Link aggregation of ports on different units in the stack.

Not all stackable switches support link aggregation across the stack.

Beside increasing bandwidth another reason for link aggregation is redundancy.

Ethernet links use link aggregation as a mechanism to recover from failures.

Some switches do not implement the 802.1AX standard but support static configuration of link aggregation.

Link aggregation addresses two problems with Ethernet connections: bandwidth limitations and lack of resilience.

Multilink PPP is an example of a link aggregation technology.

This is called link aggregation.

With Static link aggregation a cabling or configuration mistake could go undetected and cause undesirable network behavior.

Link aggregation can allow the use of these extra cables to increase backbone speeds for little or no extra cost if ports are available.

With static link aggregation the peer would continue sending traffic down the link causing the connection to fail.

Microsoft Windows does support native link aggregation starting from Windows Server 2012.

This became known as "Link Aggregation Control Protocol".

Dynamic configuration: The device can confirm that the configuration at the other end can handle link aggregation.

Note the data signaling rate will still be 1Gbit/s, which can be misleading depending on methodologies used to test throughput after link aggregation is employed.

The listener must use channel bonding or link aggregation to merge the two connections into one aggregate interface to see both halves of the traffic.

EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches.

Stackable up to 8-units high using Gigabit ports with distributed link aggregation, single IP address management.

Link aggregation also allows the network's backbone speed to grow incrementally as demand on the network increases, without having to replace everything and buy new hardware.

Trees can support link aggregation (LAG) groups within a tree "branch" segment where some form of hashing occurs.

A general limitation of standard MLT is that all the physical ports in the link aggregation group must reside on the same switch.

Link aggregation offers an inexpensive way to set up a high-speed backbone network that transfers much more data than any one single port or device can deliver.

The uplink will typically be a port (or link aggregation group) connected to a router, firewall, server, provider network, or similar central resource.

The switch also has 2 SFP uplink ports for link aggregation or as uplinks to aggregation switches.

A major complication of existing link aggregation or bonding technologies is that all members interfaces of such a team/group need to terminate on one single logical switch.
