@Adam-Tyler,

That's really the difference in configuration. this is important though. You cannot use someone else's AS number on the internet. That's bad.

@Shannon-Wright said in Trunks and VLANS:

If I create a trunk between two switrches, do the VLANS on each switch have to match in order to carry the traffic between the two switches?

They do not have to match EXACTLY.....for instance I have 10 VLANs on one switch and 8 VLANs on another switch. If you have multiple devices in the same vlan but connected to different switches, those VLANs must be configured on both switches.

@Ronnie-Wong thanku sir problem solved

@Shannon-Wright,

I'm not sure what. you can run on the SG-300. But if it take the command: show mac address-table this should shows you the table then you can see if there are duplicate MAC addresses in the table.

You may want to just plug your encoder directly to your laptop...and see it shows up on your laptop's arp cache then compare that against output on the switch's mac address table.

@Ronnie-Wong thanku ronnie sir for the reply

@Roscoe-Govan ,

On the first question, please submit this question through the chat bubble on our site. Our member services team can help you with that. It may come down to a glitch. But they can check for you and let you know what the issue and hopefully resolve quickly.

The Cisco ENCOR 350-401 exam is a single exam, 102 questions. Covers a lot of stuff but we do have a show with Anthony Sequeira of Cisco fame to lead us through it.

Thank You so much I was looking to do this myself and stumbled across it here!

SD-WAN is part of Fortinet and Cisco firewalls. I have a Fortinet 60E firewall at home with SD-WAN. You configure SD-WAN by adding in both WAN ports. I have two ISPs. After that, you add the destination to the internet as the SD-WAN. You don't do much more with it. QoS and packet rules just point to SD-WAN instead of an interface. You can to policy based routing to individual interfaces and setup QoS to give priority. Usually not really needed. What did you want to know about SD-WAN?

I personally like to use DHCP scope on a specific "management" vlan and then after the AP boots and I identify it, I can just create a reservation in DHCP. DHCP also allows you to apply option codes if needed, such as CAPWAP server.

Thank you Ronnie.

@FLM,

They will help...but on the CCT, it's weird. This has to do more with being a field technician in setting up the routers and switches and handling them than with their functionality and operation.

So always, having a more advanced concept, like what you have in CCENT, is helpful. But this exam covers other area which are not covered in CCENT. I try to emphasize those during our show.

@Jerryl-Nicolas,

First you want to do a search for Cisco Exam 200-301. Find the objectives and download them. Print them out.

Mark each topic from 1 to 5 - 1=not familiar, 5=I could discuss this topic intelligently and confidently.

Create a study plan for 1 1/2 hrs per day. Divide that into 3 sections: Two, 15 minutes for topics you've marked as 5 and 1 hr topic you've marked with 1-4. You will take 15 minutes 1st, review a 5 topic. 1hr to study a 1-4 topic, and end with 15 minutes to review another 5 topic. Do this daily, do not skip a day.

You can study using ITProTV content,web searches,blogs and books (which you will have to purchase. You can post questions here in the forum to get help from myself or other ITProTV members.

If you're rusty, I recommend you find in the course section, Legacy, look for CCENT (2018). This is a full 38 hr review of all networking fundamental before you take the CCNA. If you look at the topics and feel good, then head over to Cisco and begin studying with CCNA 200-301 series.

The study progress depends on what you would do as a individual. I gave you the way I would setup a study plan above. this way, each study session always begins and ends with a "win". Gives you. plenty of time to study harder topics. There is no magical path formula through the course. I recorded them in the order I thought was a correct way to tackle the content, assuming you had the prerequisite knowledge.

Let me know if you have any additional questions.

Are there any plans? I love the ITPro TV courses and overall it can help to expand the offering of the platform to customers. Also it will make ITPro TV more marketable.

Thank you for the information will save the configuretion into a text file

@Nathaniel-Sears,

The diagrams that I created in the CCNA show was made in SimpleDiagrams4. You can find it at www.simplediagrams.com.

We've been using it since the beginning of ITProTV 7+ years ago and still use it today. I like it but having said that. I'm not going to say it's easy to use. But they have a 7 day trial you can download and try.

@Chris-IT said in Security related question of the underlay and overlay networks:

Hi there, I know I'm getting ahead of myself here but got some shower questions to ask.

My apologies, this one slipped past me...

As mentioned in the title, I was wondering if about the security aspect of the SDN networks.

The first question:
If there's Cisco TrustSec operates at the policy plane/security implementation and the existed underlay networks having their own security feature. Would they have any conflict of security between them?

No. The underlay and overlay security should be complementary. Now having said that, If you block it at the underlay, you're blocking connectivity generally...but usually, you implement good infrastructure security at the underlay, then security policy on the overlay.

The second question:
Can we implement security features in the overlay networks only, and connectivity only in the underlay network, will that work? If it will, can the attacker utilize this to attack the network?

Like all things, you can do what you choose but generally, if you're using SDN, the underlay is abstracted away. Attackers, will attack what they know to be there. So like all good things, you implement security based on the CIA triad as best as you can.

Thank you

@Abraham-Oz,

We don't currently have it on our roadmap. Having said that, you can make a course request through the chat bubble on our site. This will officially log your request to be counted with other requests. If there are enough requests, we can put it on the schedule.

@Abdullah-Alrawi,

The labs are conceptual labs on paper to get you familiar with the topics mentioned. For the CCNA exam, there will be no configuration that you will have to do with the cisco equipment listed in the exercises. The exercises beginning with 8 are all theoretical exercises.

@Abraham-Oz,

If I remember correctly, those are the episodes that I created the labs for. The rest of them were simple 2 router configurations. So I don't believe we included any additional CML yaml files for them.

@Abraham-Oz,

So, my opinion here only. I believe the writers took elements of their previous work in whole and got them edited together to try and make a compendium volume which is what we see in the OSGs. Though the material is ok, yes editing was not their strong suit. Also the editing that was done was done, I believe for length rather than anything else.

The guy behind the network lessons is a phenom. I have nothing but humble desire to be more like him. He writes well and if there is errata, he changes it quickly and is constantly developing very good content on a multitude of topics.
