CLI – The following example enables LACP for ports 17 and 18. Just connect these
ports to two LACP-enabled trunk ports on another switch to form a trunk.
Statically Configuring a Trunk
Command Usage
• 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.
