Configuration guidelines

Assign different IDs to the voice VLAN, the port VLAN, and the 802.1X critical VLAN on a port, so the port can correctly process VLAN tagged incoming traffic.

You can configure only one 802.1X critical VLAN on a port. The 802.1X critical VLANs on different ports can be different.

If 802.1X clients in your network cannot trigger an immediate DHCP-assigned IP address renewal in response to a VLAN change, the 802.1X users cannot access authorized network resources immediately after an 802.1X authentication is complete. As a solution, remind the 802.1X users to release their IP addresses or repair their network connections for a DHCP reassignment after 802.1X authentication is complete. The HPE iNode client does not have this problem.
