Cisco ISE Firefox CoA/ DHCP renewal not working

[ghermocilla]

Hi,

We are using ISE ver 2.4 and we are implementing web authentication for our guest.

Their machines are on Windows 10 and as you would know, the latest versions firefox and chrome no longer

support java plugins that's needed for the CoA/DHCP renewal.

Any possible solution for this? how ca we make it work?

This doesn't answer your question, but I would never attempt do to do the Coa/DHCP renewal Javascript method.  You are setting yourself up for failure in my opinion.  Maybe others have had consistent success with it but I haven't.  You can research the AutoSmart Port approach documented on the forums if this is on the wired side.

We had this deployed in a customers environment and it only worked with internet explorer. When they upgraded to 2.4 there was a bug that broke it even for IE.

Fixed in patch 6

I agree with Paul, macro option is the way to go. Cisco stopped reccomend the dhcp release/renew since support started depreciating in browsers.
