Operation Manual – Link AggregationH3C S7500 Series Ethernet Switches Chapter 1 Link Aggregation Configuration1-121.4 Link Aggregation Configuration ExampleI. Network requirementsz Switch A connects to Switch B with three ports (Ethernet 2/0/1 through Ethernet2/0/3). It is required that incoming/outgoing load between the two switch can beshared among the three ports.z Adopt three different aggregation modes to implement link aggregation on thethree ports between switch A and B.II.

Configuration procedureThe following only lists the configuration on Switch A; you must perform the similarconfiguration on Switch B to implement link aggregation.z Adopt the manual aggregation mode# Create manual aggregation group 1. system-viewSystem View: return to User View with Ctrl+Z[H3C] link-aggregation group 1 mode manual# Add Ethernet 2/0/1 through Ethernet 2/0/3 to aggregation group 1.[H3C] interface ethernet2/0/1[H3C-Ethernet2/0/1] port link-aggregation group 1[H3C-Ethernet2/0/1] interface ethernet2/0/2[H3C-Ethernet2/0/2] port link-aggregation group 1[H3C-Ethernet2/0/2] interface ethernet2/0/3[H3C-Ethernet2/0/3] port link-aggregation group 1z Adopt the static LACP aggregation mode# Create static aggregation group 1.[H3C] link-aggregation group 1 mode static
