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 have been applied on an
interface via the QoS policy framework.
• The order option takes precedence over seq sequence-number.
• If sequence-number is not configured, the rules with the same order value are
ordered according to their configuration order.
• If sequence-number is configured, the sequence-number is used as a tie
breaker for rules with the same order.

deny — configures a filter to drop packets.
permit — configures 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 packet’s protocol type.
The Z9000 supports both Ingress and Egress IP ACLs.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands
sections.
deny
Configure a filter that drops IP packets meeting the filter criteria.
Z9000
Syntax
deny {ip | ip-protocol-number} {source mask | any | host ip-
address} {destination mask | any | host ip-address} [count
[byte] | log] [dscp value] [order] [monitor] [fragments]
To remove this filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’s
sequence number.
• Use the no deny {ip | ip-protocol-number} {source mask | any |
host ip-address} {destination mask | any | host ip-address}
command.
