Cisco switch commands

A large number of commands are available on Cisco routers , as well as many different protocols and features that can be used to establish a network. This section will familiarize you with some of the basic router commands that are commonly used, as well as some typical router management tasks in the included labs. The following commands are used to gather information on a Cisco IOS Software-based router when attempting to learn basic information about a router, or possibly troubleshooting protocol-independent problems: show version show running-config show interfaces show logging show tech-support Let's examine these commands further to see how they can be used to obtain valuable information. You will use the show version command in the simulation environment. This command displays the configuration of the system hardware, the software version, and the names and sources of configuration files and the boot images. This command also displays information about how the system was last started and how long the router has been running since that start. Sample output from the show version command follows:. This software has many different versions of the Cisco IOS Software, each of which supports a variety of features. The version of Cisco IOS Software on the router plays a major role in dictating the capabilities and services of the router. Router Uptime and System Restart The router uptime can be checked to make sure the router has been in continuous operation since it was last restarted. If the uptime is inconsistent with the last known router maintenance, the router may have restarted because of problems with the electrical circuit it is connected to, or because of problems with the router itself. The "System restarted by" line displays a log of how the system was last booted, whether by normal system startup or because of a system error. The following display is an example of a system error that is generally the result of an attempt by the router to access a nonexistent address: System restarted by bus error at PC 0xC4CA, address 0xC0C0 Interface Hardware Inventory The interface hardware inventory should include all interface processors installed in the router. If any interfaces that are installed in the router do not show up in the inventory, there may be hardware problems with the interface processor itself, or the router may be running a version of the Cisco IOS Software that does not support that interface type.

The duplex mode governs the data transmission between the switches and the endpoint. Note Copies of the CMS pages that you display are saved in your browser memory cache until you exit the browser session, cisco switch commands.

When you start a session, you begin in user mode, often called user EXEC mode. Only a limited subset of the commands are available in user EXEC mode.

Cisco switches provide outstanding performance, security, scalability, and cost-efficiency for any network type. They are not ordinary plug-and-play devices that do not need configuration or involvement when resolving issues. However, Cisco switches do require an initial setup, ongoing monitoring, and maintenance. How to configure a Cisco switch? Catalyst series is a well-known family of enterprise-grade network equipment, which varies from wireless controllers, switches, and wireless access points. Catalyst switches use the IOS as their operating system. In addition, all Cisco switches come with LEDs that let you know the current state of your switch.

Cisco switch commands

Cisco switches can be used as plug-and-play devices out of the box but they also offer an enormous amount of features. Although the main purpose of the switch is to provide inter-connectivity in Layer 2 for the connected devices of the network, there are myriad features and functionalities that can be configured on Cisco Switches. In the following Cisco Switch Commands Cheat Sheet, I have tried to include the most important and frequently-used CLI commands that Cisco professionals encounter in real world networks. I know that the list is not exhaustive but I believe that the most useful commands are included.

Command Default No default behavior or values. You entered the command incorrectly. To exit to global configuration mode, enter exit. As the name suggests, all the interface processors in a router share this memory, and performance problems can result if there is not enough. Configure System Location: Switch-A config banner motd?

OutOctets Number of transmitted octets. In this task, we configure telnet services on a switch to access it from anywhere remotely. The following example shows a sample output from the switch show ip route command when IP routing is enabled:. The IOS provides a history or record of commands that you have entered. In the absence of entries in the dynamic routing table or when there is no specific route available, the switches are capable of forwarding packets via the configured static route. Reenables the enhanced editing mode for the current terminal session in privileged EXEC mode. If your switch is already configured, you can access the CLI through a local console connection or through a remote Telnet session, but your switch must first be configured for this type of access. Need to implement these Cisco switch commands on an actual unit? You're not alone; we all need a refresher once in a while -- so, here's your refresher course. Connect the switch console port to a management station or dial-up modem, or connect the Ethernet management port to a PC. Displays dynamic address.
