How do we create multiple DHCP scope exceptions in 1570 Appliance(R81.10)?

Anaz — Thu, 09 Feb 2023 04:27:07 GMT

Hi All,

I am trying to create multiple DHCP scope exceptions for a particular network. Eg. I have a network 10.100.1.0/24 on which I need DHCP scope exceptions from 10.100.1.50-10.100.1.65 and 10.100.1.150-10.100.1.240.
How would I do this?

Have you tried the following CLI option without success?

Hi Chris,

Thank you for sharing that.

Let me try the following commands.

set interface "LAN1.11" ipv4-address "10.100.1.1" subnet-mask "255.255.255.0"
set dhcp server interface "LAN1.11" dns "auto"
set dhcp server interface "LAN1.11" lease-time "4"
set dhcp server interface "LAN1.11" include-ip-pool "10.100.1.1-10.100.1.254
add address-range name VLAN11 start-ipv4 10.100.1.50 end-ipv4 10.100.1.65 dhcp-exclude-ip-addr on
add address-range name VLAN11.1 start-ipv4 10.100.1.150 end-ipv4 10.100.1.246 dhcp-exclude-ip-addr on

Regards,

I tested it in Test Environment and found it to be working. I will be implementing it in Production next week.
