CISCO PT Simulation Experiment (2) port configuration and management for switches

Experimental Purpose : Master the basic configuration and management of the switch, and understand the basic commands of the switch configuration.

Experimental background : A company has a new batch of two-layer switch, before formally put into use to initialize the configuration and management, in order to maintain later.

Technical Principle :

• There are two basic ways to manage switches: in-band management and out-of-band management.

  • by The switch's console port management switch is out-of-band management, which does not occupy the network port of the switch, the first configuration switch must take advantage of the console port to configure.

  • through Telnet , dialing, etc. ( TCP/IP protocol) belongs to in-band management.

• The command line operation mode of the switch mainly includes:

  • User Mode switch>

  • Privileged Mode switch#

  • Global configuration Mode Switch (config) #

  • Port Mode Switch (config-if) #

• When configuring the switch, pay attention to the single-duplex mode matching of the switch port, if the link end is set to full duplex, the other end is auto-negotiation, it will cause poor response and high error rate, packet loss is very serious. It is generally necessary to ensure that both ends are set to the same pattern.

• line When you set a password in configuration mode, only passwod Span style= "FONT-SIZE:10.5PT;" > command, no Secret command, default is clear text display, need to enable password encryption ( global ) When enabled, all passwords within the configuration will be displayed in ciphertext form.

Laboratory Equipment : switch_2960 1 units, PC 1, configuration line, straight line.

Experimental steps:

Configuring switch port parameters (Speed,duplex)

Check port information (show interface)

Select a port (interface type Mod/port)

Type represents port types, usually Ethernet, FastEthernet, gigabitethernet

MoD indicates the module where the port is located, and port indicates the number in the module

Select multiple ports (interface range type Mod/startport-endport)

Set port communication speed (speeds [10/100/auto])

Set port single-duplex mode (duplex [Half/full/auto])

Enter route configuration mode (line [console/vty] number)

Console indicates that the device is connected via a serial cable (control/configuration port) for local login

Vty means connecting to a device (virtual port) via Telnet, etc. for remote login

Number indicates the line numbering, 0-15 in 0,vty mode in console mode

Set the login password for the console or vty line

To open the Login function for the console or vty line

Enable the Global Password encryption feature (service password-encryption)
