Name
ip tcp window-size — global
Synopsis
ip tcp window-sizebytesno ip tcp window-sizebytes
Configures
The window size of a TCP connection
Default
2144 bytes
Description
This command sets the size of the TCP window to
bytes. Changing the size of the TCP window
modifies the size and number of packets that can fit within that
window. With the default window of 2144 bytes, you could buffer two
1000-byte packets, or 21 100-byte packets. Regardless of the
window’s size, the number of packets within the window is
restricted to the values set by the ip
tcp
queuemax command; they
default to 5 for TTY interfaces (async and console interfaces) and 20
for other interfaces. The maximum size of the window is 65536
bytes.
Example
ip tcp window-size 4000
