Doubling the bandwidth of the link between switches series1920

MarekStel

Dear all,
I based the network backbone on zyxel1920 switches. Due to the high load on the network, is it possible to double the bandwidth by connecting two switches using two parallel 1GBps links? (where to look for such a configuration).
Is it possible to configure a network with a ring on these switches (each switch connected on two sides).

Please advise where to look in the configuration. Any keywords...

BR,

Mark

Hi @MarekStel ,

Please refer to this article to know how to configure Link Aggregation for your GS1920 switches:

Is it possible to configure a network with a ring on these switches (each switch connected on two sides).

To better support you, could you share more detail about the scenario/ application? If possible, please help to draw the typology.

You could use spanning tree to avoid loops when creating a ring. Read about STP priority as well if you connect serveral swiches.

You could also do link aggregation as suggested above to create a logical 2 GBps link out of 2 1GBps physical links. But note that you cannot aggregate the bandwidth of those links to one big pipe. I.e you cannot for example create a data session of more than 1GBps of that 2GBps logical link. But you probably knew that.
