Chapter 8 Controlling Mesh Access Points
Adding Mesh Access Points to the Mesh Network
• Ethernet VLAN tagging allows specific application traffic to be segmented within a wireless mesh
network and then forwarded (bridged) to a wired LAN (access mode) or bridged to another wireless
mesh network (trunk mode).
A typical public safety access application using Ethernet VLAN tagging is placement of video
surveillance cameras at various outdoor locations within a city. Each of these video cameras has a
wired connection to a MAP. The video of all these cameras is then streamed across the wireless
backhaul to a central command station on a wired network (see Figure 8-14).

Ethernet VLAN Tagging Guidelines
• For security reasons the Ethernet port on a mesh access point (RAP and MAP) is disabled by default.
It is enabled by configuring Ethernet Bridging on the mesh access point port.
• Ethernet bridging must be enabled on all the access points in the mesh network to allow Ethernet
VLAN tagging to operate.
