Increasing Mesh Availability
Bridged frames received from a station on a LAN connected to a MAP are not modified in any way.
There is no override value for an 802.1p classification. Therefore, in bridging mode the LAN traffic
classification must be properly secured.

Frames are transmitted to the MAP LAN precisely as they are received upon the ingress to the wireless
mesh bridge.

The 1500 does not tag modify DSCP:
•
On the ingress port, the 1510 sees a DSCP marking and encapsulates the IP packet and applies the
corresponding 802.1p priority.

•
On the egress port, the 1510 decapsulates the IP packet and places it on the wire with an unmodified
DSCP marking.

For this prioritization to be effective, Ethernet devices, such as IP video cameras, must have the
capability to mark the DSCP of packets.

Client Access on Backhaul Connections
It is possible to allow client access on the 5.8 and 4.9 GHz backhaul connection while simultaneously
transmitting backhaul traffic. This feature is particularly beneficial for deployments that need to support
both 2.4 and 5GHz clients. This optional feature is turned off by default and can be enabled via the CLI
command interface with the following command.

Increasing Mesh Availability
A wireless mesh cell has similar properties to the cells used to create a cellular phone network. The
technology may define the maximum size of the cell; smaller cells can be created to cover the same
physical area, providing greater availability or capacity. This is done by adding RAPs to the cell. Just as
in the larger mesh deployment, the decision is whether to use RAPs on the same channel, as shown in

. The addition of RAPs into an area adds
capacity and resilience to that area.
