Hello Lamin,

I've never done this, however from the message above I think the client switch has taken the tar file for the config file.

the example in your reference is different:

Switch# config terminal

Switch(config)# ip dhcp pool pool1

Switch(dhcp-config)# network 10.10.10.0 255.255.255.0

Switch(dhcp-config)# bootfile config-boot.text

Switch(dhcp-config)# default-router 10.10.10.1

Switch(dhcp-config)# option 150 10.10.10.1

Switch(dhcp-config)# option 125 hex

0000.0009.0a05.08661.7574.6f69.6e73.7461.6c6c.5f64.686370

Switch(dhcp-config)# exit

So first the client switch has to load a config file and later it will download the image.

Note:

Before following the steps in this table, you must create a text file (for example, autoinstall_dhcp) that will be uploaded to the switch. In the text file, put the name of the image that you want to download (for example, c37502970-ipservices-mz.122-44.3.SE.tar). This image must be a tar and not a bin file.

then the client switch can do:

This example uses a Layer 3 SVI interface on VLAN 99 to enable DHCP-based autoconfiguration with a saved configuration:

Switch# configure terminal

Switch(conf)# boot host dhcp

Switch(conf)# boot host retry timeout 300

Switch(conf)# banner config-save ^C Caution - Saving Configuration File to NVRAM May Cause

You to Nolonger Automatically Download Configuration Files at Reboot^C

Switch(config)# vlan 99

Switch(config-vlan)# interface vlan 99

Switch(config-if)# no shutdown

Switch(config-if)# end

Hope to help
