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.

Commands
deny configure a filter to drop packets.
permit configure a filter to forward packets.
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 packets protocol
type.
The platform supports both Ingress and Egress IP ACLs.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands sections.
