Release Information

Statement introduced in JUNOS Release 9.6.

Description

Use the textual interface description instead of the interface identifier when creating the agent-circuit-id suboption of the DHCP relay agent option 82.

If you specify that the textual description is used and no description is configured for the interface, DHCP relay defaults to using the interface identifier. The textual description is configured using the description statement at the [edit interfaces interface-name] hierarchy level.

Note: By default, DHCP relay accepts a maximum of 253 ASCII characters. If the textual interface description is longer than 253 characters, DHCP relay drops the packet, which results in the DHCP client failing to bind.

Options

logical—Use the textual description that is configured for the logical interface.

device—Use the textual description that is configured for the device interface.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
