Showing Virtual Port Information
Listing information about virtual ports
You can view information about all of the virtual ports on the M770 ATM Switch.
When a module is installed in the M770 ATM Switch, default virtual ports are
created for the ports. Each of these default virtual ports is assigned a virtual port id
of zero.
Any virtual port information that is marked with an asterisk (*) has been learned by
the M770 ATM Switch during the ILMI dialogue with the remote device.
Information that is not marked with an asterisk has been either configured by the
user or is the default setting for the virtual port.
To view configuration information about all of the virtual ports, use the vport
show command with the following parameters.
Command:
M15-155s8:/>vport show [config | status | vpivciranges]
Parameter:
When no
