AD Usernames have gone from Control>End-Systems after turning on Netlogin MAC&dot1x authentication

[Ilya_Semenov]

Hello, everybody,

I've experienced the following issue:

1) I've configured identity-management on all switches - it allowed me to get hostnames and usernames of my Windows machines per port
2) I've found out how to send these data to Netsight>Control>Endpoint - great!
3) But I wanted even more - to get Device Family&Device Type data - and I did - now I see whether my clients are Androids, Windows or MAC OSx.

The problem is I don't get data in User Name column in End-Systems anymore. What had happened?

There were no configuration changes in identity-management!

I've noticed also that for some Apple clients I get the following error (below). I am not sure they can connect to network now( Could I fix it somehow?

Many thanks in advance,
Ilya

It's not...

You need to configure DHCP snooping.

I don't think dhcp snooping will give him usernames.

If you search for "dhcp snooping" it's the first link.

Volker, may be you've meant this kind of dhcp-snooping?

"enable ip-security dhcp-snooping ports all violation-action none"

Should it be turned of along all the way from switch to AD Domain Controller Server?

Thank you!
