if you count the syllables of CDP then you can remember that cdp timers are divisible by 3. for example, CDP has 3 syllables, the timers are 180 hold timer divided by 60 second update timer = 3. The same goes for LLDP, LLDP has 4 syllables in the acronym, and timers are 120 divided by 30 = 4! Easy way to remember hold & update timers for both protocols.

Hey Jeremy, it would be a big help if you could publish (for money or not) your text in the videos. (Obviously you're reading it, so there is very little work to do this.) The way many of us study is to review multiple times the same material. After the first video series viewing, it would be best if we could then read it-- to speed read instead of slowly taking it in through the video again. You are the best! Thank you Jeremy for your effort!
This is why I spend time taking notes. While OneNote is convenient, I mostly focus on hand written notes, because my eyes, hand and brain all participate in the process when I write, which helps me visualize the information exactly how I've written it myself when I close my eyes.

Enable the LLDP/CDP globally means, to enable the protocol on all interfaces of the device at once ???- right jeremy? or do we have to enable the protocol on each interface manually after applying command # cdp/lldp run
The global commands should also enable them on the interface level, so the interface commands are usually used in the 'no' form to disable the protocols on specific interfaces.

Why learn all the "show" commands by heart? You just need to know the logic of action. The router will tell you the rest after entering "show cdp?" It does not make sense

Hi Jeremy,
Hope you doing fine
You mentioned that CDP/LLDP are often not used.
What are main reasons an engineer/administrator would use them?
They'd use them to assist in mapping out the network. Also, if a Cisco IP phone is connected to the switch, CDP should be used to tell it information like what VLAN it is in.
very good, thanks Jeremy for the hard work.
Thank you for this video!
could we disable cdp globally and enable it on the interface ? thx for u r efforts sir and God bless u

hello!
if cdp is a layer 2 protocol than why "show cdp traffic" command shows "packets" and not "frames"?
thank you
The term 'packet' is often used as a general term, not just referring to the Layer 3 PDU
Thanks Jeremy for this great videos I would like to ask you if I have to read the CCNA book .. I have it PDF but I found it so big to this exam.. does this videos enough?
This course isn't finished, so currently it's not enough. I recommend using the book to fill in the missing areas.
Hi could you please give me the name of the book 📖
How to run wireshark on router or switch to capture such packets?
Within virtualized environments, it's possible with GNS3 - not with Packet Tracer
At 7:20, cdp is not enabled. so what does that mean? That the device is not a Cisco device? You said cdp is enabled by default on Cisco devices.
It means CDP was disabled.
Thank you for continuing to make these wonderfully helpful videos! When the multilayer switch didn't have capabilities listed with the lldp neighbors command... is it possible it's showing the enabled capabilities and not showing the system capabilities?
Hi, can you tell me the time in the video?
Enable the LLDP/CDP globally means, to enable the protocol on all interfaces of the device at once ???- right jeremy?
