Type of Router Configuration Modes :
1. Enable Mode
2. Privileged Mode
3. Configuration Mode
Prior to bouncing into the order line interface (CLI) of the Cisco switch, it is essential to comprehend the different order modes accessible. Believe the order mode to be a level where you can carry out unambiguous roles. On the off chance that you are not at the right level, you can't carry out the right role (to arrange the switch). This is an exceptionally worked on clarification yet will check out as every mode is examined. Coming up next are order modes on a Cisco switch:
■ ROM screen mode — The ROM screen mode is the mode the switch boots to on the off chance that it can't find a legitimate framework picture. You possibly need to utilize this mode assuming you really want to change the framework boot boundaries to incorporate resetting the framework secret phrase. On the off chance that the switch has a functioning picture introduced, you really want to press the Break key during the initial 60 seconds of the switch boot succession.
■ Client EXEC mode — The client EXEC mode is the mode that you associate with as a matter of course. On the off chance that the switch is designed with a secret word, you are provoked for the secret phrase and given three endeavors to give the right secret word. You will realize that you are in the client EXEC mode in light of the fact that the switch shows the host name followed by a right-point section (>) image.
RouterA>
In the client EXEC mode, you can carry out restricted roles to really take a look at the situation with the switch yet can't change the switch setup. To leave the client EXEC mode, utilize the order logout.
■ Special EXEC mode — To get from the client EXEC mode to advantaged EXEC mode, utilize the empower order. If an empower secret phrase (or even better, empower secret key) has been designed (and it ought to have), you are again provoked for a secret word and given three endeavors. In this mode, the switch shows its host name followed by the hash (#) image.
RouterA> empower
RouterA#
In the favored EXEC mode, you can carry out every one of the roles that were accessible in the client EXEC mode yet at the same time can't make any arrangement changes. You do, nonetheless, approach show and troubleshoot orders that are not accessible in the client EXEC mode. The special EXEC mode is the way to the worldwide arrangement mode. To get back to the client EXEC mode, utilize the order debilitate.
RouterA# impair RouterA>
■ Design modes and submodes — There are various setup modes. Every one of these makes changes to the gadget design. To guarantee that those arrangement changes are not lost assuming the switch reboots, you should duplicate the running setup to the startup design. The sort and number of setup submodes relies upon the kind of switch, the IOS variant, and the parts introduced on the switch.
— Worldwide design mode — The order for getting to the worldwide arrangement mode is design terminal. In the worldwide design mode, the switch keeps on showing its host name followed by (config) and the # image.
RouterA# design terminal
RouterA(config)#
The worldwide design mode is where you can make "worldwide" changes to the arrangement of the switch. An extremely normal illustration of a worldwide design is the production of an entrance list. From the worldwide setup mode, you can move to a place that empowers you to design explicit parts of the switch, like the switch interfaces, VPN parts (isakmp, crypto, etc), CLI associations (line), AAA server gatherings, and some more. To exit to the special worldwide design mode, utilize the key blend Ctrl-Z or type the order end.
RouterA(config)# end RouterA#
— Interface design mode — From the worldwide setup mode, the order for getting to the connection point arrangement submode is point of interaction interface-type interface-number. The switch shows its host name followed by (config-if) demonstrating that it is in the connection point setup mode.
RouterA(config)# interface Ethernet 0
RouterA(config-if)#
Right now, you are prepared to design the connection point that you have chosen. In the event that you are arranging subinterfaces, you really want to utilize a similar order to enter the subinterface setup mode.
RouterA(config)# interface Ethernet 0.1
RouterA(config-subif)#
It is likewise conceivable to enter the subinterface setup mode from the connection point design mode because of a regressive order interface.
RouterA(config-if)# interface Ethernet 0.1
RouterA(config-subif)#
— Line design mode — Another arrangement submode that should be arranged is the line setup. This is the mode used to arrange the CLI admittance to the switch. The order for getting to the line arrangement mode from the worldwide setup mode is line type number.
RouterA(config)# line con 0 RouterA(config-line)#
To leave the arrangement mode and return to the advantaged EXEC mode, utilize the key mix Ctrl-Z or type the order end.
RouterA(config-subif)# end RouterA#
To get back to the worldwide design mode, type the order exit. (This order works for both point of interaction setup and subinterface arrangement modes.)
RouterA(config-subif)# exit RouterA(config)#
NOTE The order prompts utilized in these models are the default prompts. It is feasible to change the framework brief (>, #) by utilizing the brief order while in the worldwide arrangement mode.
For a rundown of the accessible orders in every design, you can utilize the question mark (?). This is maybe the most valuable order composed into the Cisco IOS Software. If you are not totally acquainted with the right linguistic structure of an order, it is feasible to enter a part of the order followed by ?. The switch then, at that point, gives you the right language structure. Table 4-2 tells the best way to explore between modes while arranging the switch.

Order
Depiction
Router> empower Password: ********
Enter the switch in the client EXEC mode. Utilize the empower order and the right secret key to enter the special EXEC mode.
Router# design terminal
Enter the worldwide design mode.
Router# (config) ip steering
Empower IP steering on the switch.
Router# (config) hostname RouterA
Design the switch have name to RouterA.

Depiction
RouterA# (config) interface Ethernet 0/0
Enter the point of interaction arrangement mode.
RouterA# (config) ip address 10.10.10.254 255.255.255.0
Design eth0/0 for 10.10.10.254/24.
RouterA# (config) no closure
The no closure order guarantees that the point of interaction is empowered.
RouterA# (config) exit
Setup complete, exit to worldwide design mode.
RouterA# (config) end or
RouterA# (config) Ctrl-Z
Arrangement complete, exit to advantaged EXEC mode.
NOTE Some orders change contingent on the switch series and Cisco IOS Software variant.
