The dynamic Port VLAN List is a temporary list used in the dynamic egress function to keep track
of the VLANs and the associated users that reside off a dynamic-egress enabled port.
11.4 EXAMPLE 8, USING DYNAMIC EGRESS TO CONTROL TRAFFIC
In this simple example
attached to PCs supporting both protocols AppleTalk (809B and 80F3) and IP. Two PCs support IP
only. The AppleTalk frame traffic is to be contained so only the users running the AppleTalk
protocol can communicate with each other and not flood the network with AppleTalk frames.
However, all users are to have access to a web server connected to Port 7.

Solving the Problem
In this example, Switch 1 (S1) has already been configured with a default VLAN 0001 associated
with FID 0001 as the PVID on all ports.
The following additional steps are required to configure the switch to solve this problem.
1. Define a new VLAN (VLAN ID 2) and filtering database (FID 2) using the Device VLAN
Configuration screen.
2. Create a Layer 2 rule to associate the protocol AppleTalk 809B and 80F3 to VLAN ID 2 (VID
2) using the VLAN Classification Configuration screen. This rule is assigned to all ports.
3. Enable the dynamic egress control on VLAN 2 using the Network Tools command
(dynamic_egress enable 2).
(Figure
11-2), assume that there are four ports on the SmartSwitch device
