Wireless Array
258 Configuring the Wireless Array
tagged with a priority level, i.e., a user priority tag. Since there are eight possible
user priority levels and the Array implements four wireless QoS levels, user
priorities are mapped to QoS as described below.
Figure 144. Priority Level—DSCP (DiffServ - Layer 3)
DSCP (Differentiated Services Code Point or DiffServ) uses 6 bits in the IPv4 or
IPv6 packet header, defined in RFC2474 and RFC2475. The DSCP value classifies
a Layer 3 packet to determine the Quality of Service (QoS) required. DSCP
replaces the outdated Type of Service (TOS) field.
The description below describes how both of these priority levels are mapped to
the Array’s four traffic classes.
End-to-End QoS Handling
Wired QoS - Ethernet Port:
 Egress: Outgoing wired packets are IEEE 802.1p tagged at the Ethernet
port for upstream traffic, thus enabling QoS at the edge of the network.
