Enabling Mac Authentication Multi-Vlan Mode On A Port; Configuring Mac Authentication Delay - HPE Moonshot 45Gc Security Configuration Manual

Enabling MAC authentication multi-VLAN mode
on a port
The MAC authentication multi-VLAN mode prevents an authenticated online user from service
interruption caused by VLAN changes on a port. When the port receives a packet sourced from the
user in a VLAN not matching the existing MAC-VLAN mapping, the device neither logs off the user
nor reauthenticates the user. The device creates a new MAC-VLAN mapping for the user, and traffic
transmission is not interrupted. The original MAC-VLAN mapping for the user remains on the device
until it dynamically ages out. As a best practice, configure this feature on hybrid or trunk ports.
This feature improves transmission of data that is vulnerable to delay and interference. It is typically
applicable to IP phone users.
To enable MAC authentication multi-VLAN mode on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Enable MAC authentication
multi-VLAN mode.

Configuring MAC authentication delay

When both 802.1X authentication and MAC authentication are enabled on a port, you can delay
MAC authentication so that 802.1X authentication is preferentially triggered.
If no 802.1X authentication is triggered or 802.1X authentication fails within the delay period, the port
continues to process MAC authentication.
Do not
mac-else-userlogin-secure-ext when you use MAC authentication delay. The delay does not take
effect on a port in either of the two modes. For more information about port security modes, see
"Configuring port security."
To configure MAC authentication delay:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Enable MAC authentication
delay and set the delay
timer.
