Using a Cisco Router as a TFTP Server

I got a security license key from Cisco that I need to TFTP and install on a remote router (for work). The only problem was the distance and I was also quite lazy to travel since it was on a Friday. I've found a convenient way of transferring files between two routers by configuring one of them to act as a TFTP server. FTP was supported on older IOS train but was removed due to security exploits.

First, I transferred the license key file from my PC to a local router. Since we've got public IP address assigned to the WAN interface, it's easy to transfer the file over the Internet.

We use the tftp-server command to function as a TFTP server and specify the location and filename that can be downloaded.

2811(config)#tftp-server flash:FGL1748115S_201404032246233900.lic


The remote Cisco 2911 router doesn't have the permanent security license installed yet. We verify this using the show version command.

My Cisco 2511 Router IOS Upgrade

I bought a really cheap Cisco 2511 router to function as my terminal server. This legacy router (even the 2511-RJ model) is sold at a premium price on Ebay since it can be used as a terminal server/access server in both lab and production environment.

I also bought an AUI Ethernet adapter which is needed to connect the 2511 with an RJ45 cable to my PC when upgrading the IOS via TFTP (the router was sold operating in ROMmon mode).

                                                          

So I gave the router an IP address and performed the IOS upgrade. I plan to use AUI adapter in order for the 2511 to join my network lab later on. This would allow me to access my rack remotely using my iPad or laptop via wireless inside my room (rack is sitting at my living room).
