Ethernet

 

Introduction

 

Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the Physical Layer of the OSI networking model, through the means of network access at the Media Access Control Protocol (a sub-layer of Data Link Layer), and a common addressing format.


Configuration

 
Okapi(config)# interface FastEthernet 0

To assign an ip address to this interface
Okapi(config-if-eth)# ip address 172.16.155.10/16

Shutdown command is used to shut the interface. "no shutdown" is used to turn it on.
Okapi(config-if-eth)# no shut

To enable notifications in the event of change in the status of this interface
Okapi(config-if-eth)# link-detect
Okapi(config-if-eth)# bandwidth 100000
