1. A node in a communications network, comprising:
- an identification code;
a control mechanism including configuration information for the node; and
an alarm generator in the control mechanism for raising an alarm to a network user if there is a mismatch between the identification code and the configuration information.

Abstract
A system and method for protecting and recovering configuration information in a node during a configuration mismatch. The configuration mismatch may involve the insertion of a foreign switch management card into a node chassis. The configuration mismatch may alternatively involve a discrepancy between a hardware configuration of the node and the software configuration of the node. A mismatched node notifies a user of the mismatch and prevents mismatched configuration information from being downloaded to the node. The node utilizes default configuration information to maintain a traffic flow during mismatch while the node undergoes recovery procedures.

15. A method for restoring configuration information in a node of a communications network, comprising:
-
performing a consistency check between an identification code programmed into the node and configuration information stored in a control mechanism in the node; and
raising an alarm if the consistency check reveals a mismatch between the identification code and the configuration information.

19. A method of preserving configuration information in a node of a communications network when there is a discrepancy between a hardware configuration and configuration information stored in a control mechanism for the node, comprising:
-
performing a consistency check between the configuration information stored in the control mechanism and the hardware configuration of the node and in the vicinity of the node; and
raising an alarm if said consistency check fails to validate said configuration information against the hardware configuration.
