Operation Manual – Link AggregationH3C S7500 Series Ethernet Switches Chapter 1 Link Aggregation Configuration1-8Caution:A load-sharing aggregation group contains at least two selected ports, however, anon-load-sharing aggregation group can have one selected port at most and others arestandby ports.1.2 Link Aggregation ConfigurationCaution:z The following ports cannot be added to an aggregation group: destination ports tobe mirrored to, reflection ports of remote mirroring, ports configured with static MACaddresses, static-ARP-enabled ports, and 802.1x-enabled ports.z Ports where the IP-MAC address binding is configured cannot be added to anaggregation group.Note that:1) When creating an aggregation group:z If the aggregation group you are creating already exists but contains no port, itstype will change to the type you set.z If the aggregation group you are creating already exists and contains ports, thepossible type changes may be: changing from dynamic or static to manual, andchanging from dynamic to static; and no other kinds of type change can occur.z When you change a dynamic/static group to a manual group, the system willautomatically disable LACP on the member ports. When you change a dynamicgroup to a static group, the system will remain the member ports LACP-enabled.2) When a manual or static aggregation group contains only one port, you cannotremove the port unless you remove the whole aggregation group.1.2.1 Configuring a Manual Aggregation GroupYou can create a manual aggregation group through the following operations. And youcan remove an existing manual aggregation group. After that, all the ports in the groupare removed from the group).A port can only be manually added/removed to/from a manual aggregation group.Follow these steps to configure a manual aggregation group:
