Abstract
Systems and methods for managing a large number of multi-stage switches in a data center are provided. In one aspect, a plurality of first stage switches in a switch cluster may be configured to function as a proxy switch for a given number of second stage switches in the switch cluster. Each of the first stage switches may thus receive, via a first set of networking links, inbound control plane management traffic destined for respective ones of the given number of second stage switches. The first stage switches may then route the control plane management traffic to the appropriate second stage switches via a second set of bidirectional links. In addition, each of the second stage switches may be further configured to route outbound data traffic originating from the second stage switches using all available uplinks in the second set of bidirectional links.
