Time to start on number 2, for the night

Anyway, lets do some questions.

First of all, what the hell is switch stacking

The Switch Stacking is a feature that allows us to configure multiple Cisco switches in a way that they appear as a single switch and act cooperatively. For example, if you have five individual Cisco switches, the Switch Stacking allows you to use all of them as a single large switch.

After reading about this I think the answer to the question, again, best explains the concepts they are after here. However, this is helpful

Key points
  • You can add up to nine individual switches in a stack.
  • Only the switch which has a special stacking module can join the stack.
  • To connect stacking modules, a special stacking cable is used.
  • All member switches of the stack select a master switch.
  • The Master switch provides all switching related features and functions such as CDP, VTP, VLAN, STP, etc.
  • Besides the master switch, no other switch is not authorized to run any switching related service.
  • MAC address table is maintained only on the master switch and it references all ports on all physical switches.
  • Each stack has only a single IP address and that is assigned to the master switch.
  • Each stack has only one configuration file and it is managed on the master switch.
  • When a new switch is added to the stack, the master switch automatically configures it.

That’s all for this tutorial. If you like this tutorial, please don’t forget to share it from your favorite social platform.

So all switches are connected but the master switch has the config.

This is what I find confusing in the question it says serial0 but the answer says serial 0. I guess we can assume the answer is right. Regardless, as is almost always the case, there is probably still more to learn but lets get into it deeper at a later date without chasing too many rabbits. I still have nightmares about that from the 2012 MCSA

This is really straight forward in the answer but im not sure I understand what clock rate is or what purpose it serves.

lol so basically nothing but the important note is that a modem ie the network provider, provides the clock rate.

also probably from an ISP?

Not really much to look up here but its good to go over this again.

Thats all for tonight!
