(See VLAN Configuration Examples section)
Note:
1. When implementing overlapping VLANs, RSTP can only be enabled on one of the VLANs that is
overlapping others. RSTP can not be implemented on a VLAN that contains other VLANs within
that one. Changing anything on a VLAN will turn on RSTP on all VLANs as a precautionary
measure.
2. All N-Ring ports must be on the same tagged VLAN.
3. VID=1 has to be Admit=ALL, and cannot be tagged only.
