MANAGEMENT OF A DISTRIBUTED FABRIC SYSTEM
First Claim
1. A method for managing a distributed fabric system in which a plurality of scaled-out fabric coupler (SFC) chassis is connected to a plurality of distributed line card (DLC) chassis over fabric communication links, the method comprising:
- detecting, by a fabric element chip of each SFC chassis, connectivity between the fabric element chip of that SFC chassis and a fabric interface of a switching chip of one or more of the DLC chassis;
storing in memory, in response to the detected connectivity, connection information for each fabric communication link between the fabric element chip of that SFC and a fabric interface of a switching chip of the one or more of the DLC chassis;
accessing the memory to acquire the connection information for each fabric communication link; and
constructing a topology of the distributed fabric system from the acquired connection information for each communication link.

Abstract
A distributed fabric system has distributed line card (DLC) chassis and scaled-out fabric coupler (SFC) chassis. Each DLC includes a network processor and fabric ports. Each network processor includes a fabric interface in communication with the fabric ports of that DLC. Each SFC includes at least one fabric element and SFC fabric ports. A fabric communication link connects each SFC fabric port to one DLC fabric port. Each fabric communication link includes cell-carrying lanes. Each fabric element detects connectivity between each SFC fabric port of that SFC and one DLC fabric port over a fabric communication link. Each SFC reads a connectivity matrix from fabric element chips and sends connection information corresponding to the detected connectivity from that SFC to a central agent. A network element includes the central agent, which, when executed, constructs a topology of the distributed fabric system from the connection information sent from each SFC.
