Specifying the Type of Service (ToS) As Match Criteria

You can discriminate higher priority traffic from lower priority traffic by

specifying the type of service as the matching criteria for the traffic filter.

To specify the type of service portion of the IP header, enter the following

command at the match prompt (for example,

box;

ip; filter-template/template1;

match)

and enter:

tos

{

<list_of_values>

}

list_of_values

is a space-delimited list. It can be any number of values from 0

through 65,535. It can also specify ranges of values. Use a dash instead of a space

to indicate a range.

Example

In this example, the router matches packets whose ToS bit is set to 1.

match/template/template1#

tos 1

match/template/template1#

Specifying TCP-Established Match Criteria

By default, the router does not filter packets on the ACK and RESET bits in the

TCP header. To allow the router to filter packets with the ACK and RESET bits,

go to the match prompt (for example,

box; ip; filter-template/template1; match)

and enter the following command:

tcp-established {on

off}

Example

In this example, the router filters packets with the ACK and RESET bits in the

TCP header turned on.

match/template/template1#

tcp-established on

match/template/template1#
