“Extended IP...” Displays the name of the IP ACL.
“seq 5...” Displays the filter. If the keywords count or byte were configured in the filter,
the number of packets or bytes the filter processes is displayed at the end of the

“order 4” Displays the QoS order of priority for the ACL entry.
Example
Standard IP ACL Commands
When you create an ACL without any rule and then apply it to an interface, the ACL behavior reflects an implicit permit.
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
To drop packets with a certain IP address, configure a filter.
Syntax
deny {source | any | host {ip-address}} [count [bytes] | log] [dscp value]
[ecn value] [fragments] [monitor] [no-drop] [order]
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 {source [mask] | any | host ip-address} command.
