permit (IPv6 access-list configuration)

Syntax Description

protocol

Name or number of an Internet protocol. It can be one of the keywords
ahp, esp, icmp, ipv6, pcp, sctp, tcp, or udp, or an integer in the range
from 0 to 255 representing an IPv6 protocol number.

source-ipv6-prefix/prefix-
length

The source IPv6 network or class of networks for which to set permit
conditions.

Note

This argument must be in the form documented in RFC 2373
where the address is specified in hexadecimal using 16-bit values
between colons.

any

An abbreviation for the IPv6 prefix ::/0.

host source-ipv6-address

The source IPv6 host address for which to set permit conditions.

This source-ipv6-address argument must be in the form documented in
RFC 2373 where the address is specified in hexadecimal using 16-bit
values between colons.

operator [port-number]

(Optional) Specify an operator that compares the source or destination
ports of the specified protocol. Operators are lt (less than), gt (greater
than), eq (equal), neq (not equal), and range (inclusive range).

If the operator is positioned after the source-ipv6-prefix/prefix-length
argument, it must match the source port.

If the operator is positioned after the destination-ipv6-prefix/prefix-length
argument, it must match the destination port.

The range operator requires two port numbers. All other operators require
one port number.

The optional port-number argument is a decimal number or the name of a
TCP or a UDP port. A port number is a number from 0 to 65535. TCP port
names can be used only when filtering TCP. UDP port names can be used
only when filtering UDP.

destination-ipv6-prefix/

prefix-length

The destination IPv6 network or class of networks for which to set permit
conditions.

This argument must be in the form documented in RFC 2373 where the
address is specified in hexadecimal using 16-bit values between colons.

host
destination-ipv6-address

The destination IPv6 host address for which to set permit conditions.

This destination-ipv6-address argument must be in the form documented
in RFC 2373 where the address is specified in hexadecimal using 16-bit
values between colons.

dscp value

(Optional) Match a differentiated services codepoint value against the
traffic class value in the Traffic Class field of each IPv6 packet header.
The acceptable range is from 0 to 63.

fragments

(Optional) Match noninitial fragmented packets where the fragment
extension header contains a nonzero fragment offset. The fragments
keyword is an option only if the protocol is ipv6 and the operator
[port-number] arguments are not specified.
