Understand the basic modes and commands of the switch (others such as routers are basically the same)
commonly used:
Switch> user mode enable (abbreviated as en to enter the privileged mode; exit to re-enter the switch command interface)
Switch# privileged mode (enable mode; exit to return to the privileged mode)
Switch (Config# Global configuration mode (conf t is entered by privileged mode)
Switch(config-if) #Port mode (interface port such as int fa0/1)
Other:
Switch(config-line)# (such as line vty 0 4 to enter)
Switch(config-vlan)# (For example, vlan 10 enters)
Other notes:
1. Commands can be abbreviated
interface-"int address-" add
enable- "en exit- "ex fastethernet-" fa, etc.
2. Some commands ignore the case of
Fastethernet fastethernet, etc.
3. Some spaces can be ignored such as The effect of fa0/1 and fa 0/1 are the same
. 4. The Tab key automatically completes the command "Command?" showing the available parameters of the command.
Familiar with the basic commands, you can deeply understand the efficiency and logic of the command line operation without losing the graphical interface operation
