Extended Ip Acl Commands; Deny - Dell C9000 Series Reference Manual

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

deny

Configure a filter that drops IP packets meeting the filter criteria.

Commands Common to all ACL Types

number.
• Use the no deny {ip | ip-protocol-number} {source mask | any |
host ip-address} {destination mask | any | host ip-address}
command.
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.
