You can create multiple links between devices that work as one virtual,
◆
aggregate link. A port trunk offers a dramatic increase in bandwidth for
network segments where bottlenecks exist, as well as providing a fault-
tolerant link between two switches.
When configuring static trunks, you may not be able to link switches of
◆
different types, depending on the manufacturer's implementation.
However, note that the static trunks on this switch are Cisco
EtherChannel compatible.
To avoid creating a loop in the network, be sure you add a static trunk
◆
via the configuration interface before connecting the ports, and also
disconnect the ports before removing a static trunk via the
configuration interface.
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, configure the trunk on the devices at both ends. 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.
You can create up to 14 trunks on a switch, with up to 16 ports per
■
trunk.
The ports at both ends of a connection must be configured as trunk
■
ports.
