The two ports connected to 1 configure the MLT to access the two cores respectively. The SMLT does not need to generate a tree mechanism, and implements the loadbalance of Layer 2. The 8600 series can create 32 groups. The Single Port SMLT mode (server loadbalance) has no limit on the number of groups.
