SNR S2940-8G-v2 Switch Configuration Guide
802.1x Configuration
The access device will add the port into Guest VLAN if there is no supplicant getting authenticated
successfully in a certain stretch of time because of lacking exclusive authentication supplicant
system or the version of the supplicant system being too low.
Once the 802.1x feature is enabled and the Guest VLAN is configured properly, a port will be
added into Guest VLAN, just like Auto VLAN, if there is no response message from the supplicant
system after the device sends more authentication-triggering messages than the upper limit (EAP-
Request/Identity) from the port.
• The authentication server assigns an Auto VLAN, and then the port leaves Guest VLAN and
joins the assigned Auto VLAN. When the user becomes offline, the port will be allocated to
the specified Guest VLAN again.
