Example 4, Isolating Network Traffic According to Protocol

3.To allow all frames (except the AppleTalk frames, which will be prevented in steps 4 and 5) from being transmitted out Port 1 to Switch 3 and the network backbone, Port VLAN IDs are assigned to all switch ports using the Port Assignment screen, as follows:

•Port 1, VLAN ID: 5 for the Yellow VLAN

•Port 2, VLAN ID: 5 for the Yellow VLAN

•Port 3, VLAN ID: 5 for the Yellow VLAN

•Port 4, VLAN ID: 5 for the Yellow VLAN

•Port 5, VLAN ID: 5 for the Yellow VLAN

•Port 6, VLAN ID: 5 for the Yellow VLAN

•Port 7, VLAN ID: 5 for the Yellow VLAN

•Port 8, VLAN ID: 5 for the Yellow VLAN

4.On the Protocol VLAN Configuration screen, the VLAN ID 6 of the Grey VLAN is assigned to the AppleTalk protocol.

•VLAN ID 6, Protocol Type: AppleTalk, Status: ADD

This creates the protocol VLAN ID 6 that will handle only AppleTalk frames and enables ports to be assigned the this VLAN.

5.The AppleTalk frames must now be restricted to Ports 2 through 8 of the Yellow VLAN. On the Protocol Ports Configuration screen, All ports except Port 1 are assigned to the AppleTalk protocol, as follows:

•Port 2, VLAN ID: 6, Protocol: AppleTalk

•Port 3, VLAN ID: 6, Protocol: AppleTalk

•Port 4, VLAN ID: 6, Protocol: AppleTalk

•Port 5, VLAN ID: 6, Protocol: AppleTalk

•Port 6, VLAN ID: 6, Protocol: AppleTalk

•Port 7, VLAN ID: 6, Protocol: AppleTalk

•Port 8, VLAN ID: 6, Protocol: AppleTalk

Any AppleTalk frame received on ports 2 through 8 will be broadcast to all other ports on Switch 5 associated with the AppleTalk protocol. For example, if Port 2 received a frame with the AppleTalk protocol, Switch 5 would only transmit the frame to Ports 2, 3, 4, 6, 7, and 8.
