Description
Use the
x25 vc-range
range.
Use the
undo x25 vc-range
By default, the upper and lower limits of two-way channel are 1 and 1024, of
incoming-only channel are both 0, and of outgoing-only channel are both 0.
By default, X.25 bans the incoming-only and outgoing-only channel sections and
reserves only the double direction channel section (in the range 1 to 1024). Please
configure the range correctly according to your ISP's requirement.
# Configure the incoming-only, two-way and outgoing-only channel ranges as [1,
7], [8, 1024] and [0, 0] respectively.

input-window-size: Size of input window. When X.25 window modulo is 8, its
value ranges from 1 to 7. When X.25 window modulo is 128, its value ranges
from 1 to 127.
output-window-size: Size of output window. When X.25 window modulo is 8, its
value ranges from 1 to 7. When X.25 window modulo is 128, its value ranges
from 1 to 127.

The default sizes are both 2.
The input-window-size determines the maximum number of correctly received
packets before X.25 sends the acknowledgement information. As long as the
bandwidth allows, the greater the window size, the higher the transmission
efficiency.
The parameter out-window-size determines the maximum number of data
packets sent by X.25 before it receives the correct acknowledgment information.
As long as the bandwidth allows, the greater the window size, the higher the
transmission efficiency.
