• Source/Destination IP and source/destination TCP/UDP Port fields of the packet. Enhanced LAG Hashing Dell Networking devices based on Broadcom XGS-IV silicon support configuration of hashing algorithms for each LAG interface. The hashing algorithm is used to distribute traffic load among the physical ports of the LAG while preserving the per-flow packet order. NOTE: Enhanced hashing mode is not supported on the N1108EPON/N1500 Series switches. One limitation with earlier LAG hashing techniques is that the packet attributes were fixed for all type of packets. Also, there was no MODULO-N operation involved, which can result in poor load balancing performance. The LAG hashing support supports an enhanced hashing mode, which has the following advantages: • MODULO-N operation based on the number of ports in the LAG. • Packet attributes selection based on the packet type. For L2 packets, Source and Destination MAC address are used for hash computation. For IP packets, Source IP, Destination IP address, TCP/UDP ports are used. • Non-Unicast traffic and Unicast traffic is hashed using a common hash algorithm. • Excellent load balancing performance. • Enhanced LAG hashing is the default hashing mode for LAGs on switches that support it. Manual Aggregation of LAGs Dell Networking switching supports the manual addition and deletion of links to aggregates. In the manual configuration of aggregates, the ports send their Actor Information (LACPDUs) to the partner system in order to find a suitable Partner to form an aggregation. When the Partner System neglects to respond using LACPDUs, the Dell Networking switching aggregates manually. The Dell Networking switching uses the currently configured default Partner Values for Partner Information. Layer 2 Switching Commands 701
