Well, Mike, everyone, we made it through the section. not such a big deal. You seen this before. I hope some of you have seen this before. All right. Again, I said if your review, what do you need a manager and an agent, know about the management information base, make sure that is updated once you get in a real world scenario.
Once you get it, if you need to go back to Cisco, say, Hey, where are you got it from? Hey, I need the latest and greatest MIB. Because that's where those old IDs those identifiers with object identifiers are up to date so you can see wherever you need to see. Remember about the parts UDP ports 161 162. This is the normal port that they hear information on the agents. This is a port that the agent sent on, solicited messages to the manager.
All right. We thought about the different commands that can used and then as well. And then the comparison or the SMP were SNMP versions 123 most popular. Alright, and version three, one, completely unsecure. It uses community string 32 bit version to see 64 bit completely unsecure. A body also has to get bulk, you can use that as well, as well as the informed request command that he has.
Alright, but again, it has a read only or rewrite type of community string here, in essence here and SNMP version three, that's where you have authentication, username authentication, you're placed into groups levels, so it's completely different. Okay, so this is something you want to do you have the encryption, all right, that's also there. Again, MT five ds 3ds. Sha, you have all that stuff. You can love to 256 bit encryption using as So, definitely SNMP version three is what you want to use. And that's what you really just need to know.
All right, for certification, once you get out there, I'm telling you, I'm telling you start looking into third party out once you get your cert, start looking into third party applications, you will those causes all about you will then look at see how they're configured more or less. So when you do go to interviews, you know what it is that you want? You know, when they ask you a question, Well, how do you use the this particular console? Well, I heard something. I've heard that you do this, this, this and this. Okay, you guys know something about it?
That's all. That's all it is. It asks you what SNMP is. Yeah. Is it gathers information of all your devices. There it is, no matter if it's a Linux box, Mac, Windows, whatever it is, is when again, all right.
And then you saw the different configurations for the different versions of one two, C and three. All right, that's that don't freak see on the next
