Extended named ACL configuration

•internet or 6 – The ACL matches packets that have the internetwork control precedence. If you specify the option number instead of the name, specify number 6.

•network or 7 – The ACL matches packets that have the network control precedence. If you specify the option number instead of the name, specify number 7.

•priority or 1 – The ACL matches packets that have the priority precedence. If you specify the option number instead of the name, specify number 1.

•routine or 0 – The ACL matches packets that have the routine precedence. If you specify the option number instead of the name, specify number 0.

The tos name num parameter of the ip access-listcommand specifies the IP ToS. You can specify one of the following:

•max-reliabilityor 2 – The ACL matches packets that have the maximum reliability ToS. The decimal value for this option is 2.

•max-throughputor 4 – The ACL matches packets that have the maximum throughput ToS. The decimal value for this option is 4.

•min-delayor 8 – The ACL matches packets that have the minimum delay ToS. The decimal value for this option is 8.

•min-monetary-costor 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-reliabilityand min-delayoptions, 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-typeoption set for the icmp-typeparameter. See “QoS options for IP ACLs” on page 1734 for more information on using ACLs to perform QoS.

The 802.1p-priority-matchingoption 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 1773.

The dscp-cos-mappingoption 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-mappingoption overrides port-based priority settings.

The dscp-markingoption 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 1736.
