Table 2-11 Proxy-policy TCP Configuration Submode Command Descriptions (continued)

[no] buffer-share rx buffer-limit-in-bytes	Allows you to configure the maximum size of the receive buffer share per
	connection; valid values are from 8192 to 262144. Use the no form of this
	command to return to the default setting.
[no] buffer-share tx buffer-limit-in-bytes	Allows you to configure the maximum size of the transmit buffer share per
	connection; valid values are from 8192 to 262144. Use the no form of this
	command to return to the default setting.
delayed-ack-threshold	Allows you to specify the number of full-sized segments that must be
	received before a window-update ACK is sent. Valid values for packets are
	1 to 10; the default value is 2.
delay-ack-timeout	Allows you to specify the amount of time before a window-update ACK is
	sent.
	If the number of full-sized segments (as specified in the
	delayed-ack-thresholdcommand) is not received before this timer expires,
	then an ACK is sent acknowledging all data received up to this point, but
	the window is not updated. Valid values for timer are 50 to 500
	milliseconds; the default value is 200.
help	Provides a description of the interactive help system.
[no] mss max-segment-size-in-bytes	Allows you to configure the maximum segment size that the connection
	identifies in the generated SYN packet; valid values are from 64 to 1460.
	Use the no form of this command to return to the default setting.
[no] nagle	Allows you to enable the the Nagle algorithm.
	When you enable the nagle keyword, small amounts of data that are written
	by the application is queued into the connection-send queue, but is not sent
	until one of the following situations occurs:
	• There is data pending and an ACK arrives that acknowledges the data
	that was previously sent.
	• The application writes more data so that a full-sized segment is created
	and sent.
	When you disable the nagle keyword, queueing of data does not occur. All
	data that is written by the application is sent immediately.
	Nagle is enabled by default.
[no] timeout fin-wait timeout-in-seconds	Allows you to configure the FIN wait timeout; valid values are from 75 to
	600 seconds. Use the no form of this command to return to the default
	setting.
[no] timeout inactivity timeout-in-seconds	Allows you to configure the inactivity timeout; valid values are from 0 to
	960 seconds. This command allows you to set the aging timeout for an idle
	connection and helps protect the connection resources. Use the no form of
	this command to return to the default setting.
[no] timeout syn timeout-in-seconds	Allows you to configure the connection establishment timeout; valid values
	are from 5 to 75 seconds. Use the no form of this command to return to the
	default setting.
