Is there a way to exclude a range/single ip address from "configure vlan dhcp-address-range xxxx - xxxx"
for example: configure vlan vlan_name dhcp-address-range  -
Can I exclude from being allocated?

I didn't ever work with EXOS, but I guess you are able to configure static DHCP reservations? If so, just reserve for MAC address aa:11:22:33:bb:cc.

I admit it's a workaround but will prevent duplicate IPs.

No, that's not possible. The DHCP server supports only a single continuous range of IP addresses.

The DHCP server implementation was originally meant to provide temporary short-lived IP addresses for Web-based network login, where the final IP address would be provided by a central company-wide DHCP server when the port was moved to the final VLAN.
