Preconfiguring Physical Interfaces
This module describes the preconfiguration of physical interfaces.
Preconfiguration is supported for these types of interfaces and controllers:
• 100-Gigabit Ethernet
• Management Ethernet
Preconfiguration allows you to configure line cards before they are inserted into the router. When the cards
are inserted, they are instantly configured. The preconfiguration information is created in a different system
database tree (known as the preconfiguration directory on the route processor), rather than with the regularly
configured interfaces.
There may be some preconfiguration data that cannot be verified unless the line card is present, because the
verifiers themselves run only on the line card. Such preconfiguration data is verified when the line card is
inserted and the verifiers are initiated. A configuration is rejected if errors are found when the configuration
is copied from the preconfiguration area to the active area.
One Gigabit Ethernet interface is not supported. Only physical interfaces can be preconfigured.

Physical Interface Preconfiguration Overview
Preconfiguration is the process of configuring interfaces before they are present in the system. Preconfigured
interfaces are not verified or applied until the actual interface with the matching location (rack/slot/module)
is inserted into the router. When the anticipated line card is inserted and the interfaces are created, the precreated
