Description: A Guest VLAN is a special VLAN - typically with limited network access - on which 802.1X-unaware clients are placed after a network administrator-defined timeout. The switch follows a set of rules for entering and leaving the Guest VLAN as listed below.

When checked, the individual ports' ditto setting determines whether the port can be moved into Guest VLAN. When unchecked, the ability to move to the Guest VLAN is disabled on all ports..

What is tnNASSysGuestVlanEnable?

Globally enables or disables the Guest VLAN feature, which moves 802.1X-unaware clients into a limited-access VLAN after an admin-defined timeout; when disabled here, no port can be moved into the Guest VLAN regardless of its own per-port setting.
