I'm trying to setup a dot1q tunnel on a 3560X, but the option does not seem available.
Enter configuration commands, one per line. End with CNTL/Z.
SW02(config)#int gig 0/1
SW02(config-if)#sw mode ?
access Set trunking mode to ACCESS unconditionally
dynamic Set trunking mode to dynamically negotiate access or trunk mode
trunk Set trunking mode to TRUNK unconditionally
I'm sure I have seen this command visible previously so it could be configuration or VTP related, but obviously am now doubting myself.
For reference the IOS version is;
Its not an advipservices feature is it?
Thanks for your help.
according to the Configuration Guide, 802.1Q protocol tunneling is not supported on switches running the LAN base feature set.
Do you have at least an IP Base license activated (show license detail)?
Afaik ISL is not supported any more, so every trunk you set up is dot1q per default. So the encapsulation command was removed, due to only one possible option.
That's correct, but the question (as I understand it) is about 802.1q Tunneling (QinQ).
The missing command is "switchport mode dot1q-tunnel" (for more details follow the link to the Configuration Guide in my first answer).
