Enhanced Three-Speed Ethernet Controllers
15.6.4.2.7
This example demonstrates use of rule priority for determining class selector codepoints (RFC 2474) from
the IP TOS property. An example filer table is shown in
the first rule matched terminates the search, hence successively lower Diff-Serv codepoint ranges can be
compared in each step until the default (zero or greater) range is reached. By default, property 1010 (IP
TOS) takes the value 0x00 if no IP headers were recognized, therefore the table search always terminates.
15.6.4.2.8
This example demonstrates rule clusters and AND-combined entries for filing packets based on transport
protocol and well-known port numbers in a termination application. An example filer table is shown in
Table
entered only for UDP packets. A default filing rule catches the case where neither TCP nor UDP headers
are found. Each cluster compares source port number (property 1111) against a list of server ports, and files
the packets accordingly. Note that entries 1 and 2 form an AND rule for checking that the port number >=
20 and port number < 22. Entries 4 and 5 are initially set up to always fail (zero port number), and thus
comprise empty entries that can be used at a later time.
