OMMANDS
Parameters
Example
minna (config) # protocol connection lan receive buf-size 1000000
minna (config) #
protocol connection lan send buf-size
Description Sets the LAN send buffer size for HSTCP support.
The no command option resets the buffer size to the default.
You must increase your LAN buffer size to 1 MB. For detailed information about
configuring HSTCP, see “tcp highspeed enable” on page 193.
Syntax [no] protocol connection lan send buf-size <bytes>
Parameters
Example
minna (config) # protocol connection lan receive buf-size 1000000
minna (config) #
protocol connection wan receive def-buf-size
Description Sets the WAN default-receive buffer size for HSTCP support.
The no command option resets the buffer size to the default.
For detailed information about configuring HSTCP, see “tcp highspeed enable” on
page 193.
Syntax [no] protocol connection wan receive def-buf-size <bytes>
Parameters
Usage To configure your WAN buffer 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 receive def-buf-size 3875000
minna (config) #
<bytes> Specifies the LAN default receive buffer size. The default value is 32768.
<bytes> Specifies the WAN default-send buffer size. The default value is 81920.
<bytes> Specifies the WAN default-receive buffer size. The default value is
262140.
