I have a 4507R-E switch and I am unable to set the encapsulation for a trunk port to 802.1Q. I have looked at the commands reference for the IOS version i have installed and it clearly states the command is as follows
switchport trunk encapsulation dot1q
When i try the same command it does not work, in fact the only options i get are for the 'switchport trunk
' command are 'allowed, native and pruning
I am running IOS version 12.2(54)
What am i missing??
