HP 2650, 802.1x, and excessive authentications
Hi,
I have HP 2650's authenticating to FreeRadius(with MySQL). The switch also gets it's port VLAN configuration from FreeRADIUS.
At the moment, I have it only doing MAC authentication over the PEAP protocol where any username/password is replaced with the MAC address of the authenticating supplicant(WinXP/2000); the MAC address is the username in the MySQL database. According to the switch and FreeRADIUS, this is working. I get Login OK in the FreeRADIUS logs and the port is configured to the correct VLAN.
However, the authentications occur every 30 seconds. This puts a large demand on the MySQL server and creates lots of log entries.
Is there a way for the switch to ignore reauthentications from the supplicants for a set amount of time?
Does anyone know if you can set the 802.1x reauthentication period on Windows?
It would be nice if a supplicant didn't try to reauthenticate for 10-15 minutes or until the interface 'flaps' (goes up then down)
Thanks,

Re: HP 2650, 802.1x, and excessive authentications
not sure if this will do what you need, but look in access security guide chapter 8 [Configuring Port-Based Access Control (802.1X)] ... ftp://ftp.hp.com/pub/networking/software/59906024-1004-Security-Guide.pdf
