Abstract
Techniques are described for supporting Fiber Channel over Ethernet (FCoE) link aggregation groups (LAGs) between a server and a data center switch in a data center. The techniques enable an access switch in the data center switch to assign class identifiers to each member link in an FCoE LAG between an FCoE node (Enode) of the server and the access switch. In this way, the access switch is able to redirect FCoE traffic from a Fiber Channel forwarder (FCF) of a storage area network (SAN) toward the Enode on the correct member link of the FCoE LAG. The techniques also enable scaling of FCoE initialization protocol (FIP) and FCoE sessions by installing FIP snooping filters that use on a source media access control (MAC) address hit determination in ingress filter processors (IFPs) of the access switch to avoid session limitations of virtual local area network (VLAN) filter processors (VFPs).
