Changing Schema for radippool

[Hitesh Vinzoda]

Hi Fajar,

We have uncommented the pool-key for NAS-PORT & CALLING-STATION-ID under sqlippool.conf and hence want the calling-station-id to be used when the lease expires/new session such that user has more chances of getting the same ip address again.

pool-key = "%{NAS-Port}"

pool-key = "%{Calling-Station-Id}"


As i said earlier, the CALLING_STATION-ID sent by LAC is so long that the first 30 characters are always unique and we end up in users competing for the same IP address i.e. duplicate IP address. so that is the reason we want to modify the schema for RADIPPOOL where field CALLING-STATION-ID is varchar(30) and we would modify is to varchar(100)

Please advise.

TIA

AFAIK the column you need to change is pool-key. But before you do
that, take a look at the comment on sqlippool.conf

## Attribute which should be considered unique per NAS
## Using NAS-Port gives behaviour similar to rlm_ippool. (And ACS)
## Using Calling-Station-Id works for NAS that send fixed NAS-Port
## ONLY change this if you know what you are doing!
pool-key = "%{NAS-Port}"
# pool-key = "%{Calling-Station-Id}"

if NAS-Port is unique, better just use that.

It shouldn't be a problem, although I'd recommend just use NAS-Port as pool-key.
