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 where bottlenecks exist, as well as providing a fault-
tolerant link between two devices. You can create up to six trunks at a time.
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 switch as LACP,
as long as they are not already configured as part of a static trunk. If ports on another device are also
configured as LACP, the switch and the other device will negotiate a trunk link between them. If an LACP
trunk consists of more than four ports, all other ports will be placed in a 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 six 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.
