I am not able to view the IP address or Hostname for some of my end-system on the Netsight. IP Resolution is not working.
I followed the steps mentioned in the below article.
Radius accounting is enabled on the switches and SNMP is also returning form switch. With the below statement mentioned in the article i tried to configure IP-helpers.
"DHCP is also listened to so it gets to see the full hand shake of client/server. It will not participate in DHCP process but is passively listening to gain knowledge of end station identity. Make sure router's IP-helpers are configured to forward to the NAC IP address."
In my case, Firewall is the gateway/router for all my clients. Intervlan routing and DHCP release done by my Firewall which is Fortinet. I am not sure how i can configure IP helper as NAC IP address in Firewall. I f i configure IP helper then im sure that my firewall cannot release DHCP and Neither NAC also.
Anyone can help on this?
