Port Trunk Configuration
Ports can be combined into an aggregate link to increase the bandwidth of
a network connection where bottlenecks exist or to ensure fault recovery.
You can create up to six trunks at a time, with any single trunk containing
up to four ports.
a network connection where bottlenecks exist or to ensure fault recovery.
You can create up to six trunks at a time, with any single trunk containing
up to four ports.
The switch supports both static trunking and dynamic LACP (Link
Aggregation Control Protocol). LACP configured ports can automatically
negotiate a trunked link with LACP-configured ports on another device.
You can enable LACP on any port that is not already a member of a static
trunk. If LACP is also enabled for the connected ports on another device,
the switch and the other device will automatically create a trunked link.

You can enable LACP on any port that is not already a member of a static

the switch and the other device will automatically create a trunked link.
Besides balancing the load across each port in the trunk, the other ports
provide redundancy by taking over the load if a port in the trunk fails.
However, before making any physical connections between devices, use
the Web interface or CLI to specify the trunk on the devices at both ends.
When using a port trunk, take note of the following points:

When using a port trunk, take note of the following points:

Finish configuring port trunks before you connect the corresponding
network cables between switches to avoid creating a loop.
