VLAN DHCP Vendor ID how to use it on Ubuntu?

Question

DHCP

What at the moment:
Huawei ONU optics with rj-11 for SIP connection.
WAN VLAN 511/5 in route WAN
IPv4 mode in DHCP client mode
Vendor ID: dslforum.otg
User ID: parameter not set

What I want to do:
Install asterisk with a connection to the provider.
I assume that WAN VLAN 511/5 needs to turn the bridge to LAN1 port, Ubuntu will be behind it, but here you need to set the MAC network card from Huawei + Vendor ID. And what is a Vendor ID anyway?
Vendor ID according to one information is for a DHCP server to access a pool of a certain network, from another resource they say that this is a MAC address?
