All ports are set by default as untagged. To change port(s) to be tagged, use the <Space Bar> to uncheck - ( ) the port(s). In the above configuration, port 2 will send out tagged packets. If VLANs need to communicate with other VLANs on the network, VLAN tagging needs to be set for those ports. Also, in order for GVRP to work, VLAN tagging of those ports needs to be set.

Figure 3-30. MTU/MDU Per-Port VLAN Table

This screen allows you to only view the settings made in Switch Device Configuration menu. It shows that the switch is set to MTU/MDU VLAN mode with one uplink. If 2 uplinks are configured, ports 1 through 12 map to port 25 and ports 13 through 24 map to port 26.

NOTE:: When set to MTU/MDU Port VLAN, management over the network (non-console) can only be done through one of the uplink port. This allows for a very secure network.
