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 MXL 10/40GbE Switch IO Module platform supports both ingress and egress IP ACLs.
• deny
• deny icmp
• deny tcp
• deny udp
• ip access-list extended
• permit
• permit icmp
• permit tcp
• permit udp
• seq
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]] [dscp value] [order] [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 ip-address} command.
Parameters
Note: See also Commands Common to all ACL Types and Common IP ACL Commands.
ip Enter the keyword ip to configure a generic IP access list. The keyword ip
specifies that the access list will deny all IP protocols.

protocol header.
source
Enter the IP address of the network or host from which the packets were sent.

specified in A.B.C.D format, may be either contiguous or non-contiguous.
any Enter the keyword any to specify that all routes are subject to the filter.
host ip-address Enter the keyword host followed by the IP address to specify a host IP address.
destination
Enter the IP address of the network or host to which the packets are sent.
