Click OK and return to Link Aggregation menu.
NOTE: All trunking ports in the group must be members of the same VLAN, and their
Spanning Tree Protocol (STP) status and QoS default priority configurations must be
identical. Port locking, port mirroring and 802.1X cannot be enabled on the trunk group.
Furthermore, the LACP aggregated links must all be of the same speed and should be
configured as full duplex.
4.4.3.3 LACP Port Configuration
The Managed Switch supports dynamic Link Aggregation Control Protocol (LACP) which is
specified in IEEE 802.3ad. Static trunks have to be manually configured at both ends of the link.
In other words, LACP configured ports can automatically negotiate a trunked link with LACP
configured ports on other devices. You can configure any number of ports on the Managed Switch
as LACP, as long as they are not already configured as part of a static trunk. If ports on other
devices are also configured as LACP, the Managed Switch and the other devices 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.
Click the option LACP Port Configuration from the Link Aggregation menu and then the screen
page is shown below. It is necessary to set up both “Key Value” and “Role” two options from the
pull-down menu of Select Setting for the designated ports when creating a LACP(dynamic Link
Aggregation) group. For more details on these settings, please refer to the following description in
this section.
