CLI Guide

● eq = equal to
● neq = not equal to
● gt = greater than
● lt = less than
● range = inclusive range of ports (you must specify two ports for the port
command parameter).
port port
Enter the application layer port number. Enter two port numbers if using the range
logical operand. The range is 0 to 65535.
The following list includes some common TCP port numbers:
● 23 = Telnet
● 20 and 21 = FTP
● 25 = SMTP
● 169 = SNMP
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.
bit Enter a flag or combination of bits:
● ack: acknowledgement field
● fin: finish (no more data from the user)
● psh: push function
● rst: reset the connection
● syn: synchronize sequence numbers
● urg: urgent field
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.
Defaults Not configured.

EMC Networking OS Command Line Reference Guide.
Version Description
9.10(0.0) Introduced on the S6100–ON.
9.8(1.0) Introduced on the Z9100–ON.
9.0.2.0 Introduced on the S6000.
8.4.2.1 Introduced on the S-Series.
8.2.1.0 Introduced on the E-Series TeraScale.
7.8.1.0 Introduced on the C-Series.
7.4.1.0 Introduced on the E-Series TeraScale Added the monitor option.
Usage
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:
