c800 series Static IP Addressing issues

Brandan Giles · ‎03-22-2017

In the following configuration, the assigned DHCP reservation is ignored. See the bindings...the static reservation appears in the binding list, but when the client connects, a new IP address is assigned instead. Any ideas?

sh ver:
Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.3(3)M, RELEASE SOFTWARE (fc2)

config:

ip dhcp pool DA
network 10.0.0.0 255.255.255.0
default-router 10.0.0.1
lease 0 8

!
ip dhcp pool STATIC
host 10.0.0.198 255.255.255.0
client-identifier 0024.21b5.2ac0

sh ip dhcp binding:
10.0.0.194 0024.21b5.2ac0 Mar 23 2017 02:27 AM Automatic
10.0.0.198 0024.21b5.2ac0 Infinite Manual

Hi Brandan,

To statically assign a client with DHCP from an IOS device it should look like this:

ip dhcp pool STATIC
host 10.0.0.198 255.255.255.0
client-identifier 0100.2421.b52a.c0

The 01 in front of the MAC address identifies the client as Ethernet media.

Regards,
Sam
