Using the BayStack 350 10/100/1000 Series Switch
•
Filtering Database Identifier (FID) --- the specific filtering/forwarding
database within the BayStack 350 switch that is assigned to each VLAN. The
current version of software assigns all VLANs to the same FID. This is
referred to as Shared VLAN Learning in the IEEE 802.1Q specification.
The default configuration settings for BayStack 350 switches have all ports set as
untagged members of VLAN 1 with all ports configured as PVID = 1. Every
VLAN is assigned a unique VLAN identifier (VID) which distinguishes it from
all other VLANs. In the default configuration example shown in Figure 1-9, all
incoming packets are assigned to VLAN 1 by the default port VLAN identifier
(PVID =1). Untagged packets enter and leave the switch unchanged.

To configure VLANs, a user can reconfigure the switch ports as tagged or
untagged members of specific VLANs (see Figure 1-10 through Figure 1-13).
