Usage
Information The order option is relevant in the context of the Policy QoS feature only. The
following applies:
• The seq sequence-number command is applicable only in an ACL group.
• The order option works across ACL groups that are applied on an interface via
the QoS policy framework.
• The order option takes precedence over seq sequence-number.
• If you do not configure sequence-number, the rules with the same order value
are ordered according to their configuration order.
• If you configure sequence-number, the sequence-number is used as a tie
breaker for rules with the same order.

Extended IP ACL Commands
When an ACL is created without any rule and then applied to an interface, ACL behavior reflects an
implicit permit.
The following commands configure extended IP ACLs, which in addition to the IP address, also examine
the packet’s protocol type.
The supports both Ingress and Egress IP ACLs.
