Cisco PI 2.1 not correctly showing user names of wired clients with 802.1x

[Oksana Dobzhanska]

Hi,

In our network we use WS-C2960G-48TC-L switches for the end devices and WS-C3850-48T as core. User names of some wired clients are showing as "unknown" while authentication status is displayed "Authorization Succeeded", sometimes they are shown with their user names. All wireless clients are shown properly.

Please help me to resolve this issue.

 - Depends on your authentication/authorization settings for the particular ports, one obvious 'result' would be if those particular ports are not using any auth-mechanisms  (for instance).

Thanks for reply, marce1000,

I could give my settings on ports:

interface GigabitEthernet0/2
 switchport access vlan 8
 switchport mode access
 switchport nonegotiate
 no keepalive
 authentication open
 authentication order dot1x
 authentication port-control auto
 authentication violation replace
 dot1x pae authenticator
 no cdp enable
 spanning-tree portfast

They are identical for all ports. We use only user authentication method.
As I wrote earlier, sometimes PI shows user name sometimes doesn't show on the same port while authentication status is displayed "Authorization Succeeded".
