General Rules for Creating a Tagged VLAN

associates a received untagged packet to the VLAN ID that matches the PVID assigned to the port and the packet is only forwarded to those ports that are members.

Here is a summary of the rules to observe when you create a tagged VLAN:

Assign a unique name to each tagged VLAN.

Each tagged VLAN must be assigned a unique VLAN ID. If a particular VLAN spans multiple switches, each part of the VLAN on the different switches must be assigned the same VLAN ID.

A tagged port can be a member of multiple VLANs.

The AT-GS950/16PS Gigabit Ethernet Smart Switch can support up to 255 tagged VLANs per switch.
