The network devices required to support multiple protocols cannot be easily grouped into a common VLAN. This may require non-standard devices to pass traffic between different VLANs in order to encompass all the devices participating in a specific protocol. This kind of configuration deprives users of the basic benefits of VLANs, including security and easy accessibility.
To avoid these problems, you can configure this switch with protocol-based VLANs that divide the physical network into logical VLAN groups for each required protocol. When a frame is received at a port, its VLAN membership can then be determined based on the protocol type being used by the inbound packets.
Use the VLAN > Protocol (Configure Protocol - Add) page to create protocol groups.
Choose either Ethernet, RFC 1042, or LLC Other as the frame type used by this protocol.
Specifies the protocol type to match. The available options are IP, ARP, RARP and IPv6. If LLC Other is chosen for the Frame Type, the only available Protocol Type is IPX Raw.
Protocol Group ID assigned to the Protocol VLAN Group. (Range: 1-2147483647)
Note: Traffic which matches IP Protocol Ethernet Frames is mapped to the VLAN (VLAN 1) that has been configured with the switch's administrative IP. IP Protocol Ethernet traffic must not be mapped to another VLAN or you will lose administrative network connectivity to the switch. If lost in this manner, network access can be regained by removing the offending Protocol VLAN rule via the console. Alternately, the switch can be power-cycled, however all unsaved configuration changes will be lost.
Use the VLAN > Protocol (Configure Interface - Add) page to map a protocol group to a VLAN for each interface that will participate in the group.
Displays a list of ports or trunks.

Trunk Identifier.
Protocol Group ID assigned to the Protocol VLAN Group. (Range: 1-2147483647)
VLAN to which matching protocol traffic is forwarded.
The priority assigned to untagged ingress traffic. (Range: 0-7, where 7 is the highest priority)
