Cannot Connect to TFTP Server Through Serial Console Cable During Basic Config

[masshakar]

I am very new to routing and have zero background in it.

My situation is that I have a Cisco 2811 router and wanted for my serial console cable to connect to the TFTP server and auto-configure.  All I have connected is the RJ45 (2811/DTE end) to USB connector (laptop with PuTTY open /DCE end), and the router's power cord into the power outlet.

In privilege mode, I type in reload, and proceed with basic configuration:

When I can connect to PuTTY, I do have serial communication, but I am not getting any serial interface to auto-configure with SLARP, and my IP-Address is unassigned:

Interface                     IP-Address     OK? Method     Status      Protocol
FastEthernet0/0         unassigned      NO   unset        up           down
FastEthernet0/1         unassigned      NO   unset        up           down
Serial0/0/0                unassigned      NO   unset        down       down
Serial0/1/0                unassigned      NO   unset        down       down

What am I missing here?  I tried to go back to factory settings through "write erase", but am getting the same results.  And I had tried to follow this, but giving serial interface an ip address and helper ip address again resulted in a down serial 0/0/0 with an unassigned IP address.

Hi @masshakar 

The console cable is only for configuring the device, but not for network traffic.
The serial indicated in the guide is a DCE / DTE
