Usage
The order option is relevant in the context of the Policy QoS feature only. For
Information
more information, refer to the "Quality of Service" chapter of the Dell Networking
OS Configuration Guide.
When you use the log option, the CP processor logs details about the packets that
match. Depending on how many packets match the log entry and at what rate, the
CP may become busy as it has to log these packets' details.
The S-Series cannot count both packets and bytes; when you enter the count byte
options, only bytes are incremented.
The monitor option is relevant in the context of flow-based monitoring only. For
more information, refer to
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.
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.

Access Control Lists (ACL)
Introduced on the S6000.
Introduced on the S4820T.
Introduced on the Z9000.
Introduced on the S4810.
Added the keyword dscp.
Allows ACL control of fragmented packets for IP (Layer 3)
ACLs.
Introduced on the E-Series ExaScale.
Introduced on the S-Series.
Introduced on the C-Series.
Added support for non-contiguous mask and added the
monitor option. Deprecated the keyword established.
Expanded to include the optional QoS order priority for the
ACL entry.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.
