HP StorageWorks Enterprise File Services WAN Accelerator 2.1.5 Command-Line Interface reference manual (June 2006)

130 4 - CONFIGURATION-MODE COMMANDS
Syntax protocol connection wan send def-buf-size <bytes>
Parameters
Usage To configure your WAN buffer size you must:
 increase the WAN buffers to 2 Bandwidth Delay Product (BDP) or 10 MB. You
can calculate the BDP WAN buffer size. For a link of 155 Mbps and 100 ms
round-trip delay, the WAN buffers should be set to:
2 * 155 Mbps * 100 ms = 1937500 bytes
Example
minna (config) # protocol connection wan send def-buf-size 3875000
minna (config) #
protocol mapi 2k3 enable
Description Enables Exchange Messaging Application Programming Interface (MAPI) 2003
acceleration which allows increased optimization of traffic between Exchange 2003
and Outlook 2003. The no command option disables MAPI 2003 support.
Syntax protocol mapi 2k3 enable
Parameters None
Example
minna (config) # protocol mapi 2k3 enable
minna (config) #
protocol mapi nspi
Description Sets the Name Service Provider Interface (NSPI) port. In certain situations (for
example, clients connecting through a firewall), you might want to force a server to
listen on a single pre-defined port so that access to ports can be controlled or locked
down on the firewall. The no command option disables NSPI support.
In out-of-path deployments, if you want to optimize MAPI Exchange by destination
port. You must define in-path rules that specify the following ports on the client-side
HP EFS WAN Accelerator:
 Port 135. The Microsoft end-point mapper port
 Port 7830. The HP EFS WAN Accelerator port used for Exchange traffic
 Port 7840. The HP EFS WAN Accelerator port used for Exchange Directory
NSPI traffic
If you changed the Microsoft Exchange Information Store Interface port in your
environment, in the Setup: Advanced Networking - Protocol MAPI page on the client-
side HP EFS WAN Accelerator, change port 7830 to the static port number you have
configured in your Exchange environment. The CLI commands for MAPI and NSPI
port configuration are:
<bytes> Specifies the WAN default-send buffer size. The default value is 262140.
