Hi, 

I'm in the process of replacing an ERS4850 with an Extreme 5420, 

I've configured 3 VLANs as per the ERS, Voice/Data and Uplink.  Uplink port is on 1/48

I've tagged all Ports 1-47 for Voice
I've untagged all ports 1-47 for Data. 
1/48 is in the uplink VLAN

-----------------------------------------------------------------------------------------------
data 3165    172.25.25.3 /24 -f------------------------ ANY 0 /103 VR-Default
Link_to_BT 3167 192.168.8.2 /30 -------------------------- ANY 0 /1 VR-Default
voice 3166 172.26.26.3 /24 -f------------------------ ANY 0 /112 VR-Default

The uplink port is 192.168.8.2 and the upstream BT router is 192.168.8.1. 

On the ERS4850. I have the commands 

ip dhcp-relay
ip dhcp-relay option82
ip dhcp-relay fwd-path 172.25.25.3 172.18.24.100
ip dhcp-relay fwd-path 172.25.25.3 172.18.24.100 mode dhcp
ip dhcp-relay fwd-path 172.25.25.3 172.18.24.200
ip dhcp-relay fwd-path 172.25.25.3 172.18.24.200 mode dhcp
ip dhcp-relay fwd-path 172.26.26.3 172.18.24.100
ip dhcp-relay fwd-path 172.26.26.3 172.18.24.100 mode dhcp
ip dhcp-relay fwd-path 172.26.26.3 172.18.24.200
ip dhcp-relay fwd-path 172.26.26.3 172.18.24.200 mode dhcp

What is the XOS equivalent to the above ERS4850 DHCP helpers?

(I'm new to XOS and really need to get a grip on it as I will be replacing all my ERS (BOSS) with XOSs) 

Any help will be greatly appreciated.

Think I got it.  Thanks if you looked. 

Its the terminology from the rest of the world from DHCP relay. 

configure bootprelay vlan data add 172.18.24.100
configure bootprelay vlan data add 172.18.24.200
configure bootprelay vlan voice add 172.18.24.100
configure bootprelay vlan voice add 172.18.24.200
