Abstract
One embodiment of the present invention provides a switch. The switch includes a link aggregation database, an arbitration module, a packet processor, and a logical connection management module. The link aggregation database stores information regarding a plurality of switches participating in a multi-chassis trunk. The plurality of switches includes the switch as well. The arbitration module selects a switch of the plurality of switches as an active switch based on the information in the link aggregation database. The packet processor constructs a packet for a remote switch forwardable via a logical connection. The logical connection management module operates in conjunction with the packet processor and constructs a message containing instructions for creating a second logical connection to a second switch of the plurality of switches.
