# Listener Configuration, Select Protocols

The listener receives client requests at a protocol address specified in the listener.ora file. Clients sending a request are also configured with the same protocol address.

Select the protocol(s) from the Available Protocols list to create a protocol address for the listener. The protocol address is stored in the listener.ora file.

To select protocols to use:

1. Select protocol(s) from the Available Protocols list, and then choose the right-arrow button. The selected protocol(s) move to the Selected Protocols list.

2. Order the protocols according to which protocols you expect clients to use the most with the up- or down-arrow buttons.
3. Choose Next. Based on your choice of protocol(s), you will be asked for protocol parameter information.

| Note: If you decide to later change your choice of protocols, use the Net8 Assistant to make any modifications to listener configuration.
