In many instances I feel it will be disabled and would love some more clarification on how to address this.

Does this help anyone? .... QoS Traffic Shaping ... The benefits are: 1. Congestion Avoidance 2. Improved User Experience 3. Flexibility in Configuration ...controls flow using: 'RATE LIMITING' and 'SCHEDULING - like WFQ algorithm (weighted fair queue) + 'ASSIGNING PRIORITIES' to 'CLASSIFIED' traffic. ...uses 'BUFFER POLICIES', high priority = access to buffers, low priority = queue longer or dropped under heavy link loads. ...'POLICING' - Polices traffic entering + exiting queues, sets quantity limits + drops or marks a lower priority, preventing network congestion.

Hi Jeremy, first of all thank you for everything!! One question about PoE: for Ethernet and Fast Ethernet we are using pins 1,2,3 and 6 for data and 4,5,7 and 8 for powering up the device. How the SW handles with 1Gb+ when we need all 8 wires for data? Does it still use the same 4,5,7 and 8 wires for powering up? How can data be splited over electricity?? Thank uou and I don't know if it is a dump question..Thank you, sir!!! And, sorry for my english...

@JeremysITLab 2 жыл бұрын

You're correct about Ethernet and Fast Ethernet. For Gig ethernet and above, the same wires are used for data and electricity at the same time. Electricity and data transmissions use different frequencies, so they don't interfere with each other.

Great content, as usual! Question though, wouldn't the PC-to-IP_phone-to-switch cable setup create a bottleneck? I don't think it's common for IP phone ports to support equal or better speeds than (desktop) PCs?

@myleslivingston6568 Ай бұрын

most end users aren't fully saturating the their network connections thus no concerns for a bottleneck. If you have video editors, engineers or other users that are constantly relying on network storage for large files you would want to wire them in into the switch directly if the infrastructure supports the speed they need.
