Hi Mike -
Thanks for your ideas! You actually have helped somewhat and what ever confusion there is remains my own... :-) We are running IB-Virtual Gateway and are trying to span subnets - from a server subnet that does not go through CCA to access the network to workstation subnets that do. I would really appreciate it if you could go into the details of the work around you offered. Please let me know if there's anymore specs I can offer on our set up to help. Thank you again for your help! - Sean ---- Sean Hennessey Networking and Information Security Systems Administrator The University of Portland ________________________________ From: Cisco Clean Access Users and Administrators [mailto:[EMAIL PROTECTED] On Behalf Of Mike King Sent: Monday, January 07, 2008 6:47 PM To: [email protected] Subject: Re: Clean Access and Ghost/Multicast Hi Sean, To answer your question we'd need a bit more info. To start with, I assume you are trying to multicast across multple subnets. (IE, your GhostCast server is on the other side of CCA) CCA has varying support for Multicast. What mode are you running CCA? OOB? IB-Real IP Gateway? IB-Virtual-Gateway? Clean Access IB-Real-IP-Gateway does NOT Directly support Multicast. More specifically the software router engine in CCA does not support Multicast. If you are using one of the modes where you are utilizing something else as a router (OOB, IB-Virtual-Gateway) then Multicast is dependant on your actual router, but this assumes the client is already logged in. For IB-Real-IP-Gateway, there is a technical workaround to allow multicast work. I'll go into it if you want. So Did I answer your question, or confuse you worse?

They are able to Unicast fine for one machine at a go, but when it becomes multiple it fails. We are thinking in might have to do with the switch from Unicast's specific IP addressing to Multicast's using a multicast address. Has anyone else encountered this beast and successfully slain it? We are running 4.1.3 but the problem has persisted through every flavor of Clean Access we've used.
