standby mode. Should one link in the trunk fail, one of the standby ports will automatically
be activated to replace it.
Command Usage
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:
• Finish configuring port trunks before you connect the corresponding network cables
between switches to avoid creating a loop.
• You can create up to eight trunks on a switch, with up to eight ports per trunk.
• The ports at both ends of a connection must be configured as trunk ports.
• When configuring static trunks on switches of different types, they must be compatible
with the Cisco EtherChannel standard.
• The ports at both ends of a trunk must be configured in an identical manner, including
communication mode (i.e., speed, duplex mode and flow control), VLAN assignments,
and CoS settings.
• Any of the Gigabit ports on the front panel can be trunked together, including ports of
different media types.
• All the ports in a trunk have to be treated as a whole when moved from/to, added or
deleted from a VLAN.
• STP, VLAN, and IGMP settings can only be made for the entire 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.
