Body:-Cisco Routers develop Internetwork Operating System(IOS) to manage as well as deal with the components it's managing on.IOS delivers the particular user interface between the user and the hardware, enabling the consumer that will execute that order to configure and handle the nuvi employing 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 really a personality and also text based interface applied to configure as well as monitor your deviceit supports some sort of command parser, when enter is definitely constrained following keying the control IOS parses the command along with details this everyone enterd and inspections intended for correct syntax..There a variety of with obtaining the particular IOS CLI just like utilizing console,auxiliary,telnet,web visitor plus a strong SNMP mnagment station, nevertheless most usual way of being able to view is through console.
IOS facilitates three numerous gain access to modes pertaining to relationship using CLI:
1) User Exec---provides fundamental usage of this IOS like keeping track of plus troubleshooting commands
2) Privilege Exec---provides a high-level management use of the particular IOS,User EXEC mode command could also be utilized during that mode
3) Configuration-----provides commands pertaining to establishing device
1.a User EXEC Mode
The primary admission to the CLI is conducted through this mode. Depending upon the configuration from the router consumer can be caused regarding password. This mode is commonly used with regard to overseeing along with troubleshooting the device, this has a very minimal number of commands.
This mode will be revealed with the prompt as ">".
R1>
Here left for you to your induce can be the nuvi 780 name.
1.b Privilege EXEC Mode:
Giving "enable" order with the earlier mentioned method allows you to input to this mode. If this advantage EXEC password provides already been set, then you will always be prompted for that password.
This manner is actually discovered be the actual prompt when "#".
R1#
In this mode, we could as well use the User EXEC method commands, this setting provides more advanced supervision and also troubleshooting commands. We can't develop commands that will customize the 780 configuration.
1.c Configuration Mode:
Use the "configure terminal" command during Privilege EXEC Mode to help enter for you to this particular mode, when found within the underneath example.
R1#configure terminal
R1(config)#
Prompt at this specific setting is usually "(config)#".
Use this command in this style to alter that configuration with the device.
We cannot check out the particular configuration alterations at this setting in this we will need to get back on Privilege EXEC Mode by simply possibly testing "end" as well as demanding the actual control series CTRL-Z,
1.d Sub-configuration mode:
Configuration manner features a couple of different levels:
a. Global Configuration manner and
b. Sub-configuration. mode
At the actual Sub-configuration mode, this commands which might be entered have an effect on only specific element of the device.
The following will be the different sub-configuration modes as well as his or her similar prompts
Mode prompt
Interface Subconfiguration mode (config-if)#
Subinterface Subconfiguration method (config-subif)#
Line Subconfiguration function (config-line)#
Controller Subconfiguration function (config-controller)#
IP Routing Protocol Subconfiguration function (config-router)#
To get away from a new Sub-configuration manner along with returning that will Global Configuration mode, utilize leave command
2.0 Router Interface Configuration:
Interface Naming
Depending with the nuvi 780 interfaces might be also fixed, modular or both.
For Routers that have merely unchanging interfaces, your program nomenclature is
sort port_#.
If this router while a couple of predetermined serial interfaces they are identify seeing that serial 0 plus serial 1
If your router has modular slots, the particular software nomenclature is much like type slot_#/port_#.
Each position will begin using 0 plus features an original position number.within each slot convey amounts get started at 0 as well as move their technique up.
For instance a modular router by using a couple of pai gow poker has position 0 since earliest position in addition to slot one particular while minute slot. If the primary slot has five serial interfaces they may be together with through 0 that will 3 as well as the that the subsequent position features couple of serial interfaces they're just together with when 0 and also 1 when established within the beneath 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 user interface might be broken down directly into several logical interfaces identified as sub-interfaces. Once the sub-interface is created router will take care of this kind of realistic program as being a natural interface. Below is a sub-interface nomenclature form port_#.subinterface_#
Example
Sub-interface selection 0 using a natural software "serial 0" can be displayed as
serial 0.0
Example 1: Here most people configure the hostname upon a new router.
R1>enable
R1#configure terminal
R1(config)#hostname bangalore
bangalore(config)#
bangalore(config)#exit
bangalore#
Example 2: Here most people configure your IP correct on an interface of any router.
R1>enable
R1#configure terminal
R1(config)#interface serial 0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#exit
R1#
3. RIP Configuration Using Cisco IOS
RIP is your powerful routing protocol. Configuring RIP for a Cisco router is definitely given below. The network 192.168.1.0 will be 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#
