•
Action – An ACL can contain any combination of permit or deny rules.
•
Source/Destination Address Type – Specifies the source or destination IP address type. Use
“Any” to include all possible addresses, “Host” to specify a specific host address in the Address
field, or “IP” to specify a range of addresses with the Address and Subnet Mask fields.
(Options: Any, Host, IP; Default: Any)
•
Source/Destination IP Address – Source or destination IP address.
•
Source/Destination Subnet Mask – Subnet mask for source or destination address. (See the
description for Subnet Mask under

•
Source/Destination Port – Source/destination port number for the specified protocol type.
(Range: 0-65535)
•
Source/Destination Port Bit Mask – Decimal number representing the port bits to match.
(Range: 0-65535)
•
Protocol – Specifies the protocol type to match as TCP, UDP or Others, where others indicates a

The control bit mask is a decimal number (for an equivalent binary bit mask) that is applied to
the control code. Enter a decimal number, where the equivalent binary bit “1” means to match
a bit and “0” means to ignore a bit. The following bits may be specified:
•
1 (fin) – Finish
•
