I would like laptops to get the same IP address from the DHCP pool every time they join the network. Is there a way of binding the laptop MAC address to an IP address so the same IP address is given to the laptop every time?

Hi Jaime,
Yes that is very well possible on cisco routers/switches working as DHCP server. Can you confirm is you have cisco switches/routers working as DHCP server or some external server?

If you want to configure manual bindings, create a host pool for the 10.10.135.111 address. For example:
ip dhcp pool STATIC
host 10.10.135.111 255.255.255.0
Client-identifier (aabb.ccdd.eeff ...)
default-router 10.10.135.1
domain-name domain.com
option 150 ip 172.16.1.11
dns-server 172.16.1.40 172.17.1.250
netbios-name-server 172.16.1.40 172.17.1.250
ip dhcp pool Data
network 10.10.135.0 255.255.255.0
default-router 10.10.135.1
domain-name domain.com
option 150 ip 172.16.1.11
dns-server 172.16.1.40 172.17.1.250
netbios-name-server 172.16.1.40 172.17.1.250
Below is the URL that has some additional details.

hi
An address binding is a mapping between the IP address and MAC address of a client. The IP address of a client can be assigned manually by an administrator or assigned automatically from a pool by a DHCP server.
Manual bindings are IP addresses that have been manually mapped to the MAC addresses of hosts that are found in the DHCP database. Manual bindings are stored in NVRAM on the DHCP server. Manual bindings are just special address pools. There is no limit on the number of manual bindings, but you can only configure one manual binding per host pool.
