Support for converged traffic over ethernet link aggregation (LAG)

A method for providing link aggregation (LAG) to a converged network, the method comprising:

• receiving traffic on one or more ports of a plurality of ports, at least some ports being grouped together in a link aggregation (LAG);
• creating at least first virtual local area network (VLAN) interface for Ethernet traffic using transmission control protocol/internet protocol (TCP/IP) that is received on at least one of the plurality of ports, the first VLAN interface being used exclusively for traffic designated in a first VLAN;
• creating at least a second VLAN interface for at least one of storage area network (SAN) traffic using Fiber Channel over Ethernet (FCoE) and remote direct access memory (RDMA) over Converged Enhanced Ethernet (RoCEE) that is received on at least one of the plurality of ports, the second VLAN interface being used exclusively for traffic designated in a second VLAN;
• and
• maintaining an activity table, the activity table comprising information for each received packet, the information comprising at least:
• a VLAN for each received packet, at least one of a source media access control (MAC) address and a destination MAC address associated with each received packet, and one of an output port and an output LAG,
• wherein an output port is stored when the received packet was received on an individual port not associated with any LAG,
• wherein an output port is stored when the received packet was received on a port associated with a LAG and the received packet is designated as SAN traffic, and
• wherein an output LAG is designated when the received packet was received on a port associated with a LAG and the received packet is designated as Ethernet traffic,
• wherein no SAN traffic using the at least one of FCoE and RoCEE is assigned to the first VLAN interlace when forwarding SAN traffic, and
• wherein no Ethernet traffic using TCP/IP is assigned to the second VLAN interface when forwarding Ethernet traffic.

A computer program product for providing link aggregation (LAG) to a converged network, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code readable/executable by a computer to:

• receive network traffic on one or more ports of a plurality of ports, at least some ports being grouped together in a link aggregation (LAG);
• create at least a first virtual local area network (VLAN) interface for Ethernet traffic using transmission control protocol/internet protocol (TCP/IP) that is received on at least one of the plurality of ports, the first VLAN interface being used exclusively for traffic designated in a first VLAN;
• create at least a second VLAN interface for at least one of storage area network (SAN) traffic using Fiber Channel over Ethernet (FCoE) and remote direct access memory (RDMA) over Converged Enhanced Ethernet (RoCEE) that is received on at least one of the plurality of ports, the second VLAN interface being used exclusively for traffic designated in a second VLAN;
• maintain an activity table, the activity table comprising information for each received packet, the information comprising at least:
• a VLAN, a media access control (MAC) address, and at least one of an output port and a LAG designation;
• and
• choose an appropriate one of an output port and a LAG from the activity table when sending a packet,
• wherein no SAN traffic and only Ethernet traffic is forwarded using an output LAG via the first VLAN interface,
• wherein no SAN traffic using the at least one of FCoE and RoCEE is assigned to the first VLAN interface when forwarding SAN traffic, and
• wherein no Ethernet traffic using TCP/IP is assigned to the second VLAN interface when forwarding Ethernet traffic.
