HP Enterprise File Services WAN Accelerator manual Vlan

Control	Description
Additional Interface Settings	LAN Speed. Select the speed from the drop-down list to set the speed for the in-path
	LAN port. The default value is Auto.
	If your network routers or switches do not automatically negotiate the speed and duplex,
	you must manually set the speed and duplex for the primary interface.
	The speed and duplex must match (LAN and WAN) in an in-path configuration. If they do
	not match you might have a large number of errors on the interface when it is in bypass
	mode, because the switch and router are not set with the same settings.
	Duplex. Select Auto, Full, or Half from the drop-down list to set the duplex speed for the
	in-path LAN port. The default value is Auto.
	If your network routers or switches do not automatically negotiate the speed and duplex,
	you must manually set the speed and duplex for the primary interface.
	The speed and duplex must match (LAN and WAN) in an in-path configuration. If they do
	not match you might have a large number of errors on the interface when it is in bypass
	mode, because the switch and router are not set with the same settings.
	WAN Speed. Select the speed from the drop-down list to set the speed for the in-path
	WAN port. The default value is Auto.
	If your network routers or switches do not automatically negotiate the speed and duplex,
	you must manually set the speed and duplex for the primary interface.
	The speed and duplex must match (LAN and WAN) in an in-path configuration. If they do
	not match you might have a large number of errors on the interface when it is in bypass
	mode, because the switch and router are not set with the same settings.
	Duplex. Select Auto, Full, or Half from the drop-down list to set the duplex speed for the
	in-path WAN port. The default value is Auto.
	If your network routers or switches do not automatically negotiate the speed and duplex,
	you must manually set the speed and duplex for the primary interface.
	The speed and duplex must match (LAN and WAN) in an in-path configuration. If they do
	not match you might have a large number of errors on the interface when it is in bypass
	mode, because the switch and router are not set with the same settings.
	MTU. Specify the Maximum Transmission Unit (MTU) value. The MTU is the largest
	physical packet size, measured in Bytes, that a network can transmit. The default value is
	1500.
VLAN	VLAN Tag ID. If you have enabled VLAN tagging, type a numeric ID. Specify 0 to leave
	the interface untagged.
	When you specify the VLAN Tag ID for the in-path interface, all packets originating from
	the HP EFS WAN Accelerator are tagged with that identification number. This is the
	VLAN tag that the appliance uses to communicate with other HP EFS WAN Accelerators
	in your network. The VLAN Tag ID might be the same value or a different value than the
	VLAN tag used on the client. A zero (0) value specifies non-tagged (or native) VLAN.
	NOTE: When the HP EFS WAN Accelerator communicates with a client or a server it
	uses the same VLAN tag as the client or the server. If the HP EFS WAN Accelerator
	cannot determine which VLAN the client or server is in, it uses its own VLAN until it is
	able to determine that information.
	NOTE: You must also define in-path rules to apply to your VLANs. For detailed
	information, see “Setting In-Path Rules” on page 25.
