Configuring IPv6 ACLs
Command or Action
[log-input] [routing] [sequence value]
[time-range name]
Step 4 {deny | permit} tcp
{source-ipv6-prefix/prefix-length | any | host
source-ipv6-address} [operator
[port-number]] {destination-ipv6-
prefix/prefix-length | any | host
destination-ipv6-address} [operator
OL-29434-01
Purpose
• The source-ipv6-prefix/prefix-length or destination-ipv6-prefix/
prefix-length is the source or destination IPv6 network or class of
networks for which to set deny or permit conditions, specified in
hexadecimal and using 16-bit values between colons (see RFC 2373).
• Enter any as an abbreviation for the IPv6 prefix ::/0.
• For host source-ipv6-address or destination-ipv6-address, enter the
source or destination IPv6 host address for which to set deny or permit
conditions, specified in hexadecimal using 16-bit values between
colons.
• (Optional) For operator, specify an operand that compares the source
or destination ports of the specified protocol. Operands are lt (less
than), gt (greater than), eq (equal), neq (not equal), and range.
If the operator follows the source-ipv6-prefix/prefix-length argument,
it must match the source port. If the operator follows the
destination-ipv6- prefix/prefix-length argument, it must match the
destination port.
• (Optional) The port-number is a decimal number from 0 to 65535 or
the name of a TCP or UDP port. You can use TCP port names only
when filtering TCP. You can use UDP port names only when filtering
UDP.
• (Optional) Enter dscp value to match a differentiated services code
point value against the traffic class value in the Traffic Class field of
each IPv6 packet header. The acceptable range is from 0 to 63.
• (Optional) Enter fragments to check noninitial fragments. This
keyword is visible only if the protocol is ipv6.
• (Optional) Enter log to cause an logging message to be sent to the
console about the packet that matches the entry. Enter log-input to
include the input interface in the log entry. Logging is supported only
for router ACLs.
• (Optional) Enter routing to specify that IPv6 packets be routed.
• (Optional) Enter sequence value to specify the sequence number for
the access list statement. The acceptable range is from 1 to
4,294,967,295.
• (Optional) Enter time-range name to specify the time range that applies
to the deny or permit statement.
(Optional) Define a TCP access list and the access conditions.
Enter tcp for Transmission Control Protocol. The parameters are the same
as those described in Step 3a, with these additional optional parameters:
• ack—Acknowledgment bit set.
