Common configuration commands for Cisco Routers

Cisco plays a very important role in vro enterprises. It is very important to know some knowledge about common configuration commands of Cisco vrouters. So I studied how to use common configuration commands for Cisco routers. I would like to share them with you here for your reference.

Access-enable allows the router to create a temporary Access list entry in the dynamic Access list
Access-group: Apply the Access control list (ACL) to the interface.
Access-list defines a standard IP ACL
Access-template manually replaces the temporary Access list entry on the connected vro
Appn sends commands to the APPN Subsystem
ATM sig executes ATM signaling commands
B. Manually boot the Operating System
Bandwidth: Set the Bandwidth of the interface.
Banner motd
Bfe emergency manual mode
Boot system specifies the system image loaded when the vro starts.
Calendar
Cd change path
Cdp enable allows interfaces to run CDP protocol
Clear Reset Function
Clear counters Clear interface counters
Clear interface component logic on the restart interface
Clockrate: set the clock rate of the serial port hardware connection, such as the acceptable rate of the network interface module and interface processor.
Cmt enables/disables FDDI connection management
Config-register modify configuration register settings
Configure allows you to enter the existing configuration mode and maintain and save the configuration information on the central site.
Configure memory load configuration information from NVRAM
Configure terminal manual configuration from the terminal
Connect
Copy configuration or image data
Copy flash tftp back up system image files to the TFTP Server
Copy running-config startup-config stores the current configuration in RAM to NVRAM
Copy running-config tftp stores the current configuration in RAM on the network TFTP Server
Copy tftp flash download new image from TFTP server to Flash
Copy tftp running-config download the configuration file from the TFTP Server
Debug debugging
Debug dialer displays the number of interfaces and other information.
Debug ip rip display RIP route selection update data
Debug ipx routing activity displays information about route selection protocol (RIP) Update packets
Debug ipx sap displays SAP Business announcement protocol) Update packet information
Debug isdn q921 shows the access process of layer 2nd of the data link layer on the D-channel ISDN interface of the router.
Debug ppp displays the business and exchange information during the implementation of PPP
Delete File
Deny is used to set conditions for a named ip acl.
Dialer idle-timeout specifies the length of idle time before the line is disconnected.
Dialer map sets a serial interface to call one or more locations
Dialer wait-for-carrier-time specifies how long it takes to wait for a carrier
Dialer-group configures the interfaces of a specified dial-up group to control access.
Dialer-list protocol defines a digital data receiver DDR) the dial-up table controls dialing through a combination of protocols or ACLs and protocols
Dir: displays files on a specified device.
Disable
Disconnect
Enable
Enable password: determine a password to prevent unauthorized access to the vro.

These common configuration commands of Cisco routers are very practical, which can bring us a lot of convenience during the use of routers.
