I would like use the ethertype 0x8100 for the s-vlan tag.

i am using an 3845 Router.


interface gig0/1


interface gig0/1.1

ip address x.x.x.x x.x.x.x

encapsulation dot1Q 500 second-dot1q 100

because its not possible to enter at the main-interface the command:

"dot1q tunneling ethertype 0x8100"

only ethertype 0x88a8 and 0x9100 is allowed!

so i ommited this command!

does this config work?

and which ethertype uses the router?

with infistream i could intercept the frames, which the router is sending into the lan.

so i can see now, that the frames are really double-tagged with ethertype 0x8100.
