Preconfiguring Physical Interfaces
This module describes the preconfiguration of physical interfaces on the .
Preconfiguration is supported for the following types of interfaces and controllers:
-
ATM
-
Gigabit Ethernet
-
10-Gigabit Ethernet
-
Management Ethernet
-
Packet-over-SONET/SDH (POS)
-
Spatial Reuse Protocol (SRP)
-
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. |
