Summary of VLAN Tagging Rules
When designing a VLAN and adding ports to VLANs, the following rules
apply.
1. Each port, except for the mirror port, must belong to at least one VLAN. By
default, a port is an untagged member of the default VLAN.
2. A port can be untagged for zero or one VLAN. A port that is untagged for
a VLAN transmits frames destined for that VLAN without a VLAN tag in
the Ethernet frame.
3. A port can be tagged for zero or more VLANs. A port that is tagged for a
VLAN transmits frames destined for that VLAN with a VLAN tag,
including the VID of the VLAN.
4. A port cannot be untagged and tagged for the same VLAN.
5. The mirror port, if there is one, is not a member of any VLANs.
