-C2950T-48-SI with a software version 12.1(22)EA4-C2950-I6Q4L2-M.
In this Switch i need to apply an extended ACL to an interface for a PC that was just Added.
Now, i'm able to add the ACL's in global configuration mode, but when i go to any interface and try to give the command "ip access-group ...", but my switch does not recognise this command. When i give "ip ?" it does not show the command Access-Group to any interface.
Could this be an IOS upgrade problem or am I missing something?
