People should really just use 0x88a8 - those who
aren’t, can I ask why not? Is it because you’re trying to tunnel it over a switch that
doesn’t support 802.1ad or something? I’m not saying it’s wrong, I’m > interested in
understanding the situations in which you might do this.
Some devices just don't support it, even modern kit.
We use Pseudowires to transport handovers to central ALU 7750's. The ALU 7750 drops
the packets if we use 08x88 on the handovers in the Psuedowire code. Apparently 0x8100 is
Hopefully one day they will fix it.
