Hi All

Good Day...

I have one query. i recently joined one company as a IT administrator profile. Company having 100+ branches with 1000 of Network devices.

They are going to provide me access (Telnet/SSH) for each device.

My question:

1. For giving access (Telnet/SSH) whether need to login each and every devices ?

2. How they will provide access (Telnet/SSH)any easy method ?

Regards,

Hello!

The company, which has thousands of Network devices is expected to have some monitoring and, maybe, provisioning system. I believe, local administrators may find any solution to provide you the access to network devices. But the exact solution depends on monitoring/provisioning system they use.

Cisco suggest to use the solution, called Cisco Prime Infrastructure. You can find more info about it here:

This solution is one of the best choises to monitor and control the large network, including wired and wireless devices. Among many other features, Cisco Prime Infrastructure gives you the ability of provisioning configuration automatically to many devices. So, this is the example, of how your task can be solved.

So, you asked about the easy way of configuring multiple devices. One of the easiest way is to launch putty from cmd with necessary options. So that you can make a script, which will launch putty, open ssh-connections to many devices and send the necessary commands to devices. For more information about putty options, please see:

But, as far as I know, you can face some problems with automatic launching of ssh sessions. If I'm not mistaking, you won't be able to pass the password for ssh connection.

Another way, you can use RANCID utility and it's component "clogin" to send commands to network devices:

RANCID is more suitable to run in Linux environment, but you can launch it on Windows machine, using emulator cygwin:
