Version 6.5.10 Description Expanded to include the optional QoS order priority for the ACL entry. 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. Related 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 packet's 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. deny Configure a filter that drops IP packets meeting the filter criteria. 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] [no-drop] 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. Parameters ip ip-protocolnumber source mask Enter the keyword ip to configure a generic IP access list. The keyword ip specifies that the access list denies all IP protocols. Enter a number from 0 to 255 to deny based on the protocol identified in the IP protocol header. Enter the IP address of the network or host from which the packets were sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or noncontiguous. Access Control Lists (ACL) 201
