QoS Policy Commands
•
Only those rules that are assigned to an egress policy list are applied to egress traffic. However, certain
policy conditions and actions are not supported within an egress policy list. For example, IPv6 condi-
tions are not allowed. See the "Configuring QoS" chapter in the OmniSwitch AOS Release 6 Network
Configuration Guide for more information.
•
QoS changes DSCP and 802.1p values for traffic ingressing on an untrusted port. As a result, the new
values may not match any egress policy list rules as expected. To avoid this scenario, trust the ingress
port or configure a default ToS/DSCP/802.1p value as required.
•
If an egress policy list rule contains an 802.1p condition and the ingress port is trusted, set the default
classification of the ingress port to 802.1p. If the default classification of the ingress port is set to
DSCP, the 802.1p value of the traffic is changed per the DSCP classification and will not match the
egress 802.1p condition.
•
Egress rate limiting configured through an Ethernet Service SAP profile takes precedence over egress
rate limiting specified within a QoS egress policy list rule.
•
A rule may belong to a UNP list, the default list, and an egress policy list at the same time. By default,
a rule is assigned to a default policy list when the rule is created. If the rule is subsequently assigned to
another policy list, it still remains associated with the default list.
•
If a rule is a member of multiple policy lists but one or more of these lists are disabled, the rule is still
active in those lists that are enabled.
•
If the QoS status of a rule is disabled, then the rule is disabled for all lists even if a list to which the
policy belongs is enabled.
•
Any policy list configured through this command is not active on the switch until the qos apply
command is issued.
•
If the snapshot command is entered after the policy list command is configured, the resulting ASCII
file will include the following additional syntax for the policy list command:
from {cli | ldap | blt}
This syntax indicates how the list was created. The cli and ldap options may be changed by a user
modifying the ASCII file; however, changing this setting is not recommended. The blt option indi-
cates a built-in object, this setting is not configurable.
Examples
-> policy list unp1 type rules r1 r2 r3

-> no policy list unp1
-> policy list egr1 type egress rules r1 r2 r3
-> policy list egr1 disable
-> policy list egr1 no rules r3
-> policy list egr1 enable
-> no policy list egr1
