How to Starting a CISCO Switch

Basic Switch Configuration:

User-exec mode:
    Limited examination of a switch / router
             Prompt is <hostname> + “>”
    Switch>

Privilege-exec mode:
    Detailed examination of a switch / router
    Debugging / Administration / Prerequisite for other config modes                
    Prompts is <hostname> + “#”
    Switch#  

Global configuration mode:
    Configuration that affects the whole device
    Prerequisite for other config modes
    Prompt is <hostname> + “(config)#”

    Switch(config)#

Interface mode:
    Per interface configuration
    Prompt is <hostname> + ”(config-if)#”
    Switch(config-if)#

Ways to Manage a Cisco Switch:

Console need to end physical connection devices
Cabling the switch using the console, and then run a Terminal

Application on end devices.

Telnet switching and terminal connection needed
In the network.
Before it can be managed in this way, you must first configure a switch.

Aux port modem-exchanger must be connected to the modem and
Modems connected to telephone lines.
Before you might be, you must first configure a switch
Managed in this manner.

Set the device name:
Switch (config) #hostname Switch1-> sets a device identifier
Switch1(config) #

Set the password for the console:
Switch1 (config) # line con 0-> switch to the console management mode
Switch1 (config-line)->#password Cisco sets console password
Switch1 (config-line) will use the #login-> console password

Set the remote login password:
Switch1 (config) # line vty 0 4-> exchanger to Telnet control mode
Switch1 (config-line)->#password Cisco Telnet Password Setup
Switch1 (config-line) Telnet password is used->#login

Set the enable password:
Switch1 (config) #enable password Cisco-> to set enable passwords
Switch1-> (config) #enable secrets the enable password CCNA security

Encrypted password:
Switch1 (config) #service password encryption-> encryption of all passwords

Saving configurations:
Switch #copy <source> <destination>
-> Switch #copy started running to save the configuration
Or
Exchanger #write-> to save the configuration

Setting the IP address of a Switch:
Switch(config)#interface vlan 1
Switch(config-if)#ip address 10.10.10.1 255.255.255.0
Switch(config-if)#no shutdown
NOTE: the ip address assigned in “interface vlan 1” is the address that other devices must use to managed the switch.

Setting the Default Gateway of a Switch:
Switch(config)#ip default-gateway 10.10.10.254
NOTE: the default-gateway address is where the traffic, originated by the switch, will go when communicating to other network.

Configure security authentication:

Switch (config) # create a local account password Cisco-> #username teacher

Switch (config) # line con 0

Switch (config-line) means does not use the console #no login 0-> password

Switch (config-line) #login-> local means using a local account as the console password

Switch (config) # line vty 0 4

Switch (config-line) #no login-> means not using the Telnet password

Switch (config-line) #login-> local means using a local account as the Telnet password

Configuring banners:

Switch (config) #banner motd$ <Message> $-> configuration a message, will anyone connected to this device.

Switch (config) # #banner login $ <Message> $-> configuration via Telnet will be anyone from connecting to this device message.

Authentication configuration:

Switches running-> display the running configuration (new configuration) #show

Switch the display->#show boot startup configuration (save configuration)

Note: display the run/start command will let you see the FF:

Global configuration

Interface configuration

Routing/service configuration

Console and Telnet administration configuration

Common display commands:

Switch the display->#show version of the hardware and software information

-> #Show exchangers IP interface provides a brief summary of display interface

Exchanger #show interface < interface type >< display module/port >-> interface for more information.

Converter #show MAC-> Mac address-table display the contents of the table.

Determined to be directly connected CISCO devices:

#Show{more}-> the Cdp neighbors displayed directly connected Cisco devices

Note: * from the global configuration in the "no CDP run" to disable this feature for the entire switch, type

To disable this function, every interface, interface mode "no CDP enable" type
