In networking, as in real life, if you feel that the idea of the opposite
side is false and you can not prove it, start to ask the opposite side more
questions. False ideas tend to destruct themselves very quickly. You can
start asking your customer something like this: why do you want two
encapsulations in your switched network? Is there any benefit of doing that?
See may be you get a genuine answer. If not, you will have an easy task to
convince him. Personally, I think one encapsulation is the way to go.

Subject: ISL and Dot1q Trunk
Hi,
I have to setup a new network with Cat6k (with 10 Ge interface) and Cat3550.
ISL encapsulation is not supported on 10 GE interface so we have to use
Dot1Q encapsualtion on that kind of link.
The customer wants to use both encapsulation mode (ISL on Gigabit and Dot1q
on 10 GE). I prefer to use only Dot1Q accross the whole network.
What argument can I give in order so setup this new network with only one
encapsulation method ? Does someone have a bad experience when mixing both ?
PS : I have already said to the customer that some device (Cat2950 if I'm
wrong) support only Dot1q. He told me that the only device that will be used
are cat 3550 !
Any idea or documentation is welcome !
Thanks for your help.
Bye
