Statement introduced in Junos
OS Release 9.6.
Support at the [edit ... dhcpv6] hierarchy levels
introduced in Junos OS Release 11.4.
Statement introduced in Junos OS Release 12.3 for EX Series
switches.
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. Use the statement at the [edit ... dhcpv6] hierarchy levels to configure DHCPv6 support.
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.
