IPv6 Interface Configuration on SFE/SGE Series Stackable Managed Switches

Objective

The objective of this document is to help configure IPv6 Interface settings on SFE/SGE Series Stackable Managed Switches. These settings allow you to add IPv6 addresses and an IPv6 interface. IPv6 addresses are used to identify a network interface of a computer.

Applicable Devices

• SFE/SGE Series Stackable Managed Switches  

Software Version

• v3.0.2.0 

IPv6 Interface Settings

Step 1. Log in to the web configuration utility and choose System > System Management > IP Addressing > IPv6 Configuration > IPv6 Interface. The IPv6 Interface page opens:

Step 2. In the 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 3. In the DAD Attempts field, enter the number of consecutive neighbor solicitation messages that the router sends from the IPv6 interface. The duplicate address detection (DAD) feature helps to verify that a new unicast IPv6 address is unique in the network.

The Interface table displays the following fields: 

• IPv6 Type — It displays whether the IPv6 type is link local or global unicast. 

• IPv6 Address — The IPv6 address assigned to the interface is displayed.

• Prefix — The IPv6 prefix length is displayed. The value is between 5 to 128.

• DAD Status — The current DAD status is displayed. The possible statuses are:

- Duplicate — This means that the same IPv6 address is being used by another host on the network.

- Preferred — This means that the DAD status is active.

- Tentative — This means that the system is still in process to check for duplication. 

Step 4. (Optional) To delete an existing IPv6 address interface, check on the respective check box and then click Delete.

Add an IPv6 Address 

Step 5. Click Add to add a new IPv6 Address Interface. The following window opens:

The IPv6 Interface field displays the selected interface.

Step 6. In the IPv6 Address Type  field, click the radio button of the desired IPv6 address type. 

• Link Local — To communicate on the same subnet.

• Global — To communicate globally.

Step 7. In the IPv6 Address field, enter the IPv6 address that should be assigned to the interface. It should be in the hexadecimal format using 16-bit values between colons.

Step 8. In the Prefix Length field, enter the prefix length of the IPv6 address. It should be between 5 and 128. The value is 64 if EUI-64 parameter is used.

Step 9. Click Apply to save the configuration. 

Add an IPv6 Interface

Step 10. Click Add to add a new IPv6 Interface. The following window opens:

Step 11. In the IPv6 Interface field, choose a VLAN number from the drop-down list, to which the DAD attempt settings should be applied.

Step 12. In the Number of DAD Attempts, enter the desired number of DAD attempts.

Step 13. 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
