By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.
Use the monitor option only when you are using flow-based monitoring. For
more information, refer to the Port Monitoring chapter of the Z9500 Configuration
Guide.

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 Z9500 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
Configure a filter that drops IP packets meeting the filter criteria.
Z9500
Syntax deny {ip | ip-protocol-number} {source mask | any | host ip-
address} {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 Enter the keyword ip to configure a generic IP access list.
The keyword ip specifies that the access list denies all IP
protocols.
