What is Manual DHCP Binding or Static DHCP binding?
The DHCP server assigns the client an available IP address automatically and then creates an entry in the binding table. However, the administrator can manually create an entry for a client. Manual bindings are useful when you want to guarantee that a network device receives a specific IP address.
Configuration
Dynamic Pool Configuration
|
Command |
Explanation |
|---|---|
DELL# configure |
Enter Configuration Mode |
DELL(conf)# ip dhcp server |
Enter DHCP mode |
DELL(config-dhcp)# pool <POOL NAME> |
Create the DHCP Pool |
DELL(config-dhcp-D-POOL)# network <Network/subnet mask> |
Specify the IP address |
DELL(config-dhcp-D-POOL)# default-router <Default Router IP> |
Specify default-router |
DELL(config-dhcp-D-POOL)# dns-server <DNS server IP> |
Specify DNS-Server |
Static Pool Configuration
|
Command |
Explanation |
|---|---|
DELL# configure |
Enter Configuration Mode |
DELL(conf)# ip dhcp server |
Enter DHCP mode |
DELL(config-dhcp)# pool <POOL NAME> |
Create DHCP Pool |
DELL(config-dhcp-S-POOL)# host-address <IP address> |
Specify IP address |
DELL(config-dhcp-S-POOL)# hardware-address <Mac address> |
Specify the client hardware address |
DELLconfig-dhcp-S-POOL)# default-router <Default Router IP> |
Specify default-router (Optional) |
DELL(config-dhcp-S-POOL)# dns-server <DNS server IP> |
Specify DNS-Server (Optional) |
Activate DHCP SERVER

Command |
Explanation |
|---|---|
DELL# configure |
Enter Configuration Mode |
DELL(conf)# ip dhcp server |
Enter DHCP mode |
DELL(config-dhcp)# no disable |
Activate DHCP Server |
Sample Configuration
Consider the below example where a Client with mac address 11:22:33:44:55:66 must receive IP address 10.0.0.100 from the DHCP server.
Sample Configuration
DELL# configure DELL(conf)# ip dhcp server DELL(config-dhcp)# pool DYNAMICPOOL DELL(config-dhcp-DYNAMICPOOL)# network 10.0.0.0/24 DELL(config-dhcp-DYNAMICPOOL)# default-router 10.0.0.1 DELL(config-dhcp-DYNAMICPOOL)# dns-server 8.8.8.8 DELL(config-dhcp-DYNAMICPOOL)# exit DELL(config-dhcp)# DELL(config-dhcp)# pool STATICPOOL DELL(config-dhcp-STATICPOOL)# host-address 10.0.0.100 DELL(config-dhcp-STATICPOOL)# hardware-address 10:22:33:44:55:66 DELL(config-dhcp-DYNAMICPOOL)# exit DELL(config-dhcp)# DELL(config-dhcp)# no disable

DHCP CONFIGURATION
To verify the DHCP server configuration and pool details use below command:
DELL# show ip dhcp configuration pool
Sample output
DELL# show ip dhcp configuration pool Pool Name : DYNAMICPOOL Pool Type : Dynamic Domain Name : Lease Time : 1Day 0Hrs 0Mins DNS Servers : 8.8.8.8 Default Routers : 10.0.0.1 Network : 10.0.0.0 255.255.255.0 Pool Name : STATICPOOL Pool Type : Manual Domain Name : Lease Time : 1Day 0Hrs 0Mins DNS Servers : Default Routers : Hardware Address : 10:22:33:44:55:66 Hardware Address Type: Ethernet Host : 10.0.0.100 0.0.0.0
Binding
To verify the IP address provided by DHCP server use below command:
DELL# show ip dhcp binding Sample output DELLEMC#show ip dhcp binding IP address Hardware address Lease expiration Type 10.0.0.100 10:22:33:44:55:66 infinite Manual Total number of entries in the table: 1
Points to remember
- You must have a dynamic pool range in that network for the static pool to work
- Manual bindings can be considered single-host address pools. There is no limit on the number of manual bindings,
- We can only configure one manual binding per host.
- Ensure that we are using valid host IP within the subnet range as the host IP.
