True. But I don't care about keeping the calls open, although that would be great ;). I can live with having the backup card actually go through a reboot cycle if it were necesarry. Regards, JIm Jason Kelton wrote:
I have the feeling that true failover (without the loss of calls) could be a hardware limitation of the chassis. For true failover, you wouldn't have everything run across the packetbus - you'd need to create a dual-bus to pass redundant data to in the event the first arc should fail. I mean, its possible, but prolly not within a realistic timeframe...

Maybe 3COM should look at the concept of a real Fault tolerant configuration.
It could be as easy as put a second card in and identify it as a BACKUP.
set chassis slot 2 ARC_Backup
The other ARC could mirror its config onto the backup automatically.
If the primary failed, the backup takes over as a clone of the primary.

Aaron,
The only obvious solution is to assign 2x the number of addresses to
each
ARC, or use some kind of radius-based IP address resource allocation.
Resource Assignement via Radius would appear to be more appropriate these days in any case. It means you handle the entire client-side's access and IP Assignment from within Radius.
Seems to me like a more centralised approach!
