This tutorial explains fundamental display regulates (such as display ip route, present ip interfaces brief, display variation, present flash, present running-config, present startup-config, present controllers, etc.) in Cisco router with examples. Learn just how to use show commands in Cisco rexternal to get certain indevelopment.
You are watching: A. which command displays the statistics for all interfaces configured on a router?
To explain fundamental rexternal show regulates, I will certainly use packet tracer network-related simulator software application. You deserve to use any kind of network-related simulator software application or can use a actual Cisco router to follow this overview. There is no difference in output as lengthy as your schosen software contains the commands explained in this tutorial.
Create a practice lab as presented in following figure or downfill this pre-created exercise lab and also fill in packet tracer
Download exercise topology for standard present commands
If need, you have the right to downpack the latest as well as earlier version of Packet Tracer from here. Download Packet Tracer
|Device / Interface||Connected To||IP Address|
|PC0||Router0"s FastEthernet 0/0||10.0.0.2/255.0.0.0|
|Router0"s FastEthernet 0/0||PC0||10.0.0.1/255.0.0.0|
|Router0"s Serial 0/0/0||Router1"s serial 0/0/0||22.214.171.124/255.0.0.0|
|Router1"s Serial 0/0/0||Router0"s serial 0/0/0||126.96.36.199/255.0.0.0|
|Router1"s FastEthernet 0/0||PC1||188.8.131.52/255.0.0.0|
RIP Routing protocol is configured on both routers. Clock rate and bandwidth is assigned on Router0’s serial interconfront 0/0/0.
Above practice lab is just a referral to understand also the display commands even more clearly, it’s not a need to follow this tutorial. You can follow this tutorial in a solitary rexternal or even without rexternal.
Access CLI prompt of router
Use enable command also to enter in privilege exec mode. Cisco IOS supports unique context sensitive assist functions. We deserve to use this features to list all available regulates and parameters those are connected through show command also.
Go into show command also through ? ( Question note ) to list all accessible commands
If prompt retransforms with parameters excluding that means it needs even more parameters to complete this command.
If prompt returns via only as choice, that means rexternal does not need any type of extra parameters to complete this command also.You have the right to execute this command also in current problem.
This command also reflects the condition and also configuration of interfaces. By default it will display screen all interencounters.But you have the right to limit it to specific interconfront. To see the detail of specific interchallenge you deserve to use the following command also.
For example to view the detail of serial 0/0/0 interchallenge on Router0 we will usage complying with command
Output of this command gives a number of details around interface including its standing,encapsulation, interface kind, MTU, last input and output packet and so on. First line of output shows the standing of interface. First up shows the standing of physical layer. Second up refers the data attach layer standing.Possible standing of physical layer UP: - Interconfront is receiving physical layer signals. Down:- Interchallenge is not receiving physical layer signals. This can be happen due to complying with factors. Cable is unplugged You are making use of wrong cable type. Attached gadget is turned off. Administratively down:- Interface is turned off by using shutdown command also.Possible standing of information connect layer UP:- interface is operational. Down:- interchallenge is not operational. This could be because of following reasons:- Physical layer is dvery own Incorrect encapsulation setting Incorrect clock price or bandwidth setting Incorrect keepastays setting
|UP and UP||Interface is operational|
|UP and Down||Check information attach layer for possible factors offered above|
|Down and Down||Check physical layer for feasible factors provided above|
|Administratively dvery own and down||Interchallenge is disabled through shutdown command|
Second line reflects the Hardware form and MAC resolve of interface. Third line shows the IP address of interconfront. MTU suggests the Ethernet frame size. BW parameter describes bandwidth linkRouter# present ip interface brief
This command also gives a quick oversee of all interencounters on the router including their IP addresses and also status.
This command is offered to check the hardware statistic of interchallenge including clock price and cable status such as cable is attached or not. One end of serial cable is physically DTE, and also various other end is DCE. If cable is attached, it will certainly display the type of cable.
This command will display screen the content of flash memory, offered room and obtainable room. By default rexternal stores IOS image file in flash. We can usage this command also to inspect the easily accessible area in Flash memory while updating / restoring IOS papers.
This command will display indevelopment about software program variation of running IOS. It also offers information about configuration setting. It mirrors existing configuration register establishing that is offered to reset the password of router.
Routers fill configuration from NVRAM in startup. This command will certainly screen the configuration stored in NVRAM.Router#present running-config
Router keeps all running configuration in RAM. This command also will display the configuration presently running in RAM.Router#display clock
This command display screens current time on router.Router#present hosts
This command display screens names and addresses of the hosts on the network that you deserve to connect.Router#display users
This command display screens customers currently connected to the rexternal.Router#present arp
This command display screens ARP cache table. ARP table is offered to deal with the hardware MAC addresses.Router#present protocols
This command also reflects the condition of configured layer three protocols on the gadget.Router#display history
Rexternal keeps a background of offered command. This command will list the used command on that level.Router#present ip route
Routers usage routing table to take packet forward decision. This command displays routing table.

Sjust how command also supports several various other parameters to display screen command specific indevelopment. Due to length of this short article we will certainly incorporate them in next write-ups through their respective topics.
