Creating an IPv6 ACL
<ipv6-source-prefix>/<prefix-length
>
The <ipv6-source-prefix>/<prefix-length> parameter specify a source prefix
and prefix length that a packet must match for the specified action (deny or
permit) to occur. You must specify the <ipv6-source-prefix> parameter in
hexadecimal using 16-bit values between colons as documented in RFC
2373. You must specify the <prefix-length> parameter as a decimal value. A
slash mark (/) must follow the <ipv6-prefix> parameter and precede the
<prefix-length> parameter.
<ipv6-destination-prefix>/<prefix-le
ngth>
The <ipv6-destination-prefix>/<prefix-length> parameter specify a
destination prefix and prefix length that a packet must match for the
specified action (deny or permit) to occur. You must specify the
<ipv6-destination-prefix> parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373. You must specify the
<prefix-length> parameter as a decimal value. A slash mark (/) must follow
the <ipv6-prefix> parameter and precede the <prefix-length> parameter
any When specified instead of the <ipv6-source-prefix>/<prefix-length> or
<ipv6-destination-prefix>/<prefix-length> parameters, matches any IPv6
prefix and is equivalent to the IPv6 prefix::/0.
host Allows you specify a host IPv6 address. When you use this parameter, you do
not need to specify the prefix length. A prefix length of all128 is implied.
tcp-udp-operator The <tcp-udp-operator> parameter can be one of the following:
• eq – The policy applies to the TCP or UDP port name or number you
enter after eq.
• gt – The policy applies to TCP or UDP port numbers greater than the
port number or the numeric equivalent of the port name you enter after
gt. Enter "?" to list the port names.
• lt – The policy applies to TCP or UDP port numbers that are less than
the port number or the numeric equivalent of the port name you enter
after lt.
• neq – The policy applies to all TCP or UDP port numbers except the port
number or port name you enter after neq.
• range – The policy applies to all TCP port numbers that are between
the first TCP or UDP port name or number and the second one you
enter following the range parameter. The range includes the port
names or numbers you enter. For example, to apply the policy to all
ports between and including 23 (Telnet) and 53 (DNS), enter the
following range 23 53. The first port number in the range must be
lower than the last number in the range.
The <source-port number> and <destination-port-number> for the
tcp-udp-operator is the number of the port.
