ONFIGURATION

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 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 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 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.
