How To Show Cisco Controller Ip Address

This tutorial explains bones bear witness commands (such as show ip route, show ip interfaces brief, bear witness version, prove wink, show running-config, show startup-config, show controllers, etc.) in Cisco router with examples. Learn how to use testify commands in Cisco router to get specific data.

To explain basic router show commands, I will use packet tracer network simulator software. Yous tin utilise any network simulator software or can use a existent Cisco router to follow this guide. There is no difference in output as long as your selected software contains the commands explained in this tutorial.

Create a practice lab equally shown in post-obit figure or download this pre-created practise lab and load in parcel tracer

Download do topology for bones show commands

If require, you can download the latest as well as earlier version of Package Tracer from here. Download Parcel Tracer

In this exercise lab

Device / Interface	Continued To	IP Address
PC0	Router0'due south FastEthernet 0/0	10.0.0.2/255.0.0.0
Router0'south FastEthernet 0/0	PC0	10.0.0.1/255.0.0.0
Router0'southward Serial 0/0/0	Router1's serial 0/0/0	50.0.0.i/255.0.0.0
Router1's Serial 0/0/0	Router0's serial 0/0/0	l.0.0.2/255.0.0.0
Router1's FastEthernet 0/0	PC1	20.0.0.one/255.0.0.0
PC1 Router1's	FastEthernet 0/0	20.0.0.ii/255.0.0.0

RIP Routing protocol is configured on both routers.
Clock rate and bandwidth is assigned on Router0's serial interface 0/0/0.

Above practise lab is simply a recommendation to sympathize the show commands more clearly, it'due south not a requirement to follow this tutorial. You tin can follow this tutorial in a single router or even without router.

Basic Cisco Router Show Commands

Access CLI prompt of router

Utilize enable command to enter in privilege exec way. Cisco IOS supports unique context sensitive help features. We can use this features to list all available commands and parameters those are associated with bear witness command.

Enter bear witness command with ? ( Question marker ) to list all available commands

If prompt returns with parameters excluding <CR> that means it requires more parameters to complete this command.

If prompt returns with <CR> only equally option, that means router does non need any boosted parameters to complete this control. You can execute this command in electric current condition.

Router#show interfaces

This control shows the condition and configuration of interfaces. By default information technology will brandish all interfaces. But you can limit it to particular interface. To view the detail of specific interface you can utilise the following command.

Router#show interface [type slot_# port_#]

For example to view the particular of series 0/0/0 interface on Router0 nosotros will use following control

Output of this command provides several details nigh interface including its status, encapsulation, interface blazon, MTU, last input and output packet etc. First line of output shows the condition of interface. First upward indicates the status of physical layer. Second up refers the data link layer status.

Possible status of physical layer

Upwards: - Interface is receiving physical layer signals.
Down:- Interface is not receiving physical layer signals. This could be happen due to following reasons.
- Cablevision is unplugged
- You lot are using incorrect cable type.
- Attached device is turned off.
Administratively down:- Interface is turned off by using shutdown control.

Possible condition of data link layer

Upwardly:- interface is operational.
Downwardly:- interface is not operational. This could be due to post-obit reasons:-
- Physical layer is down
- Incorrect encapsulation setting
- Wrong clock rate or bandwidth setting
- Wrong keepalives setting

Interface status	Description
Upward and Up	Interface is operational
UP and Down	Cheque data link layer for possible reasons given above
Downwardly and Down	Check physical layer for possible reasons given above
Administratively down and down	Interface is disabled with shutdown control

Second line shows the Hardware type and MAC address of interface.
Third line shows the IP address of interface.
MTU indicates the Ethernet frame size.
BW parameter refers to bandwidth link

Router# testify ip interface cursory

This command provides a quick overview of all interfaces on the router including their IP addresses and status.

Router#prove controllers [type slot_# port_#]

This command is used to check the hardware statistic of interface including clock rate and cable status such equally cablevision is fastened or not. One end of serial cable is physically DTE, and other end is DCE. If cable is attached, it will display the type of cable.

Router#prove flash

This command will display the content of flash retentiveness, used space and bachelor space. By default router stores IOS image file in wink. We can apply this command to bank check the available space in Wink memory while updating / restoring IOS files.

Router#testify version

This command volition brandish data nearly software version of running IOS. Information technology also provides information about configuration setting. Information technology shows electric current configuration register setting that is used to reset the password of router.

Router#prove startup-config

Routers load configuration from NVRAM in startup. This control will display the configuration stored in NVRAM.

Router#testify running-config

Router keeps all running configuration in RAM. This control will display the configuration currently running in RAM.

Router#evidence clock

This command displays current time on router.

Router#show hosts

This command displays names and addresses of the hosts on the network that you can connect.

Router#show users

This command displays users currently continued to the router.

Router#show arp

This command displays ARP enshroud table. ARP tabular array is used to resolve the hardware MAC addresses.

Router#evidence protocols

This command shows the status of configured layer three protocols on the device.

Router#show history

Router keeps a history of used command. This command will list the used command on that level.

Router#show ip route

Routers use routing tabular array to have packet frontwards decision. This control displays routing table.

Show control supports several other parameters to brandish control specific information. Due to length of this commodity we will include them in next articles with their respective topics.
