Managed Industrial L2 Switch
77
• 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,
and duplex mode and flow control settings.
• Configure trunk groups or LACP before you connect the Ethernet switch to
avoid causing network topology loops.
System Priority:
The switch with the lowest system priority (and lowest port number if system priority is
the same) becomes the LACP “server”. The LACP “server” controls the operation of LACP
setup. Enter a number to set the priority of an active port using Link Aggregation Control
Protocol (LACP), the smaller the number, the higher the priority level.
System ID:
The LACP system ID is the combination of the LACP system priority value and the MAC
address of the router.
Administrative Key:
The administrative key defines the ability of a port to aggregate with other ports. A
port's ability to aggregate with other ports is determined by these factors:
• Port physical characteristics, such as data rate, duplex capability, and
point-to-point or shared medium.
• Configuration restrictions that you establish.
Port Priority:
The port priority determines which ports should be put in standby mode when there is a
hardware limitation that prevents all compatible ports from aggregating.
Default Settings:
The default System Priority is 32768.
The default group LACP state is disabled for all groups.
