Chapter 3 CLI Commands
(config) tcp
(config) tcp
To configure TCP parameters on a WAAS device, use the tcp global configuration command. To disable
TCP parameters, use the no form of this command.
tcp {cwnd-base segments | ecn enable | increase-xmit-timer-value value |
init-ss-threshold value | keepalive-probe-cnt count | keepalive-probe-interval seconds |
keepalive-timeout seconds}
no tcp {cwnd-base segments | ecn enable | increase-xmit-timer-value value |
init-ss-threshold value | keepalive-probe-cnt count | keepalive-probe-interval seconds |
keepalive-timeout seconds}
Syntax Description
Defaults tcp cwnd-base: 2
tcp increase-xmit-timer-value: 1
tcp init-ss-threshold: 2 segments
tcp keepalive-probe-cnt: 4
tcp keepalive-probe-interval: 75 seconds
tcp keepalive-timeout: 90 seconds
Command Modes global configuration
Device Modes application-accelerator
central-manager
cwnd-base segments Sets initial send congestion window in segments (1–10).
ecn enable Enables TCP explicit congestion notification.
increase-xmit-timer-value
value
Specifies the factor (1-3) used to modify the length of the retransmit
timer by 1 to 3 times the base value determined by the TCP algorithm.
Note Use this keyword with caution. The keyword can improve
throughput when TCP is used over slow reliable connections but
should never be changed in an unreliable packet delivery
environment.
init-ss-threshold value Sets initial slow-start threshold value (2-10).
keepalive-probe-cnt count Specifies the length of time that the WAAS device keeps an idle
connection open. The number of probe counts is 1–10.
keepalive-probe-interval
seconds
Specifies the number of times that the WAAS device retries a
connection. The keepalive probe interval is in seconds (1–300).
keepalive-timeout seconds Specifies the length of time that the WAAS device keeps a connection
open before disconnecting. The keepalive timeout is in seconds
(1–3600).
