Example - Creating a Traffic Filter Without Using a Template

This example creates a traffic filter named telnet2 with no traffic filter template.

The system calculates the next highest precedence value.

ip/192.32.35.17/255.255.255.0# traffic-filter telnet2

traffic-filter/telnet2/192.32.35.17#

For information about specifying match criteria, see “Specifying Match Criteria

for IP Inbound Traffic Filters and Templates” on page 8-9

specifying the filter action, see “Specifying the Action of Inbound Traffic Filters

and Templates” on page 8-16

Specifying Match Criteria for IP Inbound Traffic Filters and

Templates

The match criteria in a filter specify which fields in the IP header of each packet

must contain the values that you specify. You can also specify certain fields in the

headers of TCP and UDP packets contained in the IP data field of IP packets.

To prepare to specify the filtering criteria, navigate to the filter template prompt

(for example,

box; ip; filter-template/telnet-in) or to the traffic filter prompt

(

box; eth 2/1; ip/192.32.35.17/255.255.255.0; traffic-filter/telnet-in) and enter:

match

You can specify match criteria for filters as described in the following sections:

Protocol type 8-13

Type of service 8-15
