Related Commands • 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. When you use the log option, the CP processor logs details about the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets' details. NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. 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. C-Series and S-Series platforms (except the S4810) support Ingress IP ACLs only. The S4810 and Z9000 support 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. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax deny {ip | ip-protocol-number} {source mask | any | host ipaddress} {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 ipaddress} command. Parameters ip Enter the keyword ip to configure a generic IP access list. The keyword ip specifies that the access list denies all IP protocols. 226
