The objective of this document is to help configure Domain Name System (DNS) Server 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 names and their IP addresses.
• SFE/SGE Series Managed Switches
DNS Server Congifuration
Step 1. At the web configuration utility choose System > System Management > IP Addressing > Domain Name System > DNS Servers . The DNS Servers page opens:
Step 2. In Enable DNS field, check the Enable DNS check box to translate the DNS name into an IP address.
Step 3. In the Default Domain Name field, enter the desired DNS server name.
Type field displays if the type of IP address is Static or Dynamic.
Step 4. In the Remove field, check the Remove check box in order to delete the selected DNS servers, keep it unchecked to maintain the existing list.
The DNS server table displays the following:
• DNS Server — This field displays the IP address of the DNS server.
• Active Server — This field displays the DNS server that is active.
Step 5.(Optional) To delete an existing DNS Server check on the corresponding check box and then click Delete.
Adding DNS Server
Note: At a time only 4 DNS servers can be defined at the utility.
Step 6. Click Add to add a new DNS Server. The Add DNS Server window appears:
Step 7. In the Supported IP format field, click the radio button for the desired IP version.
Note: Follow Step 8 and Step 9 only if you choose version 6 in Step 7 else skip to Step 10.
Step 8. 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 9. 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 10. In the DNS Server IP Address field, enter the DNS Server IP address.
Step 11. In the Set DNS Server Active field, check the Set DNS Server Active check box to make this an active DNS server.
Step 12. Click Apply to save the configuration.
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.
