DHCP not working

Can you show a screen shot of your dhcp config?

please

What is your goal in having /22 instead of /24?  Do you need the additional subnets?  /24 will provide 256 addresses, minus the start point of 20 so 236 I believe.  

I only ask because I am curious but does the interface and zone match this?   In terms of subnetting?

Thanks for the reply and answers , well I am guessing /22 gives me more address which is 10.16.20.0 to .23.0 than /24 which will be 10.16.20.0 to .20.255. Correct me if am wrong please and again could that be the problem why it’s not leasing IPs ??

I can change it back to /24 if u think that wud solve the problem.

/22 will give you additional subnets were /24 will keep all leases on the same subnet.  I bring this up because on your screen shot it shows port 1 for interface, which is set to 10.16.20.1.  I would check that the interface port under networking ---> interfaces is also set to 10.16.20.1/22 or /24 or whatever subnetting you are trying to achieve.  Basically the interface has to support the same IP's as the DHCP.  But if I were you I would make it as simple to work through as possible and for now stick with /24, get the 230 devices working and if you need more go from there.

Hi elmooo,

I would recommend to check if the DHCP request is initiated and responded by XG. Please take a packet capture on the host mac address, you use CLI and go to option 4 and enter the command with the command shown below.

tcpdump host aa:bb:cc:11:22:33
