Make a link aggregation connection
Before you make a physical link aggregation connection to another network device
(usually a router or another switch) that also supports link aggregation, you must first
set up a LAG on the switch. If you do not, the LAG cannot take effect. Whether a LAG
on the switch functions to support increased bandwidth or fault tolerance depends on
the LAG configuration on the other network device.
All ports that participate in a LAG (that is, the ports on both devices) must use the same
speed, full duplex mode, and flow control setting. For information about changing these
settings on the switch, see Manage
individual port settings on page 27.
To make link aggregation connections between the switch and another network
device:
Using Ethernet cables, connect each port that must be a member of the LAG on the
switch to each port that must be a member of the same LAG on another network
device.
The port numbers on the other network device do not matter as long as:
•
The ports on the other network device are members of the same LAG.
•
The LAG consists of the same total number of ports.
•
The ports use the same speed, full duplex mode, and flow control setting as the
ports in the LAG on the switch.
Set up a static link aggregation group
Set up a static link aggregation group (LAG) to combine multiple Ethernet links into a
single logical link between two networked devices.
For a LAG to function, you must:
•
Set up the LAG on the switch, as described in this task.
•
Connect the ports that must be members of the LAG on the switch to the ports that
must be members of the LAG on another device in your network (see Make
a link
aggregation connection on page 58).
•
Enable the LAG on the switch (see Enable a link aggregation group on page 61) and
on the connected device.
To set up a link aggregation group on the switch:
1.
Open a web browser from a computer that is connected to the same network as the
switch or to the switch directly through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
