Command Line Reference Guide

gt = greater than
lt = less than
range = inclusive range of ports (you must specify two port
for the port parameter.)
port port
(OPTIONAL) Enter the application layer port number. Enter two port
numbers if using the range logical operand. The range is 0 to 65535.
destination
address
Enter the IPv6 address of the network or host to which the packets
are sent in the x:x:x:x::x format followed by the prefix length in the /x
format. The range is /0 to /128. The :: notation specifies successive
hexadecimal fields of zero.
count (OPTIONAL) Enter the keyword count to count packets processed
by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by
the filter.
log (OPTIONAL) Enter the keyword log to have the information kept in an
ACL log file.
monitor (OPTIONAL) Enter the keyword monitor to monitor traffic on the
monitoring interface specified in the flow-based monitoring session
along with the filter operation.
Defaults Not configured.

Command History
Version 9.0(1.3) Introduced on the S5000.
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
2 0000111111000000 1111111111000000 4032 4095 64

Total Ports: 4001
Example
An ACL rule with a TCP port lt 1023 takes only one entry in the CAM:
Rule# Data Mask From To #Covered
1 0000000000000000 1111110000000000 0 1023 1024
