When a DHCP server is added to IPAM, it shows the number of DHCP scopes discovered after successfully validating the credentials. But after clicking Save, the scopes are not added to the list.
All versions of IPAM
Note: Before doing any work on your Cisco routers, make sure that you have a current backup, as this makes a permanent change to your router.
Add the network address and subnet mask while creating DHCP pool in Cisco devices.
Execute the following commands in config mode on the Cisco Router:
# These 4 commands remove the pools:
no ip dhcp pool Tananger.Desktop
no ip dhcp pool Tananger.Voice
no ip dhcp pool Tananger.PagingGateway
no ip dhcp pool Dymo.Printer
# The below commands re-add the same scopes, they are just re-arranged
ip dhcp pool Dymo.Printer
host 192.168.44.230 255.255.255.0
ip dhcp pool Tananger.PagingGateway
host 10.10.44.9 255.255.255.0
ip dhcp pool Tananger.Desktop
network 192.168.44.0 255.255.255.0
dns-server 10.101.2.22 10.101.2.23 10.100.2.20
option 150 ip 10.44.100.3 10.101.10.2
ip dhcp pool Tananger.Voice
network 10.10.44.0 255.255.255.0
option 150 ip 10.101.10.2 10.200.10.3
dns-server 10.101.2.23 10.100.2.20
There are four pools defined in the Cisco router. But the host declaration pools are not recognized as separate pools. Instead, the host declaration appears as a reservation within the scope containing the complete network.
The DHCP pools are configured without the network IP and subnet mask. IPAM will not accept the DHCP pool without the network and mask value.
