Getting started with switch configuration and switch types

Vswitch configuration and vswitch types are required for beginners to learn basic knowledge about vswitch configurations and vswitch types. Common vswitches include ATM switches and LAN switches.

Switch configuration

The following describes the general Switch configuration process of a Cisco Catlystl900 switch. For a new Catlystl900 switch, you can use its default switch configuration. This is because it is a hardware device that installs software in FlashMemory. When powered on, it must first perform a series of self-checks. After testing all ports, the switch will be in the working state.

At this time, its switch table is empty. It can learn the connection status of devices on each port through self-learning, and record the MAC address of the device in the switch table. When there is information exchange, the switch forwards data according to the switch table.

To facilitate network management, the Catlystl900 switch has a MAC address, so that it can be assigned an IP address and a shielding code. The network administrator must connect to a terminal or simulation terminal through the serial port of the switch to specify an IP address. The default value is 0.0.0.0. After an IP address is specified, the network administrator can perform remote management over the network.

The configuration interface of the Catlystl900 switch is in the menu format. Under the default configuration, all its ports belong to the same VLAN. In many cases, no modification is required.
◆ Connect the serial port of the Microcomputer to the Console port of Cata1yst1900 through the RS 232 cable, run the simulation terminal software, and start Catalyst1900.
◆ Press enter to go to the main menu:
◆ Press the "S" key to enter the system configuration menu: Configuration System name, location, date)
◆ Press "N" in the main menu to enter the network management menu
◆ Configure IP address location for vswitch
◆ Configure SNMP Parameters

Vswitch type

A vswitch is a data link layer device that connects multiple physical LAN network segments to a large network. Similar to a network, vswitch transmission and overflow are based on MAC addresses. Because the switch is implemented by hardware, the transmission speed is very fast. When data packets are transmitted, the switch either uses the storage-forwarding and switching mode or the off-switching mode. There are many types of switches, including ATM switches, LAN switches, and different WAN switches.

Switch Type: ATM Switch

ATMAsynchronousTransferMode) vswitches provide high-speed information exchange and scalable bandwidth capabilities for Working Groups, enterprise network hubs, and many other fields. The ATM switch supports speech, video, and text data applications and can be used to exchange fixed-length information units, also known as elements ). An enterprise network is composed of multiple LANs connected through an ATM hub link.

Switch Type: LAN switch

A lan switch is used to connect multiple lan cidr blocks. It performs dedicated non-conflict communication between network devices and supports conversations between multiple devices. LAN switches are mainly used to exchange data frames at high speed. A 0 Mbps Ethernet is interconnected with a Mbps Ethernet through a LAN switch.
