Chapter 6 Managing Virtual Ports
Avaya M770 ATM Switch User’s Guide 73
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 on page 98.
Note: You must disable the virtual port before you can change or reset any virtual
port parameters. For more information about how to disable a virtual port, see
“Disabling a virtual port” on page 65.
To set a signalling VCI range for a virtual port, use the vport set vcirange
command.
Note: Do not reduce the lower limit of the signalling VCI range below 32. All values
below 32 are reserved for signalling protocol.
Setting the VPI range on a root virtual port
The VPI range set for the root virtual port cannot be greater than the VPI range of
the physical port.
Note: Before you can create a new virtual port you must reduce the VPI range of the
root virtual port. For more information about creating a virtual port, see “Creating a
virtual port” on page 64.
To set a VPI range for a root virtual port, use the
vport set vpirange command.
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.
Command:
M15-155s8:/>vport set vpirange <vport id> <range>
Example:
M15-155s8:/>vport set vpirange 8.1.0 [0..3]
Parameters:
<vport id>
The virtual port in the form
<slot>.<port>.<virtual port number>.
<range>
Selects the VPI range that will be used for the
virtual port. The upper range can be 0, 1, 3 or 7.
