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 configure trunks between any two switches of the same type. You
can create up to six trunks at a time. The uplink ports can be trunked
together and the VDSL ports can be trunked together, the details
are given
in the table below.
The switch supports both static trunking and dynamic LACP (Link
Aggregation Control Protocol.) LACP configured ports will automatically
negotiate a trunked link with LACP-configured ports on another device.
You can configure any number of the ports on the switch as LACP, as long
as they are not already configured as part of another trunk. If ports on
another device are also configured as LACP, the switch and the other
device will negotiate a trunk link between them. If an LACP trunk consists
of more than four ports, all other ports will be placed in a standby mode.
Should one link in the trunk fail, one of the standby ports will
automatically be activated to replace it.
Command Usage
• Finish configuring a port trunk before you connect the corresponding
network cables between switches.
• You can configure one trunk group, containing up to four ports as a
dynamic LACP trunk.
