If the target switch has also enabled LACP on the connected ports, the trunk will automatically activate.
l
If more than four ports attached to the same target switch have LACP enabled, the additional ports enter standby mode and will only be enabled if one
l
of the active links fails.
STP, VLAN, and IGMP settings can only be made for the entire trunk through the specified port-channel.
l
To add a port to a static trunk, click the Static toggle button below the port number until the correct trunk number appears. To make a port available for an
LACP trunk, click the LACP toggle button below the port number until an L appears.
NOTICE: All ports on both ends of an LACP trunk must be configured for full duplex, either by forced mode or auto-negotiation.
NOTICE: All ports participating in a trunk should have the same VLAN and CoS settings.
NOTICE: In order for a port to join an existing trunk through LACP, the port's flow control, speed and duplex mode, and autonegotiation settings must
match those of the existing trunk.
