Cisco IOS upgrade in depth

whizkidraj

Level 1

Hello all,

 

Can anyone help me with IOS upgrade for Cisco switch and router.

1st case:- Upgrade IOS on switch.

What I should always have:-

I will have a laptop with the free tftp software on it.

I should have a straight-through ethernet cable, and free Putty software.

 

Scenario:- I reach the site and I have to upgrade a Cisco switch and a Cisco router (any model).

Let's upgrade the switch first.

I will insert one end of straight-through ethernet cable to laptop and 2nd end to switch.

So can anyone help me here with some image demonstrations to help me know which port of the switch I should connect the 2nd end of the ethernet cable to.

I am asking which port because if the switch is L2, then we would have to assign ip to vlan1, and this concept is related to SVI, right, and in SVI concept we insert the ethernet cable to the management port of the switch, right.

Please just guide me through further steps. I am not asking about the copy commands i.e backup or restore or upgrade commands, I am just asking about in-depth guide on how to connect the switch to my laptop so that I can transfer the files from tftp to switch and vice-versa.

If there's any video guide for this then that will be best, but I have searched the whole internet and no one provides such information from scratch or directly just do the commands on packet-tracer.

 

Also do post the same image/video tutorial for connecting laptop to router for ios upgrade (if you know any link).

Things like, how to know which interface I have connected the 2nd end of the ethernet cable to (for switch and router), and how to connect laptop to switch, and laptop to router.

Please just help me with that. Would really appreciate sincere help coz when I ask some people the same questions, they make jokes or just ignore that I am asking such a basic question, instead of helping me just once.
