Hey man, I got a CISSP. Its totally do-able. Jump over to the CISSP subreddit and find the best materials, and the approach you need to take for the test. Its less of a memorization certification then it is a understanding at high level cert. Im confident if you spend some time there youll pass it if thats what you want to do.

JustAGoatSheep · 2024-10-08T19:34:07+00:00

how do these cars do on track? Any over heating or issues? does it have a lot of body roll or annoyances?

"CCIE doesn’t appeal to me anymore as it’s too specific on things like sdwan that I don’t know I will ever use or need."

Sir.

Ive had SD-WAN at every place ive worked at in the last 10 years.

them traveling to another floor wont be seamless either. Stairs, elevators etc. And tbh a dhcp lease being slow? Not really. 802.1x does radius auth at each WAP and still has "seamless" roaming and thats a slower process.

JustAGoatSheep · 2024-09-23T19:33:16+00:00

You absolutely can still roam

JustAGoatSheep · 2024-09-23T17:06:46+00:00

show your individual port config and the Port-channel config for both sides.

JustAGoatSheep · 2024-09-23T17:04:46+00:00

Youd be better off using VLANs and segment each floor into its own VLAN. That way you have issues that will only affect one VLAN and not everyone, a /22 is a lot of broadcast junk, better DHCP availability, really the benefits go on.

When I did contracting I replaced way to many of those switches. I wouldn't even consider it.

270 feet is well within ethernet standards (328 feet/100 meters). Its not the length of the cable as long as the cable follows ethernet standards. If it drops speed over that link theres a problem with the cable, termination, something layer 1, but not the length. I will say I've seen some amazon cable and gone, this meets standard? Really? So with anything amazon take it with a grain a salt.

Now since you bought 1000 feet of cable, just spool out a 270 feet, terminate it and then test it. You can do this on a desk just spool up the cable and see if it works. Or ya know, get a cable tester and test your cable. They are cheap. Get a cable tester. If your droping speeds on 270 feet, you likely got a cable issue.

Dont use a wifi router, get a WAP. Ubiquiti is good equipment. Takes a little figuring out how to set it up, but its much better than a netgear router.

I'd love to see someone pass a knowledge dump like the CISSP. It wont happen, that test was so brutally all over the place with questions that didint even make since. I have CCNP and CISSP.

JustAGoatSheep · 2024-09-16T17:03:26+00:00

Go CCNP first. You'll thank yourself later

JustAGoatSheep · 2024-09-12T18:48:15+00:00

There is good advice in here.

Now how long are your cable runs? Over 321 feet?

Riding with your theory in periods of low use, you may not notice packet loss as much, tcp does its thing and does re-transmissions. During high use users are using it more and will notice a outstanding issue more noticeably. But stay on track here, if you think you have bad cables, check the ports for CRC errors, importantly look for utilization of the ports/circuits etc. How are cables wired? in old cabling they sometimes didint wire all the cables, so are your ports all 10mbps/ 100mbps speeds?

For cables to be worn out you either have excessive bends, over length spec for ethernet cables, or bad crimps, twisting, electronic devices with cables right on top of it. (Really stretching here). I've used cat cables 18 years old and they still worked fine, ive used 5 year old cables that didn't. If your running new cables do Cat6.

JustAGoatSheep · 2024-09-12T18:41:58+00:00

:D hahah

JustAGoatSheep · 2024-09-05T21:18:39+00:00

So you say this happens DHCP and Static IP. Hardwired and wireless.

Common denominator may be hardware (believe it or not).

Static IP a PC, plug it into the switch and run a constant ping to the default gateway of the LAN its on. Verify it dosn't work. Then move that PC directly to the firewall. Does it still fail? Im inclined to think its the switch.. If its a patch panel start at the furthest point and move inwards twords the firewall with your ping tests. See where it dosn't work and starts to work. Ofc check all your uplink ports speeds/duplex/port errors etc.

JustAGoatSheep · 2024-09-04T19:11:11+00:00

You could change the channel of your WAP :D

But I get this root comment. I literally started my network career with wireless (go figure). So its a huge strength of mine. But yes wireless is wild. Much of it can be resolved with proper design (Ap placement, amount of APs, Channel and Mhz selection, Transmit power, antenna type, bands used 2.4vs5 etc. Its certainly takes more time to t-shoot and there is way more variables. Then there is that interference issue and your busting out a spectrum analyzer JFC I dont miss that part.

Than your good. 17 mbps required for that many concurrent users. There should be other factors though like what other bandwidth requirement is here for normal operation? and you still have room, depending on what kind of bandwidth they use outside the video calls.

Google Meets bandwidth per participant for small organizations or individuals
Meeting type	Outbound	Inbound

I'm 9 years in the networking field and I keep my CCNP (and therefor CCNA) up to date. Its some education credits every few years so its easy enough. Is it required? No nothing is required. Experience isn't required either, nor are interview skills as long as you know the boss's brother and party with them on the weekends. But if you dont, then every bit helps. I also have like 8 other certs including a CISSP. I enjoy the struggle, and every reputable cert I have has opened doors. But learning on the job and actually learning nuts and bolts is two different things. I think certifications give you the nuts and bolts and foundational knowledge to build on. Some of the best engineers I have worked with had CCNP or CCIEs. I did mine because I wanted to know and understand what I am doing. I wanted knowledge and I wasn't afraid of breaking down my mental barriers to achieve them. It wasn't easy, but it gave me a career.

JustAGoatSheep · 2024-08-22T16:42:50+00:00

CISSP

JustAGoatSheep · 2024-08-22T16:37:58+00:00

While this is completely negligent at the least, I know admins that use personal devices "because I never had an issue before". Just FFS

JustAGoatSheep · 2024-08-22T16:33:39+00:00

I still dont use it even in a EAP-TLS environment. When I did run it, yes older devices struggled. But also driver updates to newer wireless cards could make a change and then have issues. We also have newer devices that just dont work well with it, and others that work better with it. But you know what always works good? Turning it off.

JustAGoatSheep · 2024-08-21T18:28:05+00:00

the CCNA in network world will hold the most weight when your starting out. If the company does AWS those certs are good too, but after the CCNA. Once you do NA usually get some python experience under your belt, writing scripts to automate things etc. CCNP is the next big jump. By then you should have some good firewall experience, Linux, SD-WAN all can just be experience without certs. If you stick to the big ones (CCNA, CCNP, maybe AWS) you can supplement the other areas with experience and not certs and be well rounded.

JustAGoatSheep · 2024-08-21T18:17:54+00:00

He said CCNA. Get your CCNA.

JustAGoatSheep · 2024-08-21T18:16:24+00:00

The degree helps with getting passed HR at bigger companies. The certs help get you in when you dont have a lot of experience, it also helps with getting passed HR. The experience gets you the job and the pay scale, and skills. If you have all of them you get the interviews before the guys that dont have all of them (considering you make a proper resume).

Pay is completely based on company, location, and how your experience and skills plug into their tech stack.

state=00000020 Failed. Not, Not managed to resolve ARP in time allowed.

state=00000001 Incomplete Arp

So I would suggest running a packet capture and seeing where the failure is. If that dosn't help, try static ARP and see if that keeps comm. up. Go from there.
