6.7.3 Creating Trunk Groups
Multiple links can be created 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. Up to 13 trunks can be created at a time.
The ECN330-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. Any
number of ports on the ECN330-switch can be configured 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 ECN330-switch and the other device
will negotiate a trunk link between them. If an LACP trunk consists of more than
eight 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
