Using CDP to map a network

I am trying to use Putty to SSH into these items for a school project. I am currently unsure of what I am doing wrong but I keep getting errors that say time out or refused. I am just trying to get a network mapped out on packet tracer. This is what I have started.

Using Putty or another software of your choice, complete the following:

1.  SSH to the CIS 228 Edge Router - 50.252.122.235 (External IP)
2.  SSH into the CIS 228 Core Switch - 172.16.254.254 (Internal IP)
  * If you do not have credentials, please Canvas message me and I will set those up.  You can also come to the classroom/lab and setup those yourself.

 

3.  SSH into 172.16.254.253 - Unknown Network

 

This unknown network has a combination of Cisco 2960-X series switches and Cisco 1921 routers.

You will want to SSH to all that you discover.

 

4.  Commands to investigate:

show cdp
show cdp neighbors detail
show cdp entry *

debug cdp events

Map out the network that you now have access too. 

Build a sampling of it in Cisco Packet Tracer.  It does not have to work, just show the physical connections and the devices.

Upload it here when completed.

When I looked at the Switch and the Router configuration ssh is not enabled on those devices.
