I have a Windows Server 2016 DHCP setup on my first switch. The DHCP server has LAG setup on 2 ports with LACP enabled. The devices(pcs,laptops,printers) on the first switch all are able to get DHCP addresses from the server and are pingable. My 2nd switches devices are not able to receive the addresses from the DHCP server. I have a trunk setup between the 2 switches using the XG ports allowing Vlan 1 on both interfaces. The devices on the 2nd switch cant ping the DHCP server but can get out to the internet if I do a static address.
My switch 1 trunk port configuration is as follows
interface TengigabitEthernet1/0/2
spanning-tree disable
switchport mode trunk
switchport access vlan none
switchport protected-port
switchport trunk native vlan none
switchport trunk allowed vlan remove 3-4094
macro description " no_switch"
no macro auto smartport
My switch 2 trunk port configuration is as follows - This connects to switch 1
spanning-tree disable
switchport mode trunk
switchport access vlan none
switchport protected-port
switchport trunk native vlan none
switchport trunk allowed vlan remove 3-4094
macro description " no_switch"
no macro auto smartport
I have a feeling I am overlooking something simple but cant figure it out. I appreciate the help.

Hello,
these look like SG switches. The easiest way to configure the trunks is probably to use the 'switch' macro on the trunk ports, and the 'desktop' macro on the access ports. Can you give that a try (page 184 of the attached guide) ?
