summary:-Cisco Routers utilize the Internetwork Operating System(IOS) to overpower and also manage that hardware it truly is running on.IOS gives the program somewhere between an individual and the hardware, permitting a computer owner that will execute that command to be able to configure and control the nuvi 780 implementing Command Line Interface (CLI.)
Body:-Cisco Routers make use of the Internetwork Operating System(IOS) to manage plus manage your components the idea is going on.IOS gives the program involving a computer owner along with the hardware, granting the user to help implement the particular command in order to configure plus take care of these devices applying 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 a nature or copy dependent interface employed to configure or monitor the actual deviceit can handle a command parser, when ever enter can be tighten up after typing your command IOS parses the actual order in addition to parameters of which a person enterd and also checks regarding right syntax..There are lots of involving accessing that IOS CLI similar to utilizing console,auxiliary,telnet,web internet browser and also an SNMP mnagment station, but most common means of opening is by means of console.
IOS sustains three diverse obtain modes regarding conversation by using CLI:
1) User Exec---provides simple access to that IOS like checking and troubleshooting commands
2) Privilege Exec---provides your high-level operations having access to the actual IOS,User EXEC function command can even be used at this mode
3) Configuration-----provides instructions to get establishing device
1.a User EXEC Mode
The initial entry to this CLI is finished through this particular mode. Depending upon the configuration belonging to the router customer could possibly be instigated regarding password. This mode is commonly utilized intended for keeping track of and troubleshooting your device, it's a really restricted set involving commands.
This method is actually recognized through the fast as ">".
R1>
Here remaining to the prompt is usually the actual machine name.
1.b Privilege EXEC Mode:
Giving "enable" command on the over mode why don't we you input to the mode. If the freedom EXEC password has been set, then you will possibly be advised to the password.
This setting is identified be the punctual since "#".
R1#
In this kind of mode, we are able to also utilize the User EXEC function commands, this style possesses additional state-of-the-art direction and troubleshooting commands. We can not utilize commands this change the nuvi 780 configuration.
1.c Configuration Mode:
Use that "configure terminal" control at Privilege EXEC Mode for you to enter in to this mode, as demonstrated in the down below example.
R1#configure terminal
R1(config)#
Prompt at this function is "(config)#".
Use the actual command within this function that will switch your configuration in the device.
We can't perspective the configuration changes at this particular function for this we must settle for Privilege EXEC Mode through either testing "end" or depressing this control string CTRL-Z,
1.d Sub-configuration mode:
Configuration setting includes two distinct levels:
a. Global Configuration manner and
b. Sub-configuration. mode
At your Sub-configuration mode, the actual commands that happen to be joined affect only specific element of the actual device.
The using include the several sub-configuration settings as well as their corresponding prompts
Mode prompt
Interface Subconfiguration mode (config-if)#
Subinterface Subconfiguration mode (config-subif)#
Line Subconfiguration setting (config-line)#
Controller Subconfiguration manner (config-controller)#
IP Routing Protocol Subconfiguration method (config-router)#
To leave a new Sub-configuration style along with return to Global Configuration mode, utilize the get out of command
2.0 Router Interface Configuration:
Interface Naming
Depending within the device interfaces could be sometimes fixed, modular or perhaps both.
For Routers who have simply permanent interfaces, your software nomenclature is
kind port_#.
If that router as two unchanging serial interfaces they're name as serial 0 plus serial 1
If your router offers modular slots, the actual user interface nomenclature is compared to sort slot_#/port_#.
Each slot begins having 0 along with incorporates a unique slot number.within each slot opening numbers commence at 0 plus transfer their approach up.
For case a modular router having two slots includes slot 0 as earliest slot and position 1 as minute slot. If the first slot features several serial interfaces these are together with through 0 to help three or more plus the if the minute slot offers 2 serial interfaces they're by using numbers seeing that 0 in addition to 1 as demonstrated within 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 actual interface is often broken down towards multiple reasonable interfaces referred to as sub-interfaces. Once your sub-interface is created router will treat this specific valid software the same as a new natural interface. Below may be the sub-interface nomenclature form port_#.subinterface_#
Example
Sub-interface variety 0 with a real interface "serial 0" is showed as
serial 0.0
Example 1: Here we all configure the hostname over a router.
R1>enable
R1#configure terminal
R1(config)#hostname bangalore
bangalore(config)#
bangalore(config)#exit
bangalore#
Example 2: Here many of us configure your IP deal with on an interface of a 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 dynamic routing protocol. Configuring RIP on a Cisco router can be provided below. The multilevel 192.168.1.0 will be allowed for RIP.
R1>enable
R1#configure terminal
R1(config)#router ripR1(config-router)#network 192.168.1.0R1(config-router)#exit
R1(config)#exit
R1#
