3800 no support ISL

we have a 3800 series with GigaEthernet on principal board, but not support encapsulation ISL. Is that correct?

Re: 3800 no support ISL

This is correct. ISL is cisco proprietary and was out before dot1q became the standard. Since then, ISL has been slowly phased out (can still find it on some equipment like the 3550). Hope this helps.
