Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 289

Extended IP ACL Commands The following commands configure extended IP ACLs, which in addition to the IP address, also examine the packet's protocol type. The C9000 supports both Ingress and Egress IP ACLs. When an ACL is created without any rule and then applied to an interface, ACL behavior reflects an implicit permit. 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. C9000 Series Syntax deny {ip | ip-protocol-number} {source mask | any | host ipaddress} {destination mask | any | host ip-address} [count [bytes]] [dscp value] [order] [monitor] [fragments] [log [interval minutes] [threshold-in-msgs [count]] [monitor] 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 any 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. Enter the keyword any to specify that all routes are subject to the filter. Access Control Lists (ACL) 289
