I am pretty sure you can pick up a cabletron with a console cable pretty cheap on ebay. Short a cable and have it connected and it will probably send a beacon through the network. Mismatch the speeds and see what happens. Maybe, hard code the same LAA to two nic and see if you can generate frame copy errors by using a third pc. Maybe, you can send tons of packets to the hub and generate congestion errors. Taking a pc off the ring should cause burst and maybe token errors. If you had some TR routers around you could connect to the hubs as well. The show controllers tokenring xx command will display tr errors as well. Not sure if you can have duplicate tokens because there is only one full token allowed on the ring at the same time even with early token release enabled. You'll probably need a protocol analyzer to capture the frames. You will be able to see the active monitor and the standby monitor packets and you'll be able to see the election process too. And you'll be able to see how the bit is flipped in a tr frame. Not sure what software though for TR. Sniffer would work and if you have an OS2 workstation, Navtel would work. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pierre-Alex Guanel Sent: Monday, April 15, 2002 8:54 AM To: [EMAIL PROTECTED] Subject: Token Ring Errors - Simulating [7:41497] Do you know tool(s) that can generate Bad Token ring frames, duplicate tokens, etc... ?
