14.4.1 Dynamic Link Aggregation
This feature is not available on all models.
The switch adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port
trunking.
The switch supports the link aggregation IEEE 802.3ad standard. This standard describes the
Link Aggregate Control Protocol (LACP), which is a protocol that dynamically creates and
manages trunk groups.
When you enable LACP link aggregation on a port, the port can automatically negotiate with
the ports at the remote end of a link to establish trunk groups. LACP also allows port
redundancy, that is, if an operational port fails, then one of the “standby” ports become
operational without user intervention
Please note that:
• You must connect all ports point-to-point to the same Ethernet switch and configure the
ports for LACP trunking.
• LACP only works on full-duplex links.
• All ports in the same trunk group must have the same media type, speed, duplex mode and
flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing
network topology loops.
14.4.2 Link Aggregation ID
LACP aggregation ID consists of the following information:
14.4.3 Configuring Link Aggregation
1 First activate link aggregation in the Switch Setup screen.
2 To open the LACP Conf. screen, right-click on the switch in the Device List Panel, and
click Configuration > Switch Configuration > LACP Conf. to display the
configuration screen.
