summary:-Cisco Routers utilize Internetwork Operating System(IOS) to manipulate along with manage your electronics it's running on.IOS offers that software in between the end user and the hardware, enabling your user to execute the order to configure along with handle the device using Command Line Interface (CLI.)
Body:-Cisco Routers utilize the Internetwork Operating System(IOS) to help command as well as control this hardware it's working on.IOS provides the software concerning an individual and also the hardware, enabling the user to be able to implement your command in order to configure and take care of the 780 utilizing Command Line Interface (CLI.)
Cisco IOS Features:
1. Command Line Interface (CLI)
a. User EXEC Mode
b. Privileged EXEC Mode
c. Global Configuration Mode
d. Sub-Configuration Mode
2. Router Interface Configuration
3. RIP Configuration Using Cisco IOS
1. Command Line Interface (CLI)
The CLI is usually a personality or perhaps text centered program employed to configure or maybe observe the deviceit supports a command parser, whenever type in will be pressed immediately after inputting the particular control IOS parses the actual order plus variables that people enterd in addition to determines intended for correct syntax..There are many involving being able to access the actual IOS CLI like applying console,auxiliary,telnet,web cell phone browser plus an SNMP mnagment station, although most popular knack of getting at is definitely through console.
IOS supports some several admittance modes pertaining to interaction with CLI:
1) User Exec---provides essential having access to your IOS such as following in addition to troubleshooting commands
2) Privilege Exec---provides a high-level software use of the IOS,User EXEC style command is usually used with this particular mode
3) Configuration-----provides commands pertaining to making device
1.a User EXEC Mode
The first access to the CLI is complete by means of this mode. Depending upon the actual configuration in the router person might be advised for password. This style is commonly used with regard to monitoring plus troubleshooting your device, it has a really limited group of commands.
This setting can be identified through the prompt seeing that ">".
R1>
Here remaining to the prompt is usually your system name.
1.b Privilege EXEC Mode:
Giving "enable" command line at the over mode lets you get into to the current mode. If your privilege EXEC password includes already been set, in which case you might be prompted for your password.
This manner is definitely recognized always be the actual punctual as "#".
R1#
In this mode, we can also use the User EXEC manner commands, this function offers more advanced software along with troubleshooting commands. We are not able to use the actual requires that modify the machine configuration.
1.c Configuration Mode:
Use the "configure terminal" control from Privilege EXEC Mode in order to enter in to the mode, while revealed inside below example.
R1#configure terminal
R1(config)#
Prompt at this mode is "(config)#".
Use the command within this setting for you to transform the particular configuration in the device.
We is unable to watch that configuration variations at the following mode due to this we have going returning to Privilege EXEC Mode by both testing "end" or pushing the deal with routine CTRL-Z,
1.d Sub-configuration mode:
Configuration method provides a couple distinct levels:
a. Global Configuration mode and
b. Sub-configuration. mode
At that Sub-configuration mode, the commands which might be inserted change simply precise element of that device.
The subsequent include the different sub-configuration modes in addition to his or her equivalent prompts
Mode prompt
Interface Subconfiguration function (config-if)#
Subinterface Subconfiguration setting (config-subif)#
Line Subconfiguration method (config-line)#
Controller Subconfiguration mode (config-controller)#
IP Routing Protocol Subconfiguration function (config-router)#
To give your Sub-configuration setting along with come back to Global Configuration mode, make use of the stop command
2.0 Router Interface Configuration:
Interface Naming
Depending around the gadget interfaces is usually also fixed, modular or perhaps both.
For Routers who have solely predetermined interfaces, the actual program nomenclature is
kind port_#.
If this router as not one but two unchanging serial interfaces these are name since serial 0 and serial 1
If the router offers modular slots, the software nomenclature is like type slot_#/port_#.
Each slot will begin along with 0 as well as has a distinctive slot number.within each and every position port numbers begin from 0 in addition to step their manner up.
For instance a modular router with two pai gow poker includes slot 0 as first position and position just one when subsequent slot. If the actual primary position includes five serial interfaces they're numbered from 0 that will a few and also the in case the next position offers couple of serial interfaces there're using because 0 along with 1 seeing that shown around the underneath representation.
First slotSerial 0/0, Serial 0/1, Serial 0/2, Serial 0/3
Second slotserial 1/0,serial 1/1
Sub-interfaces
Router's physical software is often pulled apart towards several logical interfaces labeled sub-interfaces. Once the actual sub-interface is established router will treat this kind of plausible interface just like a bodily interface. Below will be sub-interface nomenclature sort port_#.subinterface_#
Example
Sub-interface range 0 using a natural interface "serial 0" is available as
serial 0.0
Example 1: Here we configure this hostname with a router.
R1>enable
R1#configure terminal
R1(config)#hostname bangalore
bangalore(config)#
bangalore(config)#exit
bangalore#
Example 2: Here most people configure the IP tackle about a strong interface of the router.
R1>enable
R1#configure terminal
R1(config)#interface serial 0
R1(config-if)#ip handle 192.168.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#exit
R1#
3. RIP Configuration Using Cisco IOS
RIP is usually a active routing protocol. Configuring RIP on a Cisco router is actually given below. The network 192.168.1.0 is enabled with regard to RIP.
R1>enable
R1#configure terminal
R1(config)#router ripR1(config-router)#network 192.168.1.0R1(config-router)#exit
R1(config)#exit
R1#
