FIGURE 5-2 L2 SWITCHING DATABASE SCREEN

The Switch can be viewed from the four perspectives in the L2 Switching DataBase screen in Figure
5-2:
VLAN & PVID Perspective see section 5.2 “VLAN & PVID Perspective”.
IP Multicast Group Perspective — see section 5.3 “IP Multicast Group Perspective”.
MAC Address Perspective see section 5.4 “MAC Address Perspective”.
Port Perspective see section 5.5 “Port Perspective”.
These four views allow a network administrator to manage and monitor VLANs and their associated
MAC addresses and ports effectively from different views.
5.2 VLAN & PVID Perspective
Packets received by the Switch will be treated in the following way with regard to the Switch's VLAN
settings:
1. When an untagged packet enters a port, it will be automatically tagged with the port's VLAN ID tag
number. Each port has a default VLAN ID setting which is user configurable (the default setting is
1). The default VLAN ID setting for each port can be changed in the PVID settings of console or
web.
2. When a tagged packet enters a port, the tag for that packet will be unaffected by the PVID Setting.
3. The packet will now proceed to the VLAN specified by it's VLAN ID tag number.
