Creating an IPv6 ACL
ipv6-operator Allows you to filter the packets further by using one of the following options:
• dscp – The policy applies to packets that match the traffic class value
in the traffic class field of the IPv6 packet header. This operator allows
you to filter traffic based on TOS or IP precedence. You can specify a
value from 0 – 63.
• fragments – The policy applies to fragmented packets that contain a
non-zero fragment offset.
NOTE: This option is not applicable to filtering based on source or
destination port, TCP flags, and ICMP flags.
• routing – The policy applies only to IPv6 source-routed packets.
NOTE
This option is not applicable to filtering based on source or destination port,
TCP flags, and ICMP flags.
802.1p-priority-matching
<number>
Enables the device to match only those packets that have the same 802.1p
priorities as specified in the ACL. Enter 0 – 7.
Use this option in conjunction with traffic policies to rate limit traffic for a
specified 802.1p priority value. For details, refer to “Inspecting the 802.1p
bit in the ACL for adaptive rate limiting” on page 1781.
dscp-marking <number> Use the dscp-marking <number> parameter to specify a new QoS value to
the packet. If a packet matches the filters in the ACL statement, this
parameter assigns the DSCP value that you specify to the packet. Enter 0 –
63.
802.1p-priority-marking <number> Use the 802.1p-priority-marking <number> parameter to specify a new QoS
value to the packet (0-7). If a packet matches the filters in the ACL
statement, the following actions happen:
• On FSX devices, this parameter assigns the 802.1p priority that you
specify to the packet.
• On all platforms other than FSX, this parameter assigns the priority that
you specify to the 802.1p priority and the internal priority.
internal-priority-marking <number> Use the internal-priority-marking <number> parameter to specify a new QoS
value to the packet (0-7). If a packet matches the filters in the ACL
statement, the following actions happen:
• On FSX devices, this parameter assigns the internal priority that you
specify to the packet.
• On all platforms other than FSX, this parameter assigns the priority that
you specify to the internal priority and the 802.1p priority.
NOTE: On all platforms other than FSX, configuring 802.1p-priority-marking
alone or configuring both 802.1p-priority-marking and
internal-priority-marking has the same functionality. That is, it
assigns the priority that you specify to the 802.1p priority and the
internal priority.
