When the -vci option is specified, the optrte command grooms only
those port connections that use the specified VCI. To display a list of
connections that includes the VPI and VCI for each connection, enter the
dspcons command.
When the -range option is specified, the optrte command grooms only
those port connections in the specified VPI and VCI range. Enter the
range using the format: starting-vpi/vci..ending-vpi/vci. You must enter
two periods between the starting VPI/VCI and the ending VPI/VCI. The
slash character is required between the VPI and VCI in each VPI/VCI
