This topology is as follows.
The version of Eudemon200E-X is V300R001C00SPC900.
The configuration related with DHCP Server is as follows:
dhcp server forbidden-ip 10.3.0.1 10.3.6.255
dhcp server forbidden-ip 10.3.10.0 10.3.255.255
dhcp server ip-pool 1
network 10.3.0.0 mask 255.255.0.0
description Connected to HQ Users
ip address 10.3.10.11 255.255.0.0
That means that the valid range for the hosts to pick up IP addresses is from 10.3.7.0 to 10.3.9.255
From the pervious, the customer can conclude that the valid IPs that can be assigned to the hosts are approximately 255*3 = 765 IP.
The problem is that the customer found no available IPs to withdraw from the DHCP pool. When he used the command “display dhcp server free-ip” he found that there was only on IP address available in the free-ip link.
