Cisco IOS software is installed in the manageable Cisco switches WS-C2960-24-S for better LAN management. It delivers network services and enabled networked applications. The Cisco IOS has a command line interface that helps users to execute the Cisco IOS commands.
Cisco Switch Commands
The Cisco switch IOS has different EXEC modes with distinctive prompts. These modes execute different Cisco switch commands. Each mode has a set of specific commands.
The fundamentals of the Cisco IOS User Interface are as follows:
• Uses a command line interface
• Operations vary on different series of switches
• Type or paste entries in the console command modes
• Enter key instructs device to parse and execute the commands
• Two primary EXEC modes are user mode and privileged mode
• Command modes have distinctive prompts
Cisco IOS Software Exec
There are two main EXEC modes for entering the Cisco switch WS-C2960S-48TS-L commands:
User Mode
• Limited switch examination
• Command prompt on the switch is switch
Privileged Mode
• Detailed switch examination
• Enables configuration and debugging
• Prerequisites for other configuration modes
• Command prompt on the router is switches#
Cisco Telnet Commands
There are two primary ways to access a Cisco manageable switch to use command lineinterface.
• Out of band Console connection
• Via Ethernet through Telnet
Telnet is a utility used for remotely logging into a device. To telnet a Cisco IOS switch from a computer, type the following command on the CMD computer’s terminal:
TelnetIP address of the switch
Just like:Telnet 192.168.0.253
