Information
The C-Series cannot count both packets and bytes, so when you enter the
count byte
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 of 4000 - 8000 uses eight entries in the CAM:
Rule# Data Mask From To #Covered
1 0000111110100000 1111111111100000 4000 4031 32

Total Ports: 4001
Example
An ACL rule with TCP port
lt 1023
takes only one entry in the CAM:
Rule# Data Mask From To #Covered
