Service Manual

port port
Enter the application layer port number. Enter two port numbers if using the range logical
operand. The range is from 0 to 65535.
destination Enter the IP address of the network or host to which the packets are sent.
mask Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in
A.B.C.D format, may be either contiguous or non-contiguous.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry.
The range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower-
order numbers have a higher priority) If you did not use the keyword order, the ACLs
have the lowest order by default (
255).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
threshold-in-msgs
count
(OPTIONAL) Enter the threshold-in-msgs keyword then a value to indicate the
maximum number of ACL logs that can be generated, exceeding which the generation of
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 five minutes.

Command History
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 Configuration Guide.
You can configure either count (packets) or count (bytes). However, for an ACL with multiple rules, you can
configure 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 configured in the CAM based on bit mask
boundaries; the space required depends on exactly what ports are included in the range.
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
