Abstract
A method and apparatus for multipath switching using per-hop virtual local area network (VLAN) remapping is disclosed. In the method and apparatus, a data packet is forwarded for transmission over one of a first port and a second port. The device identifies a VLAN ID of the data packet as a second VLAN ID and changes the second VLAN ID to a first VLAN ID. Then one or more criteria of a classification set entry for forwarding the data packet over the second port are evaluated. The data packet is forwarded over the second port if the criteria are met and the data packet is associated with the second VLAN ID. Alternatively, the data packet is forwarded over the first port and is associated with the first VLAN ID if a dynamic entry specifies the data packet is to be forwarded over the first port.
