window-size and packet-size options are also supported in
x25 pvc
command.
However, in
x25 pvc
command, these two options specify the window size and
maximum packet length of the set PVC. If these two options are not selected in
the
x25 pvc
command, the set PVC will choose the default value of X.25
interface.
name is the name of the ROA ID list configured by the command x25 roa-list in
the system view, for example:
[Router]x25 roa-list list1 12 34 567
In the serial port view, list1 can be quoted:
[Router-Serial0]x25 call-facility roa-name list1
5 Configure the sending queue length of virtual circuit
The sending and receiving queue lengths of the virtual circuit can be specified for
the X.25 of the 3Com Router series to adapt to different network environments.
The default queue length can contain 500 packets, but if data flow is very large, or
the transmission rate of the X.25 network is low, the queue length can be
increased to avoid unexpected data packet loss.
In the interface view, perform the following tasks to specify the length of virtual
circuit queue.
