The 802.1X protocol is an IEEE Standard for port-based Network Access Control and part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. Many organizations have already implemented 802.1x for PCs and laptops connecting to their enterprise network and many are now also mandating devices such as IP Phones and digital whiteboards to comply with 802.1x security standard. This blog post walks through how to setup 802.1x with EAP-TLS authentication on a Polycom VVX phone within a lab environment. Part 1 will focus on the overview, configuring the Cisco Switch and the Windows NPS RADIUS server. |
