Chapter 6 Managing Virtual Ports
64 Cajun M770 ATM Switch User’s Guide
Resetting virtual port parameters
You can reset a virtual port parameter so that the value returns to the default value.
When the virtual port is re-enabled ILMI will, where possible, attempt to learn a
value for the parameter through its dialogue with the remote device. If ILMI cannot
discover a value for the parameter, the parameter remains at the default setting.
You can reset the following virtual port parameters using the
vport reset
command:
• Signalling profile
• Stack type
• Signalling VPCI range
• Signalling VPCI base
• Signalling VCI range
• VPI range on a root virtual port.
• ILMI version
• Waitqsaal.
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 clear a parameter for a virtual port, you must perform the following steps:
1
Disable the virtual port.
2 Reset the parameter for the disabled virtual port.
3 Enable the virtual port.
Resetting the signalling profile parameter
If you reset the virtual port’s signalling profile parameter, the port will re-learn
what is on the other end of the link when it is enabled and a remote device is
connected. For more information about this parameter, see Setting the signalling
profile parameter earlier in this chapter.
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.
