Dear all.

1. I want install Vlan database on Core Switch 6850 and Sync Vlan Database to Switch Access 6224 as above picture.
2. I want to deploy DHCP Snooping con Core Switch 6850 and how can it apply to Swtich Access 6224
Remark: DHCP will be installed on firewall (Draytek Virgor 3900)

Any suggest guide - thanks in advance

Where do you want to deploy the DHCP server? On the core or the 6224?

Thanks mr Mohdkw about your response.
I config DHCP Scope VLAN on Firewall (Draytek 3000).
Please suggest me to get it.

Big thanks you.

Is there a solution for this scenario?

I do not think that you can sync vlan databases from 6850 to 6224 (but i must admit i have never tried with gvrp or mvrp).

DHCP should be easy, if you draytek has different pools (uses the correct pool per vlan).

on the 6850 it should be enough to enter

ip helper address <ADDRESSOFDRAYTEK>
ip helper forward delay 0

test that first (e.g. put a client at a vlan 40 port, do you get dhcp .. test at vlan 20 aso..)

or do you really mean DHCP Snooping.
It should be fine to set the port for the draytec as trusted, but here consult the docs, io have not worked with dhcp snooping.
