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 S4810 supports both Ingress and Egress IP ACLs.
NOTE: Also refer to the
sections.

Commands Common to all ACL Types
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.
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.
