5.9.3 Link Aggregation
[ Switching > L2-Redundancy > Link Aggregation ]
The
Link Aggregation
function lets you aggregate multiple parallel links. The prerequisite is that the
links have the same speed and are full duplex. The advantages compared to conventional
connections using a single line are higher availability and a higher transmission bandwidth.
The Link Aggregation Control Protocol (LACP) makes it possible to monitor the packet-based
continuous link status on the physical ports. LACP also helps ensure that the link partners meet the
aggregation prerequisites.
If the remote side does not support the Link Aggregation Control Protocol (LACP), then you can
use the
Static link aggregation
function. In this case, the device aggregates the links based on the
link, link speed and duplex setting.
Table
Trunk port
Displays the LAG interface number.
Name
Specifies the name of the LAG interface.
Possible values:

Alphanumeric ASCII character string with 1..15 characters
Link/Status
Displays the current operating state of the LAG interface and the physical ports.
Possible values:

up ( lag/… row)
The LAG interface is operational.
The prerequisites are:
– The Static link aggregation function is active on this LAG interface.
or
– LACP is active on the physical ports assigned to the LAG interface, see the LACP active
column.
and
The key specified for the LAG interface in the LACP admin key column matches the keys
specified for the physical ports in the LACP port actor admin key column.
and
The number of operational physical ports assigned to the LAG interface is greater than or
equal to the value specified in the Active ports (min.) column.

up
The physical port is operational.
