This topic summarizes restrictions for physical interface preconfiguration that affect planning, validation, and execution.
These restrictions apply for physical interface preconfiguration:
-
You must provide names during preconfiguration that matches with the name of the interface that is created. If the interface names do not match, the system does not apply preconfiguration when the interface is created.
-
The interface names must begin with the interface type that is supported by the router and for which drivers have been installed. However, the slot, port, subinterface number, and channel interface number information cannot be validated.
-
It is possible that you are not able to verify some configurations until you insert the line card is inserted.
-
Specifying an interface name that already exists and is configured , or an abbreviated name like Hu0/3/0/0 is not permitted.
-
Do not enter the no shutdown command for new preconfigured interfaces, because the no form of this command removes the existing configuration, and there is no existing configuration.
Gigabit Ethernet interface is not supported. You can only preconfigure physical interfaces.
