snooping and study state. The time ranges from 4 seconds to 30
seconds.

4.5 Configuring Link Aggregation
Link aggregation is to form a multiple physical ports of the switch into the logical port. The multiple
links in the same group can be regarded as a logical link with a larger bandwidth.
Through aggregation, the ports in the same group can share the communication flow, to make a
larger bandwidth. Besides, the ports in the same group can back up reciprocally and dynamically to
enhance the link reliability.
●
The link aggregation is mutually exclusive with STP mode, IGMP Snooping, and 802.1x mode.
When STP mode is enabled, link aggregation cannot be configured. You must disable STP mode
before configuring link aggregation.
●
We do not recommend implementing configuration and advanced functions for the ports which
are used for link aggregation.
●
Link aggregation can be divided into static aggregation and LACP. Generally, the peer devices
with the switch link aggregation are switch and network adapter.
