The following table describes the commands used for performing common actions related to acceleration tcp:

Action Description

Command

Parameter Description

To set the WAN (Wide Area Network) side congestion control algorithm

acceleration tcp cc {cubic|hybla|highspeed| veno|reno|bic|vegas|htcp|yeah |illinois|scalable|lp|westwood}

Not Applicable

To enable appliance auto-discovery

[no] acceleration tcp discovery

Not Applicable

To enable accelerated traffic to be processed on only one bridge

[no] acceleration tcp dual-bridge-bypass

When enabled, acceleration will be processed on only one bridge, which is good for backhauled settings. Default is enabled.
When disabled, accelerated traffic can be handled on any bridge, which is good for aggregated link settings with asymmetric routes.

To manage keep-alive settings

[no] acceleration tcp keep-alive {enable|timeout}

enable - Enables the sending of keep-alive packets on the WAN. The timeout specifies when to activate the keep-alive packets if enabled.
timeout - Specifies the amount of time, in seconds, that a connection may be idle before sending keep-alive packets is enabled. Keep-alive packets are sent once per minute until either a response is received, or 5 minutes pass. If five minutes pass without a response the connection is terminated.

To set the transport mode

acceleration tcp transport {transparent|tunnelled}

Not Applicable

To set the window scaling factor, which determines how large the TCP window is allowed to grow per connection

acceleration tcp window-scale <factor>

<factor> - 0 - 14. The default is 5, which equates to a TCP window of 2MB. Increasing one step in the factor doubles the TCP window size.
