Cisco Devices Flashcards
What are the two ways to make a connection to a cisco device
Local connection and remote connection
When first configuring a cisco device wht type of connection must you use first?
Local connection
What type of cable was needed to connect to a cisco device?
RJ45 to DB-9 serial port
What is another name for the console cable
roll over cable
Cisco devices dont have hard drives so how do they store information
Through the following kinds of RAM RAM Flash ROM NVRAM
What does the RAM of a cisco device store
Running configuration, ARP tables, Routing tables
What is stored in the Flash memory of a cisco device
IOS software storage location
What is stored in the ROM
POST and boot loader software
What is stored on NVRAM
start up configuration file
What is the first step in the boot process of a cisco device?
POST
What is the second step of the boot process of a cisco device?
ROM loads boot loader software and searches for IOS
What is the third step of the boot process on a cisco device
IOS is loaded from Flash memory
What is the fourth step in the boot process of a cisco device?
Startup config file is loaded from NVRAM
What type of server should you use to back up a Cisco IOS software and configuration files
TELNET FTP server
What is the first step in backing up an IOS image on a TFTP server
Verify connectivity to the TFTP server using a ping test
What is the second step in backing up an IOS image on a TFTP server
Verify that there is enough space on the server for the IOS software image. This can be done using the show flash0: command.
What is the third step in backing up an IOS image on a TFTP server
Copy the image to the TFTP server using the copy source-url destination-url command.
What is the first step in upgrading an IOS device
Select the correct image file either from your TFTP server or from the Cisco site. If you’re pulling from the Cisco site, it is best to store it on your TFTP server for use on additional devices. Be sure to review the naming convention for platform, features, and software.
What is the second step in upgrading an IOS device
Verify connectivity to the TFTP server using a ping test.
What is the third step in upgrading an IOS device
Verify that there is enough space on the device that is being upgraded.
What is the fourth step in upgrading an IOS device
Copy the IOS image file from the TFTP server using the copy command.
Describe user exec mode in the cisco IOS terminal
provides the most basic level of access to a Cisco device. Users logged into this mode have read-only access to the device and access to information gathering permissions such as ping, telnet, traceroute, and connect. Users are unable to make long-term changes while in user mode.
Describe privileged exec mode in the cisco IOS terminal
provides a user with editing capabilities
Describe Global configuration mode in the cisco IOS terminal
provides advanced access to device configurations.
Describe ROMMON mode in the cisco IOS terminal
is a command line mode that is used to recover a lost or forgotten password, to reinstall the IOS, or to format the flash file system
What mode is this Router>
User Exec mode
What mode is this Router# and how do you enter and exit it
Privileged Exec mode. enter by typing enable and exit by typing disable
What mode is this Router(config)# and how do you enter and exit it
Global configuration mode and enter it by typing config terminal and exit by typing exit
What does the show command do
used to display information about the status, configurations, and other specific aspects of a Cisco device.
What does the show-running configuration command do
Configuration that is currently running on the device’s memory
What does the command show startup-configuration do
shows The configuration that will be loaded on restart.
What does the show version command do
Hardware configuration
Running IOS version
ROM bootstrap version
RAM and processor information
What does the command show flash
Size of the configuration files
Available flash memory
Information for all IOS image files stored on the device
What does the command show history do
Commands in the command history list.
What does the command show clock
The current time and date of the device.
What does the command show interface do
Information about a router’s interface including:
Interface status (whether it’s up or down)
Utilization
Protocol status on the interface
Errors
Maximum transmission unit (MTU)
what does the command show ip interface
Information about the configuration of the IP protocols on each interface, including:
IP address
Layer 2 status
Layer 3 status
What does the command show ip route do
Networks the router can reach
Metric
Route to each network
Where can a cisco device load a configuration file from
NVRAM (startup-configuration file, by default value 0x2102)
TFTP server
What does the command copy run start do
Saves the contents of the running-config file to NVRAM.
what does the command copy start run do
Copies the startup-config file into RAM.
what does the command copy run tftp do
Saves the contents of the running-config file to a TFTP server.
what does the command copy start tftp do
Saves the contents of the startup-config file to a TFTP server.
what does the command copy tftp start do
Copies a configuration file from the TFTP server into NVRAM.
What does the command copy tftp run do
Copies a configuration file from the TFTP server into RAM.
what does the command copy flash tftp do
Copies the IOS image to the TFTP server. When using this command, you will be prompted for the destination file name and address.
What does the command erase flash do
Deletes the contents of Flash memory (deletes the IOS image).
What does the commans erase start do
Erases the contents of the startup-config file.
what does the command erase nvram do
Deletes the contents of NVRAM (which also erases startup-config).
How do you calculate total dram on a cisco device
Add the ram amount from the result of the show startup-configuration command and then divide by 1024
