NOTE
To support 802.1p, the Virtual Network must have an egress VLAN assigned to it.
5.5.1.3
Virtual Network-based Priority
The virtual network-based priority mechanism is unique to Alvarion Ltd. APs. It enables you to
specify a priority level for all traffic on a virtual network. This enables users that do not have a QoS
mechanism to set traffic priority by connecting to the appropriate SSID.
If you enable a virtual network-based priority mechanism, it takes precedence regardless of the
priority mechanism supported by associated users. For example, if you set VSC-Based Low
Priority for a Virtual Network, all devices that connect to the virtual network have their traffic set at
this priority
NOTE
Reserve Vertual Network-Based Very-high priority for voice and other critical applications.
5.5.1.4
Differential Services (DiffServ)
Differential services is a method for defining IP traffic priority on a per-hop basis. The Differential
Service bits are defined in RFC2474 and are composed of the six most significant bits of the IP TOS
field. These bits define the class selector code points which maps to the appropriate traffic queue.
