If you are setting up a dhcp server on the securestack give this article a read.
How to configure DHCP server on Securestack
I tried this article, but i could not.

I did not understand these parts below.
set dhcp pool host-pool1 client-identifier 01:00:80:C7:13:3A:DB 
set dhcp pool host-pool1 host 10.10.10.25 255.255.255.0 

set dhcp pool host-pool2 client-identifier 01:00:18:8B:C9:16:5F 
set dhcp pool host-pool2 host 10.10.10.26 255.255.255.0
set dhcp pool shoretel option 156 ascii ftpservers=192.168.1.101,layer2tagging=1,vlanid=110

You'd look up the explanation in the CLI refernce guide...
https://documentation.extremenetworks.com/Active_Archive/B-Series/B-5/SW_Doc/9034706-01_B5_CLIRef_FW...

1) Use this command to configure an IP address and network mask for a manual DHCP binding = so they always get the same IP
#set dhcp pool host-pool1 client-identifier 01:00:80:C7:13:3A:DB
#set dhcp pool host-pool1 host 10.10.10.25 255.255.255.0 
set dhcp pool host-pool2 client-identifier 01:00:18:8B:C9:16:5F 
set dhcp pool host-pool2 host 10.10.10.26 255.255.255.0


2) Just a DHCP scope with special options for shoretel phones = in that case the phone get's the ftp (to get the config file) and a VLAN ID - but that is for that phone model and not all vendors use the same format and options.
#set dhcp pool shoretel option 156 ascii ftpservers=192.168.1.101,layer2tagging=1,vlanid=110
Ok, I understood the example above.
I want to create two VLANs on the switch and one DHCP server. Where the DHCP server will distribute ips over VLAN 2. I don't know how to use option 132 in DHCP on this switch. Thanks.
