To solve the problem in this example, the users are assigned to VLANs using Switch 4 and Switch 
2 as shown in 

. Redco users are assigned to the Red VLAN and Blue Industries users 

to the Blue VLAN. The following information shows how Switch 4 and Switch 2 are configured to 
create the two VLANs to isolate the users of the two companies from one another on the network 
using the existing infrastructure.

Switch 4 is set as follows:

1. Two VLANs are added to the list of VLANs in the Static VLAN Configuration screen. An 

FDB ID is automatically assigned to each VLAN. In this example, the following VLANs are 
created:

VLAN ID 2, FDB ID 2, with a VLAN Name of Red 

VLAN ID 3, FDB ID 3, with a VLAN Name of Blue

Because the VLANs are assigned to two separate FDB IDs, the users on VLAN ID 2 and 
VLAN ID 3 cannot communicate with each other.

2. The Egress type for both VLAN ID 2, Port 1, and VLAN ID 3, Port 3, are set to UNTAGGED 

using the Static VLAN Egress Configuration screen. This means that these ports will transmit 
only untagged VLAN frames.

3. Ports 1 and 3 are configured as follows using the VLAN Port Configuration screen: 

Port 1 is set as follows:

PVID: 2
Acceptable Frame Types: ADMIT ALL FRAMES 
Ingress Filtering: ENABLED
GVRP Status: DISABLED

Port 3 is set as follows:

PVID: 3
Acceptable Frame Types: ADMIT ALL FRAMES
Ingress Filtering: ENABLED
GVRP Status: DISABLED

This causes the switch to classify all untagged frames received as belonging to the VLAN 
specified by each port PVID and to replace the previous PVID information in the port VLAN 
List with the new PVID information. This makes Port 1 part of the Red VLAN, Port 3 part of 
the Blue VLAN, and both are set to the VLAN frame format of untagged.
