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.
NOTE: When you congure ACL logging and byte counters simultaneously, byte counters may
display an incorrect value. Congure packet counters with logging instead.
The S-Series cannot count both packets and bytes; when you enter the count byte options, only bytes
increment.
The monitor option is relevant in the context of ow-based monitoring only. For more information, refer to
Port Monitoring.
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.
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.
