NOTE: When you configure ACL logging and byte counters simultaneously, 
byte counters may display an incorrect value. Configure 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 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.
