RADIUS when using management addresses on multiple VLANS with Procurve.

[swaize]

I have just set up RADIUS authentication up on some switches that have multiple management addresses.

I assumed that once set up, the RADIUS auth request would come from the management address on the default VLAN. It seems however, the address it in fact originates from is seemingly chosen at random, from one of the several management addresses. Once chosen, it always comes from that address though.

Does anyone know a way to pre-select the management address the RADIUS auth request comes from?

Thanks.

If you have ProVision ASIC switches (3500/5400/6200/6600/8400) and somewhere in the K.14.xx version of code, you can select the specific IP addr that auth requests to RADIUS are sourced from:

switch(config) ip source-interface ?

This feature is not generally available on "older" switches, therefore you should have all the possible IP addr from those switches as RADIUS clients.

Perfect, we just put in 5400's. That's just the answer I was looking for!

Thanks.
