The S7900E Series Ethernet Switches are distributed devices supporting Intelligent Resilient
Framework (IRF). Two S7900E series can be stacked together to form a distributed stacking device. If
an S7900E series is not in any IRF, it operates as a distributed device; if the S7900E series is in an IRF,
it operates as a distributed stacking device. For introduction of IRF, refer to IRF in the System Volume.
Overview
Link aggregation aggregates multiple physical Ethernet ports to increase the link speed beyond the
limits of any one single port. The Ethernet ports bundled together form an aggregation group. To upper
layer entities such as applications running on the network, they look like a single logical link and thus
can operate without modification.
Link aggregation allows you to increase bandwidth by distributing traffic across the member ports in an
aggregation group. Because these member ports can dynamically back up each other, it improves
connectivity reliability in addition.
Basic Concepts of Link Aggregation
Aggregate interface
An aggregate interface is a logical Layer 2 or Layer 3 aggregate interface manually created for link
aggregation.
Current device only supports Layer 2 aggregate interface.
