vlan 1002 and 1003 only worked when i comment "bridge-vlan-aware yes", otherwise it will not ping nodes each other.

on a hunch - does it work with vlan-aware enabled but with the mtu 9000 setting removed?

it does not work even though i remove mtu 9000.

it dose work if vlan number less than 127 with bridge-vlan-aware enabled.

bridge-ports bond0

bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

* check `dmesg` for messages related to your NIC
* try to disable all offloading features of the NIC with ethtool (ethtool -k enp94s0 should show which ones are available)

The issue might be that vlan-offloading in the NIC is limited to fewer VLANs (you try to configure it for 4092 vlan's some NICs can only handle 127)
It might work to disable the offloading and do vlan tagging and untagging in software

I hope this helps!
