Abstract: Embodiments include a system for implementing multipath selection of ethernet links in a fiber channel over ethernet (FCoE) network. A first VLAN defined a point-to-point path through the ethernet side of the network. A link failure in the first VLAN link is replaced by activating an alternate VLAN link corresponding to a new path through the ethernet side of the network while disabling all other VLANS corresponding to other paths through the ethernet side of the network. An advertisement is received from the origination SAN device on the fiber channel side of the network indicating a request for network access by the origination SAN device. Communications are enabled between the origination SAN device and the destination LAN device via the alternate VLAN link. Communications are then resumed between the origination SAN device and the destination LAN device utilizing the alternate VLAN link.
