Figure 1 Default VLAN settings
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 2 through Figure 5 ).
The default configuration settings for the G8124 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 1 , all
incoming packets are assigned to VLAN 1 by the default port VLAN identifier (PVID =1).
Figure 2 through Figure 5 illustrate generic examples of VLAN tagging. In Figure 2 , untagged
incoming packets are assigned directly to VLAN 2 (PVID = 2). Port 5 is configured as a tagged
member of VLAN 2, and port 7 is configured as an untagged member of VLAN 2.
