DIGITAL MultiSwitch 700 Port Based VLAN User’s Guide 4-15
On Switch 4, the only port eligible to receive Red VLAN frames is port
4, the 1Q Trunk. The frame is forwarded out port 4 with the Red
VLAN Tag header being added, as shown in Figure 4-8.

3. Switch 2 receives the tagged Red VLAN frame on port 2, as shown in
Figure 4-9. The Tag in the frame is maintained, classifying the frame
as belonging to the Red VLAN. The switch forwards the broadcast
frame out all the eligible ports, ports 3 and 4. Switch 2 simultaneously
updates its Source Address Table to reflect the location of User B (port
2).
The frame forwarded out port 3 has its Tag stripped before
transmission, and it is passed to Bridge 4 as a normal broadcast frame.
The frame that is transmitted out port 4, the 1Q Trunk, retains its
VLAN tag.
