History
Version 9.3.0.0
Added support for logging of ACLs on the S4810, S4820T,
Z9000, and MXL 10/40GbE Switch IO Module platforms.
Version 9.4(0.0)
Added support for flow-based monitoring on the S4810,
S4820T, S6000, 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 reenabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is
reenabled after the logging interval period elapses. ACL logging is supported for
standard and extended IPv4 ACLs, standard and extended IPv6 ACLs, and standard
and extended 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).
