What is IP Addressing? |
Addresses used to identify a packet's source and destination host computers. |
|
What is IP Routing Protocol? |
A protocol that aids routers by dynamically learning about the IP Address group |

What is the IOS software? |
Allows the us to interact with the switch. To configure, monitor, and manage |
|
What is the CLI? |
allows you to use commands to configure devices using the IOS software |
|
What are the error messages used in the CLI when you make a mistake? |
Ambiguous |
|
What are ways to manage and save your Cisco IOS configurations? |
You can save them on an outside server using |
|
What are E-MACS (commands) ? |
EMAC commands are the shortcut commands Ctrl-A - Move to beginning Ctrl-e - move to the end Backspace Ctrl-Shift-6 (same time) - Abort ping or tracert Ctrl- U Erase a line Crtl- C Aborts the current command and exits config mode ctrl-z return to privileged Exec from Config mode |
|
How can you increase the amount of commands you see in the CLI? |
#set terminal history (number) |
|
How can you increase the output lines on the CLI? |
#terminal length 100 |
|
What is the pipe? |
Allows you to filter the output of a show command #show running | include hostname #show run | section f0/11 |
|
Understand the LEDs of the Switch |
Green, Red, and Amber 1: System LED 2: Remote Power Supply LED 3 - 6: Port Mode LEDs 7: Mode Button 8: Port Status |
|
How to configure management on a Switch? |
On the management VLAN (1) |
|
How can you find the basic hardware configuration of the Switch? |
#show version
|
|
How can you look up an interface? |
#show int fa0/1 |
|
What is Ethernet? |
It is a means of encoding information for transmission, most often for sharing files and other types of communication It is a layer 2 encapsulation protocol Providing consistency for network devices |
|
What is a MAC Address? |
A 48 bit value for hexidecimal |
|
What do Switches do in a Network? |
Using the Source and Destination Address it forwards packets over a frame on the network. It dynamically learns MAC addresses |
|
What is BUM Traffic? |
Broadcast Unknown unicast Multicast |
|
How can you view Duplex and Speed settings? |
#show int f0/1 |
|
How to Troubleshoot Switch issues? |
Use ping to see if devices is functional Use Telnet to gain access |
|
What are the problems with Cooper wire? |
It can break easily and many EMI sources |
|
What is the Troubleshooting Flow Chart for Switches? |
Is the cable good? check with .
#show interface Check for noise - same Verify duplex settings |
|
When reading interface statistics, what do you look for? |
Check for: Excessive collisions Excessive late collisions Excessive Noise |
|
#1 How to diagnose Port problems? |
Usually port problems are a result of Duplex or Speed mismatches. If auto negotiation fails to the wrong duplex (i.e. Half instead of full) If one is set to auto while the other is set full that can result to collisions |
|
#2 What are the next steps to troubleshooting Port problems ? |
Check the Speed settings just like you would the Duplex |
|
How can you view Speed and Duplex settings of a port? |
#show int f0/1
shows you port information |

NAS |
|
What does 100 Base T, "T" stand for? |
