was trying to configure the nbar on our 6509 swtich but when I tried it
on the interface gigabitethernet 1/4 , it prompt me with this message
" NBAR 'protocol-discovery' command cannot be turned on this interface because of the following reason: Interface is a LAN port and NBAR/STILE is not supported on LAN interfaces in PFC3"

have gone through the link but I cannot find the main reason except
that the IOS version difference, my switch has IOS "Version 12.2(33)SXH"
Command and feature sets depends on the ios version only and the supported hardware which can run the image also,If you have gone through the link it says that particular ios along with harware details supports ip protcol discovery command.
