Usage Guidelines

Usage Scenario

The suboption command is used on DHCPv6 servers. Run the vendor-specific command to enter the vendor-defined mode. In this mode, configure the vendor-defined DHCPv6 options. The DHCPv6 device can carry vendor-defined options such as the TFTP server name and address, and the configuration file of the device.

The suboption command configures vendor-defined DHCPv6 sub-options.

Precautions

A maximum of 16 vendor-defined sub-options can be configured in the vendor-defined mode view.
