Configuring QoS
QoS Policy Overview

Policy Conditions
The following conditions are supported and can be combined with other conditions and/or actions:
The CLI prevents you from configuring invalid condition combinations that are never allowed; however, it
does allow you to create combinations that are supported in some scenarios. For example, you might
configure
source ip
and a
destination ip
for the same condition.
Consider the following guidelines when configuring policy conditions:
•
IPv4 and IPv6 conditions cannot be combined.
•
Source and destination MAC address conditions cannot be used in IPv6 policy rules.
•
The destination VLAN condition is only supported in multicast policy rules.
•
IP multicast traffic (not IGMP) is treated as regular traffic; QoS functionality works the same way with
this type of traffic, with the exception that the destination port condition does not apply.
•
The IP multicast condition works in combination with Layer 1, Layer 2, and Layer 3 destination condi-
tions only if these conditions specify the device that sends the IGMP report packet.
•
Source and destination parameters can be combined in Layer 2, Layer 3, and Layer 4 conditions.
•
In a given rule, ToS or DSCP can be specified for a condition with priority specified for the action.
•
Individual items and their corresponding groups cannot be combined in the same condition. For exam-
ple, a source IP address cannot be included in a condition with a source IP network group.
•
The Layer 1 destination port condition only applies to bridged traffic, not routed traffic.
•
Layer 2 and Layer 3 rules are always effected on bridged and routed traffic. As a result, combining
source or destination TCP/UDP port and IP protocol in a condition is allowed.
