Usage Information
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (gt, lt, range)
may require more than one entry. The range of ports is configured in the CAM based on bitmask boundaries; the
space required depends on exactly what ports are included in the range.
Example
An ACL rule with a TCP port range 4000 - 8000 uses eight entries in the CAM:

An ACL rule with a TCP port lt 1023 takes only one entry in the CAM:
