Cisco (Cisco) switches? C3750-e? 1. Configure line Connection and login

"Introduction" is a Cisco with Stackwise Plus? Catalyst? The 3750-E series switches are an enterprise-class, stand-alone, stackable wiring switch family that supports the deployment of secure converged applications and maximizes investment protection based on the development of network and application requirements. By combining A/V and power over Ethernet (PoE) configuration with a Gigabit Ethernet uplink, the Cisco Catalyst 3750-E can support applications such as IP voice, wireless, and video, increasing employee productivity.

Key Features of the Cisco Catalyst 3750-E series Switches

• Cisco twingig Converter module, porting uplinks from Gigabit Ethernet to Gigabit Ethernet
• Poe configuration with 15.4W Poe for all 48 ports
• Stackwise Plus provides ease-of-use and resiliency with throughput rates up to up to Gbps
• Modular power supply with externally available backup power
• Provides IPV6 routing, multicast routing, and access control lists (ACLs) in hardware
• Out-of-band Ethernet management port, and RS-232 console port

The following table lists the configuration of the switch:

features	Description
Cisco Catalyst 3750E-24TD	24 Ethernet/WAN ports and 2 X2 Gigabit Ethernet uplinks
Cisco Catalyst 3750E-24PD	24 Ethernet/WAN ports with poe,2 X2 Gigabit Ethernet Uplinks
Cisco Catalyst 3750E-48TD	48 Ethernet/WAN ports and 2 X2 Gigabit Ethernet uplinks
Cisco Catalyst 3750E-48PD	48 Ethernet/WAN ports with poe,2 X2 Gigabit Ethernet Uplinks
Cisco Catalyst 3750e-48pd-f	48 Ethernet/LAN ports, each supporting 15.4W poe,2 X2 Gigabit Ethernet Uplinks

3750-E Switch Configuration cable Connection

Here we are configuring the object with the Cisco Catalyst 3750e-24td.

① turn the switch on and wait a few minutes before the left led on the front panel flashes from the flashing to the long light. When the Syst, MASTR, stat Three lights are solid, the firewall is working properly.

② front panel to the right is a network cable access interface, inserted into the network cable indicator light, when the preparation work when the amber light, normal work after the green light.

The RJ45 port of the ③ configuration line is plugged into the console port on the back of the switch.

④ since most of the current notebooks are no longer configured with serial ports, so the configuration line can not be directly connected to the use of notebooks, you need to convert the serial port into a USB port.

⑤ connect the DB9 male header of the configuration line to the DB9 female of the USB conversion cable.

The ⑥USB switch line USB header is inserted into the notebook computer. The connection is complete even.

"Hint" USB Conversion cable needs to be installed after the driver can be used, at the following address can be downloaded to the driver (including WIN10 driver), the specific installation steps are no longer detailed.

emulation Terminal Connection

After Win7, the system no longer comes with the emulation terminal, can use the SECURECRT software instead.

"Hint" securecrt software download and installation, refer to the following article: T tool article? 1. Terminal emulation software securecrt 7.3.5 download and installation

① computer Desktop, double-click the SECURECRT Software icon to open the software.

② Mouse Right click on the Session menu, pop-up menu select New session.

The ③ protocol selects the serial port Serial.

④ port number Select input based on the port number actually obtained by the USB conversion line, Baud rate select 9600.

The ⑤ port number can be seen in the system's Device Manager, which shows COM4.

⑥ sets an easily recognizable name for the new Session.

⑦ Double-click the new Session, under normal circumstances you can see the status of the connection on the right, which shows the switch user mode.

Configuring mode conversions

Cisco IOS classifies patterns that perform different commands, and administrators must enter commands to implement this function in the correct mode if they want to implement a function.

The system automatically enters "user mode" after startup, and the user mode prompt is the "greater than Sign" (>) in the back.

"Hint" as long as you enter a question mark (?) in the appropriate configuration mode, you can see the command keyword that can be used in this mode.

The command can be executed in ① user mode.

After you enter the command enable , you can see that the prompt has become a pound sign (#) from the greater than sign, so that the system enters privileged mode.

The command can be executed in ② privileged mode.

Enter the command in privileged mode Configure Terminal , you can see that the prompt has changed from the pound sign to "(config) #" so that the system enters the "global configuration Mode".

The command can be executed in ③ global configuration mode.

Enter the command exit , which can be returned from the global configuration mode to privileged mode.

Enter the command disable , which can be returned from privileged mode to user mode.

"Concept" User mode : User mode is a feature height constrained mode, in this mode, we can not do a lot of configuration, can do very little. Privileged mode : A device can be configured in a very simple way to view information about the device in this mode. Global configuration mode : Has all the functions of management, but for the "local" configuration, you need to go to the global configuration, and then into the corresponding local configuration (such as interface configuration).
