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).

deny udp (for IPv6 ACLs)

Configure a filter to drop user datagram protocol (UDP) packets meeting the filter criteria.
