Creating Classifier Control Lists ! 13

Chapter 2: Creating Policies

! Use the following keywords to configure classification to match route-class

values:

! source-route-class—Classifies on packets associated with a route class

based on the packet’s source address; route-class range is 0–255; default is

! destination-route-class—Classifies on incoming packets associated with a

route class based on the packet’s destination address; route-class range is

0–255; default is 0.

! local true—Matches packets that are destined to a local interface.

! local false—Matches packets that are traversing the router; this is the

default setting.

For example:

host1(config)#ip classifier-list svale20 source-route-class 1 ip any any

host1(config)#ip classifier-list svale30 destination-route-class 1 ip any any tos 10

host1(config)#ip classifier-list svale40 source-route-class 1 local true ip any any

host1(config)#ip classifier-list west25 source-route-class 1 local false ip any any

In the previous example, classifier control lists match route-class values as

follows:

! svale20 matches the source address lookup route-class value of 1.

! svale30 matches the destination address lookup route-class value of 1 and

a ToS byte value of 10.

! svale40 matches the source address lookup route-class value of 1 and the

packets destined to a local interface.

! west20 matches the source address lookup route-class value of 1 and

packets that are not destined for a local interface (packets destined for

remote interfaces).

! Use the following keywords to match the ToS byte in the IP header:

! tos—Specifies the use of the whole 8 bits of the ToS byte; range is 0–255;

for example:

host1(config)#ip classifier-list tos128 ip any any tos 128

! dsfield—Specifies the use of the upper 6 bits of the ToS byte; range is

0–63; for example:

host1(config)#ip classifier-list low-drop-prec ip any any dsfield 10

! precedence—Specifies the use of the upper 3 bits of the ToS byte; range is

0–7; for example:

host1(config)#ip classifier-list priority ip any any precedence 1
