Hi All
I m currently working on a solution to integrate an IP Phone ( SIP100) into the SDA network . I have successfully managed to authenticate and authorize the device via 802.1x through ISE but failing to obtain an IP address from the DHCP Server .
I have verified that all the DHCP options within the relevant scope are correct but looking like the request is not even getting there .
This is a wired setup using a Cisco 9300 switches and I can confirm that the foundational network setup is correct as I have managed to successfully configure another phone model ( Ipecs) as well as some laptops and Desktop Clients .
As per the below packet capture output the authentication seems to be working fine but it appears as though the DHCP process is failing .
Can somebody please assist ?
Thanks in advance
