The objective of this document is to help configure Domain Name System (DNS) Host Mapping on SFE/SGE Series Managed Switches. DNS is a system that converts the user defined domain names into IP address and also maintains the database of the host names and their IP addresses.
• SFE/SGE Series Managed Switches
DNS Host Mapping Configuration
Step 1. At the web configuration utility choose System > System Management > IP Addressing > Domain Name System > Host Mapping . The DNS Host Mapping page opens:
• Host Name — This field displays the user defined domain name.
• IP Address — This field displays the DNS IP address.
Step 2.(Optional) To delete an existing Host Mapping check on the corresponding check box and then click Delete.
Adding Host Mapping
Step 1. Click Add to add a new Host Mapping in the Host Mapping page. The Host Mapping window appears:
Step 2. In the Supported IP format field, click the radio button for the desired IP version.
Note: Follow Step 3 and Step 4 only if you choose version 6 in Step 2 else skip to Step 5.
Step 3. In the IPv6 Address type field, click the radio button for the desired IPv6 address type.
• Link Local — To communicate on the same subnet.
• Global — To communicate globally.
Step 4. In the Link Local Interface field, click the radio button of the desired Interface. For example, If you choose ISATAP, it indicates that the interface is an Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnel.
Step 5. In the Host Name field, enter the desired domain name. It can have upto 158 characters.
Step 6. In the IP Address field, enter the DNS host IP address.
Step 7. In the IP Address (2-4) (Optional) field, enter the other DNS host IP address. At a time 4 IP addresses can be added.
Step 8. Click Apply to save the configuration. Below image shows the added host name and the IP address.
Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file. See Copy Configuration File on SFE/SGE Series Managed Switches for more information on how to do this.
