Parameter
lci: Logical channel identifier, its value ranges from 1 to 4095. If the logical channel
identifier is not specified, all virtual circuits will be displayed.
Description
Using the display x25 vc command, you can view the information about the X.25
virtual circuit.
SVC (Switched Virtual Circuit) is set up temporarily by X.25 through call
connection when data transmission is required. PVC is configured manually and
exists regardless of the data transmission requirement. When the router works in
X.25 switched mode, virtual circuits will be set up in order to transfer the switched
data. The information about these virtual circuits can be shown via this command,
and only some fields in the displayed information differ.
For the related commands, see x25 pvc, x25 switch pvc, x25 xot pvc, and x25 fr
pvc.
