DHCPv6 Support

In LoadMaster firmware version 7.2.52 (and LTS version 7.2.48.2) DHCPv6 support was added.

On initial deployment, DHCPv4 and DHCPv6 both run to attempt to obtain an IP address. If the LoadMaster obtains an IP address using DHCP, take note of it because this is how you will access the LoadMaster. If the LoadMaster does not obtain an IP address using DHCP the static IP address of 192.168.1.101 is assigned and the LoadMaster must be manually configured using the console.

After obtaining an initial IP address, DHCP is disabled and will not run after subsequent reboots.

To enable DHCPv6 after initial deployment, in the LoadMaster User Interface (UI), go to System Configuration > Logging Options > System Log Files > Debug Options and select the Enable DHCPv6 Client check box. When this option is enabled, the DHCPv6 client runs on the primary interface. This provides the capability to obtain an IPv6 address on boot. If you want DHCPv6 to be run on every boot, keep this option enabled. However, this is a long running process and it keeps running in the background when it is enabled so if you only need an IPv6 address to be assigned and you do not need to renew and release the IPv6 address you should disable this option after the IPv6 address is assigned.

For further information on initial LoadMaster deployment, refer to the relevant Installation Guide on the Kemp Support Center.

Application Programming Interface (API) Details

To check if DHCPv6 is enabled or disabled, run the following RESTful API command:

/access/get?param=dhcpv6

To enable or disable DHCPv6, run the following RESTful API command:

/access/set?param=dhcpv6&value=<0/1>

For further details on the RESTful API in general, refer to the RESTful API Interface Description document.

For PowerShell help, run the Get-Help command for the relevant commands.
