5 Link aggregation
Link aggregation is used to converge multiple physical ports into a logical aggregation group.
Multiple physical links in one aggregation group are regarded as one logical link. The link
aggregation function binds multiple physical links into one logic link and enables them to share
traffic load for each other, thus increasing the bandwidth between the switch and the peer
device. Meanwhile, each member in an aggregation group backs up each other’s data
dynamically, improving connection reliability.
The network topology of link aggregation is as shown below.

Note
In the same aggregation group, all member ports must be set to the same configurations with respect to STP,
QoS, VLAN configuration and port management.
