Configuring IPv6 ACLs
Step 3b
{deny | permit} tcp
{source-ipv6-prefix/prefix-l
ength | any | host
source-ipv6-address}
[operator [port-number]]
{destination-ipv6-
prefix/prefix-length | any |
host
destination-ipv6-address}
[operator [port-number]]
[ack] [dscp value]
[established] [fin] [log]
[log-input] [neq {port |
protocol}] [psh] [range
{port | protocol}] [rst]
[routing] [sequence value]
[syn] [time-range name]
[urg]
(Optional) Define a TCP access list and the
access conditions.
Enter tcp fo
r Transmission Control Protocol. The parameters are the same as those
described in Step 3a, with these additional optional parameters:
• ack—Acknowledgment bit set.
• established—An established connection. A match occurs if the TCP datagram has
the ACK or RST bits set.
• fin—Finished bit set; no more data from sender.
• neq {port | protocol}—Matches only packets that are not on a given port number.
• psh—Push function bit set.
• range {port | protocol}—Matches only packets in the port number range.
• rst—Reset bit set.
• syn—Synchronize bit set.
• urg—Urgent pointer bit set.
Step 3c
{deny | permit} udp
{source-ipv6-prefix/prefix-l
ength | any | host
source-ipv6-address}
[operator [port-number]]
{destination-ipv6-prefix/pr
efix-length | any | host
destination-ipv6-address}
[operator [port-number]]
[dscp value] [log]
[log-input] [neq {port |
protocol}] [range {port |
protocol}] [routing]
[sequence value]
[time-range name]
(Optional) Define a UDP access list and the access conditions.
Enter udp fo
r the User Datagram Protocol. The UDP parameters are the same as those
described for TCP, except that the [operator [port]] port number or name must be a
UDP port number or name, and the established parameter is not valid for UDP.
Step 3d
{deny | permit} icmp
{source-ipv6-prefix/prefix-l
ength | any | host
source-ipv6-address}
[operator [port-number]]
{destination-ipv6-prefix/pr
efix-length | any | host
destination-ipv6-address}
[operator [port-number]]
[icmp-type [icmp-code] |
icmp-message] [dscp
value] [log] [log-input]
[routing] [sequence value]
[time-range name]
(Optional) Define an ICMP access list and the access conditions.
Enter icm
p for Internet Control Message Protocol. The ICMP parameters are the same
as those described for most IP protocols in Step 3a, with the addition of the ICMP
message type and code parameters. These optional keywords have these meanings:
• icmp-type—Enter to filter by ICMP message type, a number from 0 to 255.
• icmp-code—Enter to filter ICMP packets that are filtered by the ICMP message
code type, a number from 0 to 255.
• icmp-message—Enter to filter ICMP packets by the ICMP message type name or
the ICMP message type and code name. To see a list of ICMP message type names
and code names, use the ? key or see command reference for this release.
Step 4
end Return to privileged EXEC mode.
