Name – Shows the names of ACLs matching the selected type.
◆
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 on
page 361 .)
◆
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 specific protocol number (0-255).
(Options: TCP, UDP, Others; Default: Others)

to match. (Range: 0-63)
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
