Note: All CLI commands, need to be entered by "SSH". The first command there could mitigate the exposure caused by lack of physical security. <0-2147483> Timeout in seconds , Branch(config-line)#exec-timeout 20 30 ? After that, they gradually configure different functions and different components of the router. End with CNTL/Z.Router(config)#Router(config)#hostname BranchBranch(config)#^ZBranch#*Feb 4 20:09:54.192: %SYS-5-CONFIG_I: Configured from console by consoleBranch#. Some of them need to execute into "configure terminal" mode before the command will be accepted. These commands show how to do it. The first status is layer 1, the second status is layer 2, and so you can see here some of the combinations that will represent a different overall status of the interface. We know that here at privileged mode, we can go into global configuration by doing the config T, and then from there, to further other configuration modes like interface configuration mode, like that, for that particular interface. This is again what is called the startup configuration. The exec-timeout command allows you to set up a time out for command-line interface shells. Still have trouble with your device? Branch(config-line)#logging synchronousBranch(config-line)#endBranch#wrBuilding configuration...[OK]Branch#. If you would like to reset the device to the factory default configuration, the simplest way is to log in to CLI mode and use the command below to reset the device: Please use Putty on Windows or a similar SSH client to login into your switch. That is the command to assign an interface, a description, and as you can imagine, it is an interface configuration mode command. For users connecting to the router, a good banner when they log in or when they access via any of the access lines will be an effective tool to convey the message of policies, access times, or support information. ZLD Based. If both components are up, then status is operational. CLI Documentation Full. We will see configuration examples for basic interface components including IP addresses and then an overview of the show commands to verify proper configuration and operations. Router show interface Command Multiple commands are available to verify your configuration; show interfaces is perhaps one of the commands that displays the most information in its output. At the command-line interface, the first word you see is the host name. Disclaimer: This site is in not affiliated with Cisco Systems, Inc. Useful stuff. For example, the host name of the router will be used as your router prompt. Typically, the interface identifier will depend on the type of router we have and so there are some fixed configuration routers that will simply have Ethernet 0 as an example or Serial 0 as another example. In routers, again, all interfaces that transport IP will need one; this also helps the router in defining the topology of the directly connected networks and be able to advertise those networks to other devices via routing protocols. Interfaces are the door to other networks and are one of the things that makes the router a router, the device capable of connecting multiple segments, so their configuration is going to be critical. Feel free to contact us if you have any further questions or concerns. ZYWALL USG 100,ZYWALL USG 1000,ZYWALL USG 20 (view more model name). Open the browser and enter the IP-address of the device. If you want to configure specific components, then you would have to go into that components configuration mode from global configuration. At some point, during troubleshooting or during change management, administrators may want to bring the interface down administratively. Another command that may come handy is how to break, or abort, certain things. The shut down command in interface configuration mode disables the interface, while the no version of the same command will enable the interface. If you want to navigate back and forth between modes, exit takes you one mode back and Ctrl+Z takes you all the way back to privileged EXEC mode with no regards to your location. Now from here, we cannot do show commands initially because those belong to the EXEC mode and we are in interface configuration mode.

One possible status is down and this could happen due to lack of service or signal on a certain interface or due to misconfigurations. You go from user to privilege using the enable command and then from there you can only do monitoring and maintenance commands.
