HP Enterprise File Services WAN Accelerator manual Ftp

Control	Description
Advanced Options	VLAN Tag ID. Select the VLAN identification number from the drop-down list to set
	the VLAN tag identification number (VLAN ID). All specifies the rule applies to all
	VLANs; Untagged specifies the rule applies to non-tagged connections.
	The HP EFS WAN Accelerator supports VLAN 802.1q. To configure VLAN tagging you
	perform the following tasks:
	• You configure in-path rules to apply to all VLANs or to a specific VLAN. By default,
	rules apply to all VLAN values unless you specify a particular VLAN ID. Pass-through
	traffic maintains any pre-existing VLAN tagging between the LAN and WAN
	interfaces.
	• You set the in-path interfaces, VLAN tag IDs to define the VLAN tag that the HP EFS
	WAN Accelerator uses to communicate with other HP EFS WAN Accelerator. For
	detailed information, see “Setting In-Path Interfaces” on page 54.
	Optimization Policy. Optionally, if you have selected an Auto-Discoveryor Fixed
	Target rule, you can configure the following types of optimization policies:
	• Normal. Perform Lempel-Ziv (LZ) compression and Scalable Data Referencing
	(SDR).
	• SDR-Only. Perform SDR; do not perform LZ compression.
	• Compression-Only. Perform LZ compression; do not perform SDR.
	• None. Do not perform SDR or LZ compression.
	Setting an optimization policy allows you more flexibility in applying optimization
	techniques. For example, if you have a network that requires 45 Mbps or higher with
	abundant bandwidth, you do not need to perform LZ compression to obtain maximum
	optimization of data. Turning off LZ compression also increases throughput on large
	bandwidth networks.
	To configure optimization policies for the File Transfer Protocol (FTP) data channel,
	define an in-path rule with the destination port 20 and set its optimization policy. Setting
	QoS for port 20 on the client-side HP EFS WAN Accelerator effects passive FTP, while
	setting the QoS for port 20 on the server-side HP EFS WAN Accelerator effects active
	FTP.
	To configure optimization policies for the Messaging Application Protocol Interface
	(MAPI) data channel, define an in-path rule with the destination port 7830 and set its
	optimization policy.
