We are trying to establish a 6 channel multilink connection using 3 ISDN lines. We are able to connect with 2 channels and get a 128K connection, but after we try to bring up the third channel, the connection becomes unuseable and soon disconnects. We are using a cisco router with 3 BRI interfaces, and have been working with Cisco to build a config that makes this work. They say it is possible and should work with our current config. My quetion is, has anyone else been able to do something like this? The most channels we have ever bonded has been 2, so I am not sure if there is something I am missing. Radius is authenticating the user just fine, so I don't believe it is a cause of the problem. Is this something that can be done? If so, are there any special configuration options I should be looking at?

As far as I know, the user "default" on the HARC has got a limitation of 2 channels ( show user default). So, RADIUS should not only be responsible for authentication, the VSA: USR-Max-Channels = 3 that is, from the dictionary: USR.attr USR-Max-Channels 38914 integer (1, 0) as per our merit dict, should be added to the entry. Hope this helps, Oliver. -- Was hat bei uns die geringste PopulariTAET? Oliver.Francke@mediaWays.net fon. +49-5246-80-1389 mob. +49-171-5597734 I used to have a sig, but I've stopped smoking now.

*ouch* should read 6, of course, think it's late... Good luck, Oliver. [...] -- Was hat bei uns die geringste PopulariTAET? Oliver.Francke@mediaWays.net fon. +49-5246-80-1389 mob. +49-171-5597734 I used to have a sig, but I've stopped smoking now.
I understood what you meant. I'll give it a try, and let everyone know how it goes! Thanks a bunch! -Steve On Mon, 8 Jul 2002, Oliver Francke wrote:

Setting the string USR-Max-Channels = 6 worked great.

I have done something like this in the past. We lost our backhaul ckt due to a mistaken disconnect and I setup approx 16 channels to dial long distance and route the data. 3com calls this LAN to LAN routing and has a max of 16 channels that can bond if I'm not mistaken. This was a HUGE pain in my #@@ and infact 3com told me that it could NOT be done after opening a support case with them even after pointing out that their documentation said that it COULD be done. After many, many hours of trial and error I was able to get it to work although instead of going 3com to 3com I dialed out from a cisco nas and into a 3com nas. But...it can be done.
