Revision A
1. A PC sends an untagged frame into access port 6 (Control VLAN) on network and power
distribution module 1. The frame is sent to other access ports on the Control VLAN (access
port 5).
2. network and power distribution module 1 tags the frame with VLAN ID = 4 and Priority = 5
and sends it through the trunk ports to network and power distribution module 2.
3. network and power distribution module 2 receives the tagged frame, and identifies the frame
belonging to the Control VLAN.
4. network and power distribution module 2 removes the tag and sends the frame to all ports
on the Control VLAN (access ports 5 and 7).
5. If network and power distribution module 1 receives multiple frames, they are tagged and
sent via trunk ports to network and power distribution module 2.
6. network and power distribution module 2 receives the frames and prioritises distribution.
