Chapter 7 Configuring And Verifying Switch Interfaces

Question 1

How do your restore default duplex and/ speed settings on the IOS CLI interface

Answer 1

Issuing the no version of that command ie

No speed

No duplex

Question 2

What rules does IEEE define for auto negotiation for nodes to use as default when I negotiation fails

Answer 2

For speed use your slowest speed support often 10 Mbps

For duplex if your speed is 10 or 100, use half duplex. Otherwise useful duplex.

Question 3

1 Gbps speeds are always full Duplex true or false

Answer 3

True

Question 4

CRC

Answer 4

Cyclic redundancy check a term related to how the frame check sequence or FCS math detects an error.

Question 5

Runts

Answer 5

Frames that did not meet the minimum frame size requirements. (64 bytes) this can be caused by collisions

Question 6

Giants

Answer 6

Frames that exceed the maximum frame size requirement. (1518 bytes)

Question 7

Input errors

Answer 7

A total of many counters, including runts, giants, no buffer, crc, frame, overrun, and ignored counts.

Question 8

Packet output

Answer 8

Total number of packets forwarded out the interface

Question 9

Output errors

Answer 9

Total number of packets that the switch Port try to transmit, but for which some problem occurred.

Question 10

Late collisions

Answer 10

The subset of all collisions that happen after the 64th byte of the frame has been transmitted. (Usually points to a duplex mismatch)
