Back 24

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

Front 25

What is a MAC Address?

Back 25

A 48 bit value for hexidecimal

Front 30

What are the problems with Cooper wire?

Back 30

It can break easily and many EMI sources

Front 31

What is the Troubleshooting Flow Chart for Switches?

Back 31

Is the cable good? check with .

#show interface

Check for noise - same

Verify duplex settings

Front 32

When reading interface statistics, what do you look for?

Back 32

Check for:

Excessive collisions

Excessive late collisions

Excessive Noise

Front 33

#1

How to diagnose Port problems?

Back 33

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

Front 34

#2

What are the next steps to troubleshooting Port problems ?

Back 34

Check the Speed settings just like you would the Duplex

Front 35

How can you view Speed and Duplex settings of a port?

Back 35

#show int f0/1

shows you port information
