These videos are so awesome! I wish I would have had these when I was getting started with networking. Getting down to the basics is so important and I learn something every time. Thank you!
These videos do not replace the course work of a good college or school on networking, but the goal is to encourage more learning and help fill in gaps of understand for some, and provide free training for many who do not have access to a good school or training. We hope our work stays awesome! Thanks for taking the time to comment and for watching and supporting the channel.
Thank you for touching a little bit on POe, I saw one Cisco that got wet but did not die and it sent more than 90 volts AC to its ports....changeling day....
I guess engineers do not expect the network closet and racked equipment to get water soaked. Most electrical equipment build in some type of short/overload protection. 90VAC would not be a good day for networking inputs!
Wow the other day I was thinking to myself "Mr V needs to do a video on switches because I was playing around the SFP port on a Cisco switch's doing a daisy chain You just answered my question about that console port! What about web based access to the firmware ? I opened up one of my Cisco switches, like you stated 3 big ASIC's with big heat sinks and a lot of glue logic , along with the switch mode power supply Thanks from fellow Floridian
It is affordable cable and supports up to 40Gbps which is where many switch uplink ports speeds are becoming more common. Here is the scoop on CAT8: Category 8 cabling has a greater throughput capability; it can support transmission of data up to 40Gbps over balanced twisted pair copper cabling. The solution is a shielded solution--there is no unshielded variant. Therefore, careful attention must be paid to shield terminations when installing the solution. All previous categories of balanced twisted pair copper cabling supported a Permanent Link Length of 90m (295’) and a channel of 100m (328’). Category 8 has a maximum Permanent Link Length of 24m (78’) and a maximum Channel length of 30m (100’) when supporting 25Gbps and 40Gbps speeds. Category 8 cabling can support data speeds of 10Gbps and lower at a full 100m (328’) Channel configuration. When field-testing Category 8 solutions, the installation is tested from 1MHz to 2000MHz, whereas Category 6A balanced twisted pair copper cabling is only field tested from 1MHz to 500MHz.
felt bad watching your great videos without subscription, so got yourself a new subscriber. keep 'em videos coming with dislikes at 0. all the best in 2021...
Thank you Lowell, as always great videos! Just one question: you say we're going to block applications like PUBG... but are you the best way is with a switch? Don't we need L7 support and app control (app signatures) to do that? Or at least L3/L4 firewalling and going the old way, with IPs and ports?
I was really just kidding, layer 2 is not a good option for PUBG but you can throttle some apps using QoS depending on the switch. Your point in the comment is correct. Thanks for listening and thinking!!!
no one can dislike your class sir because you give people hope to understand network.thank you so much
Thank you for the comment, not all my students like my classes trust me!
@@TechsavvyProductions they don't know that you are gift from God for them .keep up teaching students in need
Signor Vanderpool lei è il numero 1!
Mr Vanderpool you are the best!

thanks, i like the way u explain the systems work
Thank you for the comment and for watching!
Fantastic video. Thank you!!!
Thanks for watching!
Awesome video! Great educational supplement. Thank you for making understanding switches easy! Keep Em' Coming!
More to come!
This is nice. It helped my studies. ❤️💋
Glad it helped!
Great video like always
Glad you enjoyed

See how great minds think alike!?
Thanks for this video I learned a lot!
Glad it was helpful!
Great video, tremendous insights.

are cat 8 cables being used in enterprises at the moment ?

can i link for A Technical Introduction to Enterprise Network Switches and fiber optics Part 2?
Part 2 is what I am working on next.... TBA
Fantastic
