- Tracy Yang
The set protocols dhcp6 snooping option18 interface-id command configures the format of sub-option interface ID inserted into the Option 18 field for DHCPv6 snooping.
NOTE: The sub-option interface ID is applied to VLANs where option-policy is set to “insert” or “replace”.
Command Syntax
set protocols dhcp6 snooping option18 interface-id <port-index | port-name | port-description>
Parameters
Parameter | Description |
interface-id <port-index | port-name | port-description> | Specifies the type of interface ID in the Option 18 field. The value could be port-index, port-name or port-description. By default, the sub-option interface ID is not configured which means interface ID is not enabled. |

- When “port-description” is selected, the format of the interface ID is “VLAN ID + port description”. The value of “port-description” can be set by the following commands:
set interface aggregate-ethernet <lag_name> description <description>
