How to enable or disable ports in a Cisco Catalyst 2960 using C #?

Question

I am a new graduate and just got my first job as a programmer in Hong Kong. As described above, I need to use C # to manage the ports on the Cisco switch.

I have been searching and studying for quite some time, so I have basic knowledge of SNMP and MIB. I can find some articles on how to manage a cisco switch, but none of them indicated how to enable or disable ports. At this point, it seems to me that I need to configure the switch to enable the SNMP service, then I have to send the SNMP Set packet to enable / disable a specific port. Is it correct?

Does anyone have experience and enjoy sharing with me? Please leave some suggestion. And if you have read some useful sites before, please kindly leave a URL here so that I can also see.

Thank you so much for your attention.

Answer 1

I know three methods (I like the first most):

Option 1:
A common way to approach something like this is to use automatic telnet (or automatic ssh) to send the appropriate commands. IOS is pretty standardized for the most part and works great in that direction.

The TCL Expect package is ideal for this kind of thing ... I assume there is a C # implementation.

This works best if you are already familiar with the IOS syntax.
