of ACL logs is terminated. with the seq, permit, or deny commands. The threshold range
is from 1 to 100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at
which ACL logs must be generated. The threshold range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic that you
want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface.

Version Description
9.9(0.0) Introduced on the C9010.
9.5(0.1) Introduced on the Z9500.
9.4(0.0) Added support for flow-based monitoring on the S4810, S4820T, S6000, Z9000, and
MXL 10/40GbE Switch IO Module platforms.
9.3(0.0) Added support for logging of ACLs on the S4810, S4820T, Z9000, and MXL 10/40GbE
Switch IO Module platforms.
Usage Information
When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are configured to be recorded expires, the subsequent, fresh interval timer is started and the packet
count for that new interval commences from zero. If ACL logging was stopped previously because the configured
threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is re-enabled after the logging interval
period elapses. ACL logging is supported for standard and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs.
You can configure ACL logging only on ACLs that are applied to ingress interfaces; you cannot enable logging for
ACLs that are associated with egress interfaces.
You can activate flow-based monitoring for a monitoring session by entering the flow-based enable command in
the Monitor Session mode. When you enable this capability, traffic with particular flows that are traversing
through the ingress and egress interfaces are examined and, appropriate ACLs can be applied in both the ingress
and egress direction. Flow-based monitoring conserves bandwidth by monitoring only specified traffic instead all
traffic on the interface. This feature is particularly useful when looking for malicious traffic. It is available for Layer
2 and Layer 3 ingress and egress traffic. You may specify traffic using standard or extended access-lists. This
mechanism copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port. The
source port is the monitored port (MD) and the destination port is the monitoring port (MG).
ipv6 access-list
Configure an access list based on IPv6 addresses or protocols.
C9000 Series
Syntax
ipv6 access-list access-list-name
To delete an access list, use the no ipv6 access-list access-list-name command.
Parameters
access-list-name Enter the access list name as a string, up to 140 characters.
Defaults All access lists contain an implicit “deny any”; that is, if no match occurs, the packet is dropped.
