 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 16 ports to be aggregated at the same time. The Managed Switch support Gigabit Ethernet ports (up to
12 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 5 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 16 member ports. Any quantity of link aggregation s may
be configured for the device (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.
