dhcp-tags (Adjustment Control Profiles)


Hierarchy Level


Configure the shaping rate adjustment controls for the DHCP tags application. DHCP tags are supported for session negotiation for DHCPv4 and DHCPv6 over IP demux and VLAN demux interfaces. This means that shaping rates received from DHCP option 82 in the DISCOVER message or DHCPv6 option 17 in the SOLICIT can be used to apply a shaping rate to the logical interface.


Single-session dual-stack DHCP is not fully supported; for example, when rates vary between the individual DHCP sessions during negotiation.

    • adjust-less—Adjust the shaping rate if it is less than the configured value.

    • adjust-less-or equal—Adjust the shaping rate if it is less than or equal to the configured value.

    • adjust-never—Do not perform rate adjustments.
