You see, regardless of what CLI you are using, whether it’s Cisco or HP or some other vendor. Commenting your config so another administrator coming along can understand your thought process is always a helpful thing.
Don’t get me wrong. You can still figure things out without the comments, but if you take the time to do it, you can save an administrator valuable time when they are troubleshooting something in an emergency situation.
This can be just as simple as naming vlans and interfaces so people understand how traffic is flowing on your network when they are looking through the config. It can even help you if you haven’t read your own config for a very long period of time. It can help jog your memory.
So be a friendly administrator and comment those configs!
So what do you do? Well you can go and buy a usb to serial converter but they aren’t all created equally. It’s hard to find a reliable converter out there these days. I personally use a product from Gold-X (gxmu-1200) that works great.
I have used it for years and it works in Windows 7 and even works in VMware workstation. You can check it out here.
So the question you need to ask yourself, is does your firewall do everything you need? For example, there are some firewalls that will crush VoIP and refuse to pass the traffic properly even though they advertise they can. Or there will be some firewalls that will have a GUI or CLI but not implement it in the expected way making firewall administration a nightmare. Some block ports, but don’t do any advanced IPS or IDS.
So when you are buying a firewall, don’t just look at the security aspect of it. There is much more to a firewall than that. Also pay heed to the other features that will affect you everyday but that you just might not think about off the top of your head. Also just because a firewall has every feature under the sun, doesn’t make it a great idea to buy it. Sometimes it pays to seperate out features into different hardware appliances.
My point here is that everything is going to depend on your network needs. There isn’t one firewall that fits all. Do your due diligence and do that research before purchasing!
