Users Guide

ACL logs are terminated with the seq, permit, or deny commands. The threshold
range is from 1 to 100.
Defaults By default 10 ACL logs are generated if you do not specify the threshold explicitly. The default frequency at which
the ACL logs are generated is ve minutes.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) Added the support for logging of ACLs on the MXL 10/40GbE Switch IO Module
platform.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
The order option is relevant in the context of the Policy QoS feature only. For more information, refer to the
Quality of Service chapter of the Dell Networking OS Conguration Guide.
You can congure either count (packets) or count (bytes). However, for an ACL with multiple rules, you can
congure some ACLs with count (packets) and others as count (bytes) at any given time.
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (for example, gt, lt
or range) may require more than one entry. The range of ports is congured in the CAM based on bit mask
boundaries; the space required depends on exactly what ports are included in the range.
When the congured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are congured 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 congured
threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the congured 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 congure ACL logging only on ACLs that are applied to ingress interfaces; you cannot enable logging for ACLs
that are associated with egress interfaces
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.
