NOTE – The port numbers specified in these illustrations may not directly correspond to the physical port configuration of your switch model.

When a VLAN is configured, ports are added as members of the VLAN, and the ports are defined as either tagged or untagged (see Figure 3-2through Figure 3-5).

The default configuration settings for the G8000 has all ports set as untagged members of VLAN 1 with all ports configured as PVID = 1. In the default configuration example shown in Figure 3-1, all incoming packets are assigned to VLAN 1 by the default port VLAN identifier (PVID =1).
