Switch dies

Hello everyone, just a dumb question. My switch is configured for vmps and freeradius and I'm playing with dynamic assignation of vlans. Vmps, when instructs the switch to place a client in a determined vlan, if that vlan doesn't exist in the switch, the switch just blocks access and continues with its normal operation. But, if I try the same with FreeRadius, when FreeRadius gives the vlan back (this vlan doesn't exist in the switch either), the switch freezes and I can't use it anymore until I restart it. Why is this behaviour? Thanks _________________________________________________________________ Don't just search. Find.
