Configuring the Switch

• Frame Type – Choose either Ethernet, RFC 1042, or LLC Other as the frame type
used by this protocol.
• Protocol Type – Specifies the protocol type to match. The available options are
IP, ARP, and RARP. If LLC Other is chosen for the Frame Type, the only available
Protocol Type is IPX Raw
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.
