4. If the port in which the packet entered does not have membership with the VLAN specified by the
packets VLAN ID tag, the packet will be dropped. Port VLAN membership settings are changed in
the VLAN settings page.
5. If the port has membership to the VLAN specified by the packet's VLAN ID, the packet will be able
to be sent to other ports with the same VLAN ID membership.
6. Packets leaving the Switch will be either tagged or untagged depending on the setting specified
for that port’s membership properties.
The following sections describe the default VLAN, how to obtain a VLAN perspective and how to set the
PVID. For more information regarding to VLAN, please refer to appendix for more detail.
5.2.1 Default VLAN
The IEEE 802.1q standard defines VLAN ID #1 as the default VLAN. The default VLAN includes all the
ports as the factory default. The default VLAN’s egress rule restricts the ports to be all untagged, so it
can, by default, be easily used as a simple 802.1d bridging domain. The default VLAN’s domain shrinks
as untagged ports are defined in other VLANs.
5.2.2 Obtaining a VLAN Perspective
The following procedure describes how to obtain a VLAN perspective. For convenience, the VLAN ID
appears as both decimal and hexadecimal values side by side in the VLAN perspective screen.
1. From the L2 Switching DataBase screen in Figure 5-2, highlight VLAN & PVID Perspective and
press the Enter key. Highlight VLAN Settings and pres the Enter key. A VLAN perspective screen
similar to the one in Figure 5-3 appears.
