N OTE – If a 802.1Q tagged frame is received by a port that has VLAN-tagging disabled and the
port VLAN ID (PVID) is different than the VLAN ID of the packet, then the frame is dropped
at the ingress port.

N OTE – 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 3-2 through 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).
