L2 algorithm—Layer 2 source and destination MAC addresses. Available on BlackDiamond 8800 series switches, SummitStack, and all Summit family switches.
L3 algorithm—Layer 3 source and destination IP addresses. Available on BlackDiamond 8800 series switches, Summit family switches, and SummitStack.
L3_L4 algorithm—Layer 3 and Layer 4, the combined source and destination IP addresses and source and destination TCP and UDP port numbers. Available on Summit family switches, BlackDiamond 8000 a-, c-, and e-series modules.
IPv4 and IPv6 packets—When BlackDiamond 8900 series modules are installed in a BlackDiamond 8800 series switch, load sharing on all other module or switch types is based on the combined source and destination IP addresses and source and destination TCP and UDP port numbers.
Non-IP traffic—The source and destination MAC addresses.
Note
On platforms such as Summit X670, X670v, X480, X460, and Black Diamond 8900 series I/O modules, load sharing based on inner L3 fields in the MPLS terminated packet are not supported and the packets will be forwarded as per L2 hashing.You can control the field examined by the switch for address-based load sharing when the load-sharing group is created by using the following command:
enable sharing port grouping port_list {algorithm [address-based {L2 | L3 | L3_L4 | custom} | port-based }]} {lacp | health-check}
