BLADE OS 5.1 Application Guide
BMD00113, September 2009 Chapter 4: VLANs 91
Figure 6 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 7 through Figure 10).
The default configuration for the GbE2c sets all ports as untagged members of VLAN 1 with all
ports configured as PVID = 1. In the default configuration example shown in Figure 6, all incoming
packets are assigned to VLAN 1 by the default port VLAN identifier (PVID =1).
Figure 7 through Figure 10 illustrate generic examples of VLAN tagging. In Figure 7, 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.
Note – The port assignments in the following figures are not meant to match the GbE2c.
