NAC to Fabric attach ERS 3600 and x435

darvid — Wed, 09 Nov 2022 18:01:57 GMT

Hi all

I've a strange issue with my settings. When ERS stack is just starting all my FA Binding with x435 are ok, but if I plug an x435, FA dosen't bind ! I must disable eap and fa on the interface and re-enable to get it running !

I've these attibutes in my NAC policy
Extreme-Dynamic-MHSA=1
FA-CLIENT-TRUST=1

Exos 31.7.1.4 patch1-36
Boss v6.5.4.013

Running-config modul fa

This was finally resolved by removing attribut Extreme-Dynamic-MHSA=1 from the rule

Switchs firmware was updated but not sure it has an impact

Exos v32.3.1.11
Boss v6.5.5.011
