1. Cisco Switching Basics
Use the link below, it will help today and in the future.

Everyone needs a console cable and a usb-to-console

Switch - 1
DHCP Pools:
Switch - 2
3750 Router
Switch - N
Port 1 = DHCP
If you don’t have it, you are not doomed. Let me know.

3. Command Line Interface
The Cisco CLI has 3 basic modes of operation:
User Exec Mode: Basic with show commands
Privileged Exec: More advanced commands;
Enter “enable” to get here
Global Configuration Mode: This is where you configure the device;
Enter “configure terminal” or “conf t” to get to here
Type ? when you are looking for a command or its options!

4. Command Line Interface - Shortcuts
Ctrl + A: Move cursor to beginning of the line
Ctrl + E: Move cursor to end of the line
Up Arrow: Display previous command
Down Arrow: Display next command (if you’ve pressed UP)
Tab: Complete the command

5. Cisco Startup and Running Configuration
Cisco has a startup-config that is read at boot. The Running-Config is running in memory. When you make changes on the switch, those changes are made to the running-config. Once you save the changes, they get saved into the startup-config.
Two ways to save:
write mem
copy running-config startup-config
If you are in config t / Global config mode, type `do` in front. `do write mem`

6. Basic Setup - Lab 1
Boss comes in and throws at you a beautiful nice cisco switch and says to configure it.
Unfortunately, it hit you in the head and you lost all knowledge of cisco networking.
Luckily you remember you had a list of things you like to set up before making switches go live. ←
hostname
telnet or ssh (preferred)
time (ntp)
snmp
logging
default-gateway
secret password
saving

7. Telnet or SSH Telnet SSH config t line vty 0 4 password cisco

8. What is a VLAN?
A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible.

What is a Trunk?

10. Setting up an Interface

11. Interface Vlans?

12. Native Vlans?
VLAN1 is on every switch by default. All the traffic is encapsulated passing over vlan 1 by default.
By setting the native vlan to use a ‘management vlan’ of 50, it is more secure.
Switch 1
Switch 2
Trunk (native vlan 50)
You have to set it on both switches on the trunk interface, if you do not you get a native vlan mismatch error and nothing will work.

13. Connectivity - Lab 2
Your boss comes in with a grin on his face. You regret looking at him, luckily he isn’t carrying anything but a piece of paper. That won’t cause any harm.
He talks about his boring fishing trip that seems to last until sunset. He then hands you this paper saying that the new switch you put in isn’t working yet and reminds you with this list of things to do. ←
You already knew what to do but didn’t get around to it. Now he is saying its top priority.
Setup each VLAN (2nd Slide)
Setup the Trunk port
Setup the Management IP Address
Assign a vlan to at least one port
Can you ping ?
Can you ping ?
Can you ping a neighbor's management ip?
