Table 7-10. QoS Map Criteria
Criteria
ToS value—IP precedence
ToS value—DiffServ
IP header—source or destination
IP address and protocol port
destination UDP protocol port
bridged traffic
Each QoS map entry can use only one set of criteria to match traffic. To match
another group of traffic, you must configure another entry.
Placing Traffic with a Certain ToS Value in a Low-Latency Queue.
WFQ allocates more bandwidth to traffic with higher IP precedence or Diff-
Serv values. However, the more conversation subqueues an interface accumu-
lates, the less effect a high ToS value has. Rather than relying on packets' ToS
values to grant them the bandwidth they need, you can place packets with a
certain ToS value in a low-latency queue. Use this command:
Syntax: match [dscp <value> | precedence <value>]
Use the dscp option to select DiffServ values. Valid DiffServ values are from
0 to 63; valid IP precedence values are from 0 to 7.
For example, for VoIP traffic you would enter the value set by your VoIP
devices. Usually, this is the DiffServ value for Expedited Forwarding (46).
Enter:
ProCurve(config-qos-map)# match dscp 46
You can only match the entry to one value. If you want to match more than
one value, you must configure another entry for the QoS map.
The ToS value for LLQ is always set by an application or device before the
packet arrives on the interface. Although the router can mark traffic with ToS
values, these values are used in the network to which the router forwards the
packet.
Match Command
match precedence <0-7>
match dscp <0-63>
match list <ACL listname>
match ip rtp <first port number> [<last port number>] [all]
match protocol bridge [netbeui]
