For L3 OOB deployment , does any one know how the NAC agent/ActiveX/Java applet refresh the IP address for the client??

i know that In the Login Page configuration, two options need to be checked to use the ActiveX/Applet webclient to
refresh the client’s IP address:

- Use web client to detect client MAC address and Operating System
- Use web client to release and renew IP address when necessary (OOB) .

But what i need to know how the agent/ActiveX/Java applet refresh the IP address for the client???

are these programs ( agent/ActiveX/Java applet ) triggers the client machine to do that???

You're right. The applets do indeed trigger a dhcp refresh on the machines. This is to avoid bouncing the port which can be problematic when you have IP phones.

More info on this in the docs here:
