Chapter 6 Managing Virtual Ports
58 Cajun M770 ATM Switch User’s Guide
Setting virtual port parameters
You can set individual parameters for a virtual port. Once a virtual port parameter
has been set, ILMI will not override the parameter when the virtual port is re-
enabled. If you want ILMI to override a set parameter, you must disable the virtual
port and clear the parameter. You must then re-enable the virtual port.
You can set the following virtual port parameters using the
vport set
command:
• Signalling profile
• Signalling stack type
• Signalling VPCI range
• Signalling VPCI base
• Signalling VCI range
• VPI range on a root virtual port
• ILMI version
• Waiting for incoming Q.SAAL connection.
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 parameter for a virtual port, you must perform the following steps:
1
Disable the virtual port.
2 Set the parameter for the disabled virtual port, as required.
3 Enable the virtual port.
Setting the signalling profile parameter
You can set the signalling profile on a virtual port to either “user” or “network”.
One side of the link must be set to “user” and the other side to “network”.
If ILMI is enabled, then normally end-stations are always the “user” side of a link.
For more information on which signalling profile should be used for an attached
device, see ATM port configuration in Chapter 2 Getting Started.
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.
