Page 2: Chapter 1 Link Aggregation Configuration
Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration Chapter 1 Link Aggregation Configuration 1.1 Overview 1.1.1 Introduction to Link Aggregation Link aggregation means aggregating several ports together to form an aggregation group, so as to implement outgoing/incoming load sharing among the member ports in the group and to enhance the connection reliability. -
Page 3: Operation Key
Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration 1.1.3 Operation Key An operation key of an aggregation port is a configuration combination generated by system depending on the configurations of the port (rate, duplex mode, other basic configuration, and management key) when the port is aggregated. -
Page 4: Static Lacp Aggregation Group
Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration The system sets the ports unable to aggregate with the master port (due to some hardware limit, for example, cross-board aggregation unavailability) to unselected state. The system sets the ports with port attribute configuration (rate, duplex mode, and link type) different from that of the master port to unselected state. -

Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration II. Port status of static aggregation group A port in a static aggregation group can be in one of the two states: selected or unselected. In a static aggregation group, both the selected and the unselected ports can transceive LACP protocol packets;... - Page 6 Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration Besides multiple-port aggregation groups, the system is also able to create single-port aggregation groups, each of which contains only one port. LACP is enabled on the member ports of dynamic aggregation groups.

Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration Note: Changing the system priority of a device may change the preferred device between the two parties, and may further change the states (selected or unselected) of the member ports of dynamic aggregation groups. - Page 8 Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration An aggregation group containing special ports (such as 10GE port) which require hardware aggregation resources has higher priority than any aggregation group containing no special port.

Operation Manual – Link Aggregation H3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration 1.2 Link Aggregation Configuration Caution: The commands of link aggregation cannot be configured with the commands of port loopback detection feature at the same time. The ports where the mac-address max-mac-count command is configured cannot be added to an aggregation group. -
