Hello Dears,
I'm running S5720-56C-EI-DC with V200R010C00SPC600, and we have a 10g port as trunk port to other switch (in this case Extreme X460), nonetheless on the huawei configuration there is one qinq vlan id 4000, with ethertype default 0x8100, so, and in the other side one Extreme as ethertype set up as 0x88A8.
So, in order to get compatibility between them i set up extreme switch as ethertype 0x8100, and then I noticed that all vlans including vlans tagged over that port stopped working,
However, I thought that it could be some thing on Extreme configuration, returned the default to 0x88A8, and then started changing the ethertype on Huawei to 0x88A8, and it didn't take any effects.

I tried the same scenario over eNSP and there it worked properly just setting up "qinq protocol 88A8" into the interface Eth-trunk0 , or simply changing the ethertype default on Extreme to 0x8100, but I don't understand why in a real situation the S5720 is not working like eNSP.
Can some help me with that pls?
I've been getting a headache with that.
Cheers.
