Working with listeners

IBM Cloud® Network Load Balancer for VPC (NLB) listeners are used to configure how the load balancer receives your traffic. The attributes that you can define on a listener are protocols, ports, and pools.

You can configure listeners when creating a network load balancer, or later with the following procedure:

1. From your browser, open the IBM Cloud console and log in to your account.

2. Select the Navigation menu , then click Infrastructure > Network > Load balancers.

3. Click the NLB that you want to change.

4. On the network load balancer details page, click the front-end listeners tab, then select the listener that you want to edit.

5. Select the new options for your listener. You have the following options:

   • Protocol: The network protocol for the inbound customer traffic.
   • Port: The port that the load balancer receives your inbound customer traffic.
   • Back-end pool: The pool the load balancer distributes to the inbound customer traffic.

When you use the UI, you must create a pool before you create a listener. You cannot set the pool of an existing listener to empty.
