The 60 octets are the contents of the packet. You look through the packet using the different standards for packets. Things like RFC 1700 are useful for this. > [0000]: 09 00 07 FF FF FF 00 05 02 08 09 4E 00 24 AA AA > [0010]: 03 00 00 00 80 F3 00 01 80 9B 06 04 00 01 00 05 > [0020]: 02 08 09 4E 00 FF 00 8A 00 00 00 00 00 00 00 FF > [0030]: 00 17 00 00 00 00 00 00 00 00 00 00 For instance, this packet uses an IEEE 802.3 header. 09 00 07 FF FF FF - dst addr - AppleTalk broadcast address 00 05 02 08 09 4E - src addr - 000502 - Apple Computer vendor code 00 24 - length AA - dsap AA - ssap 03 - cntl 00 00 00 - org 80 F3 - type AppleTalk AARP It is an Appletalk packet. If you don't want it to bring up the link then add a filter rule to the call filter for this connection. Pipelines come with a number of example packet filters already configured but not installed on any interfaces. One of these is an "AppleTalk Call" filter. [This filter is also explained in the User's Guide] Basically you need a Generic rule that will try to make sure the packet is an IEEE 802.3 packet and will match the Ethernet type "80f3" field. The following is an Ascend example. 20-403 AppleTalk Call Generic... Forward=No Offset=14 Length=8 Mask=ffffff000000ffff Value=aaaa0300000080f3 Compare=Equals More=No This has the disadvantage that it could [theoretically] match other packets but has the advantage that it is a single rule. To do it "better" you would need two rules that were chained together using the "More" parameter. 20-403 AppleTalk Call Generic... Forward=No Offset=0 Length=6 Mask=ffffffffffff Value=090007ffffff Compare=Equals More=Yes 20-403 AppleTalk Call Generic... Forward=No Offset=20 Length=2 Mask=ffff Value=80f3 Compare=Equals More=No ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg11461.html">Re: (ASCEND) filters</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg11459.html">Re: (ASCEND) Using wddialout to troubleshoot excessive dialing</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg11459.html">Re: (ASCEND) Using wddialout to troubleshoot excessive dialing</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg11476.html">Re: (ASCEND) Using wddialout to troubleshoot excessive dialing</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="maillist.html#11460"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd268.html#11460"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
