IOS

Some devices in my network are still running with Cisco IOS (no, not the other IOS which had to be bought in order to be able to this name), so sometimes I have to dig back into the network configuration stuff.

When switching now my network storage, I had to reserve a new IP address for that device. Having it jumping around in the network and hiding behind unknown ip addresses is just now allowed.

So be defining my dhcp ip pool for the device I could make sure it stays on its IP address:

ip dhcp pool storage
   host 10.0.0.15 255.255.255.0
   client-identifier 0100.23f8.2ca8.d4
   client-name storage

Only thing left: drop the current ip address from the DHCP resource pool and switch it over to the new one after the next restart.

fw#clear ip arp 10.0.0.12

An overview about the current DHCP release:

fw#sh ip arp
