Using separate IP-pools for different Modem-groups
Hi there. I have an interesting scenario for which I am not sure there is a solution. I have a 3Com chassis running Hiper ARC (ver 5.3.105) and a number of Hiper DSP cards (ver 3.5.13). The requirement essentially is to have users assigned an IP address based on the port they dial into on the NAS. I have setup 2 separate IP-pools on the Hiper ARC, and have setup 2 different modem-groups. Each of the modem-groups is associated with a separate dial-in number. Is there a way to link each modem group to its own IP-pool on the NAS? I have seen that the either of IP-pools can be prioritized, or set up for a round-robin usage but this is essentially not going to solve the problem. I think a solution may also exist where radius assigns an IP address from separate IP pools based on the user who is connecting. Any insight into this? Cheers, Patrick Ndegwa,

Well, that could be done with the pools being in the state private, so it looks like: ---- 8-< -------------------------------- testharc> list ip poOLS IP ADDRESS POOLS Name Address Size InUse State Route Unused Priority Status mw2 217.184.217.161/28 14 0 PUBLIC AGGREGATE 0 1 ACTIVE aolip1 217.49.134.33/27 30 0 PRIVATE AGGREGATE 0 1 ACTIVE ---- 8-< -------------------------------- whereas the first pool is publicly avail for all shared services and the second one dedicated to aol ONLY the assignment happens within the RADIUS-response: ---- 8-< -------------------------------- [...] USR:USR-Framed-IP-Address-Pool-Name = "aolip1", USR:USR-Framed-IP-Address-Pool-Name = "aolip2", USR:USR-Framed-IP-Address-Pool-Name = "aolip3" ---- 8-< -------------------------------- So, make them all private and assign the pool via RADIUS. Done. Hope this helps, Oliver.

Thanks. Let me try this out.

---- 8-< --------------------------------
testharc> list ip poOLS
IP ADDRESS POOLS Name Address Size InUse State Route Unused Priority Status mw2 217.184.217.161/28 14 0 PUBLIC AGGREGATE 0 1 ACTIVE aolip1 217.49.134.33/27 30 0 PRIVATE AGGREGATE 0 1 ACTIVE
---- 8-< --------------------------------
whereas the first pool is publicly avail for all shared services and the second one dedicated to aol ONLY
the assignment happens within the RADIUS-response:
---- 8-< -------------------------------- [...] USR:USR-Framed-IP-Address-Pool-Name = "aolip1", USR:USR-Framed-IP-Address-Pool-Name = "aolip2", USR:USR-Framed-IP-Address-Pool-Name = "aolip3"
