The Hosts Table feature allows you to edit the /etc/hosts file from the WebUI or through a REST interface. Each line in the hosts file contains one IP address and at least one host name.

Hosts File Example: localhost testux218

This allows applications on the Sonus SBC 1000/2000, such as SIP Signaling Groups, AD, RADIUS, ect to resolve FQDNs when a DNS server is not reachable. We recommend that only a few, very critical, host-IP pairs be stored on the Sonus SBC 1000/2000.

Another use-case is in a pre-deployment scenario in which an administrator wished to divert traffic by mapping the same FQDN to a different IP address. For example, a Sonus SBC 1000/2000 can talk to a Lync server under test before it is added to the production network, using the same FQDN, but with a different IP address.

Working with Host Tables

  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to Protocols > IP > Hosts.

Helpful Tip: To delete an entry, simply select the checkbox next to the entry you wish delete, then click the Delete () icon located at the top of the window.

Creating Entries in the Hosts Table

Changes to the Hosts Table are not dynamically applied. Reboot the Sonus SBC 1000/2000 following any modification to the Hosts Table.
