Chapter 6 Managing Virtual Ports
Avaya M770 ATM Switch User’s Guide 71
Setting the signalling VPCI range
You can set a signalling VPCI range for a virtual port. This range can only be
changed on the root virtual port.
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 VPCI range for a virtual port, use the vport set
sigvpcirange command.
Setting the signalling VPCI base
You can set a signalling VPCI Base for a non-root virtual port. This command
enables the switch to interoperate with switches that use the VPI value for the VPCI
in the setup signalling message. The default VPCI value is ‘0’.
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 VPCI base for a virtual port, use the vport set sigvpcibase
command.
Command: M15-155s8:/>vport set sigvpcirange <vport id> <range>
Example: M15-155s8:/>vport set sigvpcirange 8.1.0 [0..2]
Parameters: <vport id> The virtual port in the form <slot>.<port>.<virtualport number>.
<range> Selects the signalling VPCI range that will be used for the virtual
port.
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.
