Instruction Manual

The device supports the following Aggregation links :
•
Static LAGs (Port Trunk):
Force aggregated selected ports to be a trunk
group.
•
Link Aggregation Control Protocol (LACP) LAGs:
LACP LAG negotiate
Aggregated Port links with other LACP ports located on a different device.
If the other device ports are also LACP ports, the devices establish a LAG
between them.
The Link Aggregation Control Protocol (LACP) provides a standardized means
for exchanging information between Partner Systems that require high-speed
redundant links. Link aggregation lets you group up to eight consecutive ports
into a single dedicated connection. This feature can expand bandwidth to a
device on the network. LACP operation requires full-duplex mode. For more
detailed information, refer to the IEEE 802.3ad standard.
Port link aggregations can be used to increase the bandwidth of a network
connection or to ensure fault recovery. Link aggregation lets you group up to
8 consecutive ports into a single dedicated connection between any two of
the
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, etc.).
•
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.
