IPV6 Multicast	This field displays IP Multicasting under IP Protocol version 6.
	See IP Multicast above.
802.1.Q	This IEEE specification defines a protocol for virtual LANs on
	Ethernet networks. A virtual LAN is a group of PCs that function as
	a local area network, even though the PCs may not be physically
	connected. They are commonly used to facilitate administration
	of large networks.

To block a protocol, click the appropriate check box, and click [Submit]. After you have verified that the device continues to function as expected, click the [Admin] tab. Click [Commit & Reboot] in the task bar, then click [Commit] to save your changes to the permanent memory.
