HP StorageWorks Enterprise File Services WAN Accelerator 2.1.7 Command-Line Interface Reference Manual (392361-004, June 2006)

134 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 enable
Description Messaging Application Programming Interface (MAPI) optimization is enabled by
default. The no protocol mapi enable command disables MAPI optimization for
testing purposes.
If you are experiencing problems with Outlook clients connecting with Exchange, you
can disable MAPI latency acceleration (while continuing to optimize with SDR for
MAPI) by issuing the no protocol mapi enable command.
Syntax protocol mapi enable
Parameters None
Example
minna (config) # no protocol mapi enable
minna (config) #
protocol mapi 2k3 enable
Description Enables Exchange 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
<bytes> Specifies the WAN default-send buffer size. The default value is 262140.
