Chapter 6 Managing Virtual Ports
Cajun M770 ATM Switch User’s Guide 61
To set a signalling VPCI base for a virtual port, use the
vport set sigvpcibase
command.
Setting the signalling VCI range
You can set the signalling VCI range used for SVCs on a virtual port. Usually the VCI
range is reduced in order to create PVCs on these VCs. To increase the VPI range or
vice versa, please see the command
hardware vpivcibits
in Chapter 7
Managing Module Hardware.
Note:
Before any virtual port parameters can be changed or reset, you must disable
the virtual port. For more information about how to disable a virtual port, see
Disabling a virtual port earlier in this chapter.
To set a signalling VCI range for a virtual port, use the
vport set vcirange
command.
Command:
M15-155s8:/>vport set sigvpcibase <vport id> 0|vpi
Example:
M15-155s8:/>vport set sigvpcibase 8.1.2 vpi
Parameters:
<vport id>
The virtual port in the form
<slot>.<port>.<virtual port number>
<0|vpi>
Selects the signalling VPCI base that will be
used for the virtual port. To interoperate
with another M770 ATM Switch, set it to
‘0’.
This is the default setting.
Command:
M15-155s8:/>vport set vcirange <vport id> <range>
Example:
M15-155s8:/>vport set vcirange 8.1.0 [32..800]
Parameters:
<vport id>
The virtual port in the form
<slot>.<port>.<virtual port number>.
<range>
Selects the signalling VCI range that will be
used for the virtual port. The range must be
in the form [x..y] where x > 32 and
y < maximum vci as defined by the number
of VCI bits.
