Make Permanent IP address to a specific MAC addresses(remember)

[jackolantern66666]

hello

i have cisco 860 router

i have an DHCP service working on it.

when i plug a two devices onto a Lan network it getting IP addresses from the DHCP

but if i replace a "broken" device with "another" device( so total devices on my LAN network remains always the same) the "another" device getting the IP address of a "broken" device. and that i don't want to be. I want a permanent IP address to a specific MAC address. I don't want my IP addresses will hang around in my network. because i am working on some project that i must make "restart" to all Devices on my network. and every restart a different device getting a different IP address.

ho can i configure it?

is not it called "remember" command??

conf t

ip dhcp pool poolname

remember

?

You have to configure exclusion for your Ip address:

Router(config)#ip dhcp excluded-address X.X.X.X (Your ip address)

and configure the address like a static IP in your PC.

well thank you but it does not that i want to do , running around the all network and configure static IP. i want to make it simlier. like i have already configured "infinite" to the pool. but may be i need to add also "remember" to the pool?

Well you can try to do this:

ip dhcp pool TReservation

host X.X.X.X (IP address)

hardware-address aaaa.bbbb.cccc (MAC address)

client-name Test_User

what does it means "client-name"? I don't need a names here. I am only talking about MAC and IP addresses. I want the device will keep it's IP address permanently even if the device is being reset.

[Diana Karolina Rojas]

"client-name" command is only for administration and organization. In my last answer I told you the commands you need to do what you want:

ip dhcp pool Reservation (Pool name)

host X.X.X.X (IP address)

hardware-address aaaa.bbbb.cccc (MAC address)
