Hi

i have problem to assing IP to MAC based authentication (printer) on a x440 single port.
situation looks like below:

computer---
computer--- desktop switch ----- x440 switch single port
printer-------

all dot1x sesions (users) are accepted and works fine but MAC session is not.

Port : 43
Authentication : 802.1x, mac-based
Port State : Enabled
Authentication Mode : Required (Policy Enabled only)
Max Supported Users : 256 (Policy Enabled only)
Allowed Users : 128 (Policy Enabled only)
Current Users : 3 (Policy Enabled only)
------------------------------------------------
802.1x Port Configuration
------------------------------------------------
Quiet Period : 300
Supplicant Response Timeout : 120
Re-authentication : On
Re-authentication period : 0
Max Re-authentications : 3
RADIUS server timeout : 120
------------------------------------------------
MAC Mode Port Configuration
------------------------------------------------
Re-authentication period : 7200
Re-authentication : On
Authentication Delay : 120 seconds
------------------------------------------------
Netlogin Clients
------------------------------------------------

MAC IP address Authenticated Type ReAuth-Timer User
00:0f:fe:xx:xx:xx 0.0.0.0 Yes, Radius 802.1x 0 user
00:23:7d:xx:xx:xx 0.0.0.0 Yes, Radius MAC 4385 00-23-7D-XX-XX-XX
94??80:xx:xx:xx 0.0.0.0 Yes, Radius 802.1x 0 user
-----------------------------------------------
(B) - Client entry Blackholed in FDB

On NAC manager i see that user (dot1x) sesions are resolving ip addresses using radius server which is visible in request (in table), but mac sessions are not.

when i switch printer direct to x440 port, all works fine.

Please help

Regards Mark

Maybe you could post some more information...
Software version, show config netlogin, show config policy and show config aaa

Does it work if you only attach the printer behind the switch?
It could be a maximum user limit on the port?
Does the mac shows up in the fdb?
Did you enable logging?
What happend if you connect the printer (with logging enabled)?
