Configuring DHCP Authority Ranges
The DHCP Authority ranges that you define for an interface dictate what
addresses are protected by the authority feature. The DHCP Authority IP
address ranges that you define must fall within the range of IP addresses as
allowed by the IP interface (as dictated by the network mask for that IP
interface).
For example, if the physical interface has an IP interface of 172.16.19.1with
a mask of 255.255.255.0 installed, you can define a DHCP Authority range
from 172.16.19.2 to 172.16.19.254, or any subset of that IP address range.
You can define up to 200 IP address ranges per physical interface.
The DHCP Authority ranges take effect upon the next DHCP server exchange
with the client. This means that after you configure a range, you should
reboot the client so that the ARP entry for that client’s MAC address is
updated.
To configure DHCP Authority ranges, follow this procedure:
1. Navigate to Network Browser > GroupName > ChassisName > Cuda
Chassis Manager > Configuration > IP > DHCP.
2. Click the Summary tab.
3. In the Summary window, select the row that includes the interface on
which you want to configure DHCP Authority.
4. Click the DHCP Authority tab.
