Usage The C-Series cannot count both packets and bytes, so when you enter the count byte
Information
options, only bytes are incremented.
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

2 0000111111000000

6 0001111000000000
7 0001111100000000
8 0001111101000000
Total Ports: 4001
Example
An ACL rule with a TCP port lt 1023 takes only one entry in the CAM:
