TABLE 13

IPv6 ACL
arguments

Description

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-
length

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.

icmp-type

ICMP packets can be filtered by ICMP message type. The type is a number from 0 to 255.

icmp code

ICMP packets, which are filtered by ICMP message type can also be filtered by the ICMP
message code. The code is a number from 0 to 255,

icmp-message

ICMP packets are filtered by ICMP messages. Refer to

ICMP message configurations

on page

163 for a list of ICMP message types.

tcp

Indicates the you are filtering TCP packets.

udp

Indicates the you are filtering UDP packets.

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-
length

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.
