One embodiment of the present invention provides a switch capable of auto-configuration of client devices for a link aggregation. The switch includes a packet processor, an auto-configuration module, and a link-aggregation management module. During operation, the packet processor extracts an identifier of a client device from a notification message received via a local port. The auto-configuration module, which is coupled to the packet processor, associates the local port with the identifier of the client device. If the packet processor recognizes the identifier of the client device in a message received from a remote switch, the link-aggregation management module forms a multi-switch link aggregation for the client device in conjunction with the remote switch.

Techniques implementing redundancy in an extended bridge comprising a controller bridge (CB) unit and a plurality of port extender (PE) units are provided. In one embodiment, the CB unit can receive join requests from the plurality of PE units and can determine, based on the join requests, whether the plurality of PE units are physically connected to the CB unit and/or other CB units in the extended bridge according to a ring topology. If the plurality of PE units are physically connected to the CB unit or the other CB units according to a ring topology, the CB unit can select a link in the ring topology as being a standby link.

Techniques for virtualizing hardware hash tables in a networking system are provided. In one embodiment, the networking system can maintain a plurality of virtual hash tables corresponding to a plurality of hardware hash tables in the networking system. For each hardware hash table and its corresponding virtual hash table, the networking system can intercept operations directed to the hardware hash table and apply the intercepted operations to the virtual hash table. The networking system can then selectively install and/or uninstall virtual hash table entries to/from the hardware hash table in view of the operations.
