RADA authentication on 3COM switches timeouts question
Hello,
We are using RADA authentication on our LAN, and for almost every device it works flawlessly.
However, I have a question on how to handle devices that are silent for long periods of time.
( Like printers on powersave, IP-phones and some odd specialized IP-enabled equipment )
My problem is that if a port is RADA-enabled, then it will stop forwarding packets after the authentication timeout occurs. This means that ARP-requests looking for the quiet devices will not reach the device.
I have not managed to find any toggle for not shutting down forwarding on the port after this timeout.
Am I correct in my assumption, and for those devices, I will have to specify specific ports that do not use RADA authentication ?
Anyone know of a workaround ? ( For me unknown toggle, or someway to set the timeout to a really large number ? )
Regards,
Tommy
[EDIT: apologies for extra post, please see http://h30499.www3.hp.com/t5/E-Series/Wake-on-LAN-WOL-DOt1x/td-p/1163753 for almost exact same question. Keeping post due to different Subject, so hoping to increase chance of lure catching someone knowlegable [/EDIT]

Re: RADA authentication on 3COM switches timeouts question
Hello,
I would like to know if you found any solution.... Have the same problem now ... quiet devices (like printers) are loosing vlan access after some time... Tried mac-authentication quiet timers, guest-reauth timers and mac-address timer aging (because when plugged device is longer quiet there's "No MAC address on the port" when I try to type "display mac address interface ethernet x/0/x" command). Replugging network cable is not an answer for me :(, so I would appreciate any help.
Regards
Michal
