debug netlogin XOS

[M_Nees]

Hi Folks,
how can i debug the following error message regarding mac authentiication on recent XOS 15.5.4.2 (BD8810) and solving the problem?

Reboot of the end-system does not help. Shutting down netlogin - end-system running at once over the manually configured vlan.

MSM-A: Authentication failed for Network Login MAC user 18A905BB9E50 Mac 18:A9:05:BB:9E:50 port 7:39

Here the show netlogin for this port:
show netlogin port 7:39

Port : 7:39

Port State : Enabled
Guest Vlan : Disabled

Port : 7:39

The is a very simple MAC Auth so i cannot understand why the netlogin should failed !

As a background information i run an update from XOS 12.6.2.10 to 15.5.4.2 yesterday evening.

you can debug everything on EXOS by adding events to the log filter with a lower severity, even severity debug-data/verbode/summary.For the debug severity you need to enable log debug-mode.

Hi OscarK,

this does not help because we use MAC auth with RADIUS.

Do you (or anybody else) know how i can debug this MAC Authentication process ?
