Creating Trunk Groups
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

• Finish configuring port trunks before you connect the corresponding network
cables between switches to avoid creating a loop.
• You can create up to four trunks on the 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.
• 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.

The switch supports both static trunking and dynamic Link Aggregation Control
Protocol (LACP). Static trunks have to be manually configured at both ends of the
link, and the switches must comply with the Cisco EtherChannel standard. On the
other hand, LACP configured ports can automatically negotiate a trunked link with
LACP-configured ports on another device. You can configure any number of ports
on the
static trunk. If ports on

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,
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:
