window size on the X.25 interface. Using the undo x25 window-size command, you
can restore to the default value.
Default incoming window size on the X.25 interface is 2 packets.
in-packets specifies the maximum count of correct packets received before X.25 sends
correct acknowledgement. As long as the bandwidth allows, the greater the window
size is, the higher the transmission efficiency.
out-packet specifies the maximum count of correct packets received before X.25 sends
correct acknowledgements. As long as the bandwidth allows, the greater the window
size is, the higher the transmission efficiency.
Please consult your ISP about the incoming and outgoing window size. Unless
supported by the network, do not set these two parameters to different values.
