Extended named ACL configuration
• max-reliability or 2 – The ACL matches packets that have the maximum reliability ToS. The
decimal value for this option is 2.
• max-throughput or 4 – The ACL matches packets that have the maximum throughput ToS. The
decimal value for this option is 4.
• min-delay or 8 – The ACL matches packets that have the minimum delay ToS. The decimal
value for this option is 8.
• min-monetary-cost or 1 – The ACL matches packets that have the minimum monetary cost
ToS. The decimal value for this option is 1.
NOTE
This value is not supported on 10 Gigabit Ethernet modules.
• normal or 0 – The ACL matches packets that have the normal ToS. The decimal value for
this option is 0.
• num – A number from 0 – 15 that is the sum of the numeric values of the options you
want. The ToS field is a four-bit field following the Precedence field in the IP header. You
can specify one or more of the following. To select more than one option, enter the decimal
value that is equivalent to the sum of the numeric values of all the ToS options you want to
select. For example, to select the max-reliability and min-delay options, enter number 10.
To select all options, select 15.
NOTE
The following QoS options are only available if a specific ICMP type is specified and cannot be used
with the any-icmp-type option set for the icmp-type parameter. See “QoS options for IP ACLs” on
page 1740 for more information on using ACLs to perform QoS.
The 802.1p-priority-matching option inspects the 802.1p bit in the ACL that can be used with
adaptive rate limiting. Enter a value from 0 – 7. For details, refer to “Inspecting the 802.1p bit in the
ACL for adaptive rate limiting” on page 1781.
The dscp-cos-mapping option maps the DSCP value in incoming packets to a hardware table that
provides mapping of each of the 0 – 63 DSCP values, and distributes them among eight traffic
classes (internal priorities) and eight 802.1p priorities.
NOTE
The dscp-cos-mapping option overrides port-based priority settings.
NOTE
The dscp-cos-mapping option is not supported for FCX devices. The dscp-cos-mapping option is
supported on FESX and FSX devices only.
The dscp-marking option enables you to configure an ACL that marks matching packets with a
specified DSCP value. Enter a value from 0 – 63. Refer to “Using an IP ACL to mark DSCP values
(DSCP marking)” on page 1742.
The dscp-matching option matches on the packet’s DSCP value. Enter a value from 0 – 63. This
option does not change the packet’s forwarding priority through the device or mark the packet.
Refer to “DSCP matching” on page 1744.
The log parameter enables SNMP traps and Syslog messages for inbound packets denied by the
ACL:
