The LAG (Link Aggregation Group) combines several physical ports to create a single high-bandwidth data path as well as to implement the traffic load shared among the member ports in a group. 

LAG enhances the connection reliability and efficiency. 

**Important:**\
The first port that joins an LAG sets its settings to default settings of the LAG. All ports that are in an LAG have the same settings. 

**Requirement:**

[Connection to the web interface](/network/key_access_web_interface/)

1. Click **Edit Ports / Groups**.
2. To change the names of the LAGs in the table **LAG Names**, click in the row and type the name.

_Edit LAG names_

3.  Click **Apply settings and stay where you are** or **Apply settings and leave edit**. 

The names of the LAGs have been adjusted and saved in the startup configuration. 

4. Assign a port to an LAG in **Choose LAG**:\
   -Click the LAG you would like to assign a port to.\
   -A green dot is displayed in the LAG.

**Hint:**\
-The ports that are connected to one and the same LAG must have the same LAG ID in a switch.\
-The ports in a counterpart switch must have an identical LAG ID as well. This LAG ID does not have to correspond another switch´s LAG ID.\
-For reasons of clarity, we recommend you use the same LAG IDs for the same LAG in different switches.
