UIDELINES
◆ 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.
