Abstract: Techniques are provided for performing discovery in a Fiber Channel over Ethernet (FCoE) network. An FCF discovers other FCoE Forwarders (FCFs) connected to its network segment by transmitting a solicitation message to the multicast MAC address “All-FCF-MACS”. All FCFs receive packets with this multicast MAC address including the solicitation message that announces the presence of the FCF. Each FCF replies with a unicast advertisement message that provides the new FCF with a MAC address of the responding FCF. The FCF builds a list of the FCFs available on its network segment and may then establish a virtual link with one or more of the FCFs through an exchange link parameter (ELP) exchange.

Abstract: An example method for Fibre Channel over Ethernet (FCoE) support in a Transparent Interconnection of Lots of Links (TRILL) network environment is provided and includes configuring at least two virtual storage area networks (SANs) in a TRILL network environment, which includes a plurality of leaf switches and spine switches, with each leaf switch being configured as a FCoE forwarder (FCF) enabled to forward frames according to FCoE protocol, and configuring at least an edge broadcast domain and a transport broadcast domain for each virtual SAN at each leaf switch. The edge broadcast domain includes end device links between the leaf switch and one or more end devices, and the transport broadcast domain includes spine links between the leaf switch and the spine switches.
