@hashbang hi!

Please notice there are some limitations on VLL.

1. VLL cannot be configured on VLANIF 1;

2. the VLANIF interface configured with VLL can only correspond to one member interface;

3. the number of members in a VLAN bound to a VLL tunnel cannot be increased.

Please check if your configuration meet these limitations.
