IP to MAC Binding

[Hamidsattarrana]

Hi!

How can I configure IP to MAC binding on cisco 3800 series?

Thanks.

Not sure what you looking here, you looking 3800 act as DHCP and have static DHCP with MAC

or you like to ARP entry for IP with MAC

if you looking IP and MAC here is an example :

Try with the following command

arp  10.10.10.10  xxx.yyy.zzz   << change the IP and MAC-based on the requirement of original IP and MAC)

Hi!
Cisco 3825 Router is acting as DHCP server & responsible for handing out IP address to devices in network. I want to reserve IP address for all host in the network so I think IP to MAC binding on router would be great? But we have almost 250 users in our network, so I can't do it manually for each mac address in our network.

If you have all the MAC Address of the User PC, you do not have any other option adding manually one time.

first you need to exclude the IP range from DHCP Pool

ip dhcp excluded-address  XXXXXXX
ip dhcp pool PC-!
     host 10.10.10.10. 255.255.255.0   <--- change as per requirement
      client-identifier 1234.5678.abcd  < change as per requirement

ip dhcp pool PC-2
     host 10.10.10.11. 255.255.255.0 <--- change as per requirement
      client-identifier 1234.5678.abcd < change as per requirement
