Preconfiguring Physical Interfaces
This module describes the preconfiguration of physical interfaces.
Preconfiguration is supported for these types of interfaces and controllers:
• 10-Gigabit Ethernet
• Management Ethernet
• Serial
• SONET controllers and channelized SONET controllers
Preconfiguration allows you to configure modular services 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 [RP]), rather than with the regularly configured interfaces.
There may be some preconfiguration data that cannot be verified unless the modular services card is present,
because the verifiers themselves run only on the modular services card. Such preconfiguration data is verified
when the modular services 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.
Only physical interfaces can be preconfigured.
