All right, this is not the weather. We're not trying to control storms. Okay, but we are trying to control the broadcast the multicast and unicast per port using the storm control command. Okay, all the controllers configured on a per interface basis to monitor traffic that's arriving or being received in the interface. The idea is to take the action on the frames as they enter the switch and arrive to an internal switching bugs before they're floated to multiple switch ports. So it's gonna be looking at each and every frame that comes in multicast frame broadcast frames, unicast frames, or whatever frame that comes in.
Before it gets flooded out. It's gonna say Okay, wait a minute, how big are you because you're gonna put constraints on this. We're gonna look at in a second woman at the front configuration. And then you're gonna put, you know, constraints, thresholds, whatever you want to call it levels. All right? To say, okay, past this point note.
And you can use SNMP or traps, whatever, to go ahead and show them a port to go ahead and take care of that. Now you can configure thresholds, which I just said before they want to broadcast multicast or unknown unicast traffic and take an action when it exceeds. And here it is. Again, I'm gonna repeat myself. repeat myself. Made sure your iOS on your switch has that feature for storm control.
So I can see it now. Last, my simulator doesn't use storm control. Well, probably not. Okay. Probably not. They were using the packet tracer.
Yeah, it does. The latest and greatest does it. Okay. Ah, if you're using an s3 Miss, you have the right iOS has that feature. Whatever simulator or if you have the real equipment, you don't matter, make sure you have the iOS that's gonna support that, because that's what I find funny. People are saying, well, we're using a simulator that's not real incident is the same thing.
So is viral or the latest similar from Cisco, not real. Okay? If you're using a real iOS or a programmed iOS, you're still typing in the commands. So just make sure all right, they can type that. Alright, so you go on the interface bremer's a per interfaces, you can do a range Mojave storm control broadcast this symbol you don't need to put it this way, you know that i number is the percent. So in the broadcast level goes above 50%.
There's something going on the action will you can put it you know, Configure SNMP and what have you for source control. So storm control multicast level packets per second. That's what the PPS means. Okay, packets per second 50 K, what's 50 k 50 kilobits. Now that's 50 kilometers, because the kilobits, okay. So if it goes above 50 kilobits, we have a problem.
And lastly, song control unicast level, this is a percentage, we want to in between 20 to 10%. That goes off 20 issues is within 10. Okay, so we want to within that range, so range, okay, is a percent is the percent, not a big configuration, then you can specify an action to be taken. That's what I talked about the threshold is exceeded using SNMP trap as our first form conditions. Here's it is in the interface where it's the range or one more whatever it is storm control action, you can either shut down or do whatever trap and from zero to 70 into whatever trap you want to go ahead and do that. They'll give you the alert but again, Again, all these things, security monitoring, and there's more margin than anything else.
Okay, this could be done with third party applications. Okay, can you do it on the Cisco routers and switches? Sure you can. Alright, certification, you have to learn what this is. I you know, all right. This is just looking at all these different frames coming in and saying, Hey, wait a minute, we're going above a certain level.
No, no, no, no, we can't allow that. We have this action that says that it goes beyond that and shut it down or whatever trap message you want to put on there. Or just letting you know, that's it. This is a configuration from storm control. But, again, the problem that you're going to run into when you start practicing this stuff, does your iOS have no future? That's it Your biggest concern.
All right, if you're going to practice at night, remember, remember the command. That's all just remember the command and you'll be fine. Alright, doubt it, you're going to get a actual lab scenario for you to configure storm control. I can tell you that in your CCNA security, you good possibility that you'll probably do switch port security that we just talked about. Not too long ago. All right, but other than that, no doubt that but that's what this is what store controllers All right.
That's it. No see in the next
