Cisco Cisco 2000 Series Wireless LAN Controller Troubleshooting Guide

Configuring DHCP Server

In this document's example, Cisco IOS router is used as the DHCP server. These IP addresses are used:

10.77.244.196 − TFTP Server

•

10.77.244.220 − DHCP Server

•

It is assumed that the IOS router is already configured and active on the network. Here, only the DHCP
configuration required for this document is shown:

!−−− (Exclude the addresses that are already assigned in the Subnet)

ip dhcp pool pool1

Sample Output of AutoInstall Implementation on WLC

This is an example of an AutoInstall process from start to finish:

(Cisco Controller) >reset system

System will now restart!

Would you like to terminate autoinstall? [yes]:

AUTO−INSTALL: starting now...

rc = 0

AUTO−INSTALL: interface 'service−port' − setting DHCP file ==> 'WLC−4400.cfg'

AUTO−INSTALL: interface 'service−port' − setting DHCP TFTP Server IP ==> 10.77.244.196

AUTO−INSTALL: interface 'service−port' − setting DHCP siaddr ==> 10.77.244.220
