ports into a single dedicated connection between any two industrial managed switches
or other Layer 2 switches. However, before making any physical connections between
devices, use the link aggregation configuration menu to specify the link aggregation on
the devices at both ends. When using a port link aggregation, note that:
• The ports used in a link aggregation must all be of the same media type (RJ45, 100
Mbps fiber).
• The ports that can be assigned to the same link aggregation have certain other
restrictions (see below).
• Ports can only be assigned to one link aggregation.
• The ports at both ends of a connection must be configured as link aggregation
ports.
• None of the ports in a link aggregation can be configured as a mirror source port
or a mirror target port.
• All of the ports in a link aggregation have to be treated as a whole when moved
from/to, added or deleted from a VLAN.
• The Spanning Tree Protocol will treat all the ports in a link aggregation as a
whole.
• Enable the link aggregation prior to connecting any cable between the switches
to avoid creating a data loop.
• Disconnect all link aggregation port cables or disable the link aggregation ports
before removing a port link aggregation to avoid creating a data loop.
It allows a maximum of 10 ports to be aggregated at the same time. The industrial
managed switch supports Gigabit Ethernet ports (up to five groups). If the group is
defined as a LACP static link aggregationing group, then any extra ports selected are
placed in a standby mode for redundancy if one of the other ports fails. If the group is
defined as a local static link aggregationing group, then the number of ports must be
the same as the group member ports.
The aggregation code ensures that frames belonging to the same frame flow (for
example, a TCP connection) are always forwarded on the same link aggregation
member port. Reording of frames within a flow is therefore not possible. The
aggregation code is based on the following information:
• Source MAC
• Destination MAC
• Source and destination IPv4 address.
• Source and destination TCP/UDP ports for IPv4 packets
Normally, all five contributions to the aggregation code should be enabled to obtain the
best traffic distribution among the link aggregation member ports. Each link aggregation
may consist of up to 10 member ports. Any quantity of link aggregations may be
configured for the device (they are only limited by the quantity of ports on the device).
To configure a proper traffic distribution, the ports within a link aggregation must use
the same link speed.
