We have 6500 with IOS version "c6sup22-jsv-mz.121-26.E8.bin". 6500 has one 8-port GBIC blade and a few 48-port GE-TX blades.


On GBIC port "switchport trunk encapsulation dot1q/isl" can be configured. But on GE-TX, there is no command opiton for that.


How can we cofigure trunking on GE-TX port?


Thanks,

Hi Friend,


I believe you are talking about 6148-GE-TX or 6548-GE-TX line cards correct?


If that is correct they do not support ISL trunking and only support dot1q trunking and is the reason they do not have this command available so by default it always take dot1q trunking once you configure command "switchport mode trunk"


You can have a look at this link an serach for "keyword" isl

Hi Ankur,


Thanks for your reply.

Yes, We are using 6148-GE-TX card.


So, on these ports, "swithport mode trunk" is equavilant to "switchport trunk encapsulation dot1q + switchport mode trunk".


Thanks,

Hi


And just to add to ankur's post check that u configured the port as layer 2 port.by issuing swithcport command under u r interface.


Thanks
