interface-description (DHCP Local Server)


Hierarchy Level


Specify that the interface description for the device (physical) interface or the logical interface is concatenated with the username during the subscriber authentication or DHCP client authentication process. Use the statement at the [edit ... dhcpv6] hierarchy levels to configure DHCPv6 support.

The interface description is configured using the description statement at the [edit interfaces interface-name] hierarchy level. The delimiter is configured with the delimiter statement at the [edit system services dhcp-local-server ... username-include] hierarchy level.


The username delimiter must not be a character that is part of the interface description. For example, if the description includes a forward slash (/), then the delimiter must not be a forward slash. The default delimiter is a period.



Use the text description configured for the device (physical) interface.


Use the text description configured for the logical interface.
