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:
Rule# Data Mask From To #Covered
1 0000111110100000 1111111111100000 4000 4031 32

Example
An ACL rule with a TCP port lt 1023 takes only one entry in the CAM:
Rule# Data Mask From To #Covered
