802.1p
To implement QoS mapping for IEEE 802.1p priority, select the Activated option and configure mapping for the 8 priority levels
defined by 802.1p priority. 802.1p user priority 0 is the lowest priority while 7 is the highest.
IP QoS
To implement QoS mapping for IP QoS, select the Activated option and configure mapping for one of two types of IP QoS, IP
ToS (Type of Service) or DiffServ:
 IP ToS assigns 0 for the lowest priority and 7 for the highest.
 DiffServ uses 64 levels with 0 being the lowest, 63 the highest. DiffServ QoS mapping requires mapping for all 64 levels.
If a level is not mapped a popup box informs the user that the level has not been assigned.
Application QoS
To implement Application QoS mapping, select the Activated option and configure queue assignment for applications. The
default applications mapping for voice and video applications set the highest priority for voice and second highest for video. The
queue assignment and RTP port ranges may be changed if desired. Queues may also be assigned for IGMP packets and
general data packets (i.e. all other traffic).
VLAN Group
QoS
To implement VLAN Group QoS mapping, select the Activated option and configure mapping for VLAN groups using the VLAN
group identification number (VID) for queue mapping. This can be used together with VLAN assignment for different virtual
connections (PVCs) for QoS mapping to the PVCs. See below for more information on how VLANs can be used on the Router.
