The ports at both ends of a connection must be configured as trunk
■
ports.
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.
The ports on both ends of an LACP trunk must be configured for full
■
duplex, either by forced mode or auto-negotiation.
Any of the Gigabit ports on the front panel can be trunked together,
■
including ports of different media types.
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.
If the target switch has also enabled LACP on the connected ports, the
◆
trunk will be activated automatically.
A trunk formed with another switch using LACP will automatically be
◆
assigned the next available trunk ID.
If more than eight ports attached to the same target switch have LACP
◆
enabled, the additional ports will be placed in standby mode, and will
only be enabled if one of the active links fails.
All ports on both ends of an LACP trunk must be configured for full
◆
duplex, either by forced mode or auto-negotiation.
Ports assigned to a common link aggregation group (LAG) must meet
◆
the following criteria:
Ports must have the same LACP administration key. Using auto-
■
configuration of the administration key will avoid this problem.
One of the ports at either the near end or far end must be set to
■
active initiation mode.
