Configuring a Cisco Router Flashcards

1
Q

The term Ethernet interface refers to any type of Ethernet interface. For example, some Cisco routers have an Ethernet interface that is capable of only 10 Mbps, so to configure this type of interface, you would use the interface Ethernet interface-identifier configuration command.

Q

Serial interfaces are the second major type of physical interfaces on Cisco routers. To support point-to-point leased lines and Frame Relay access-link standards, Cisco routers use serial interfaces. You can then choose which data link layer protocol to use, such as High-Level Data Link Control (HDLC) or Point-to-Point Protocol (PPP) for leased lines or Frame Relay for Frame Relay connections, and configure the router to use the correct data link layer protocol. Use the interface serial interface-identifier command when configuring these types of interfaces.

Q

Is a virtual interface that resides on a router. It is not connected to any other device. Loopback interfaces are very useful because they will never go “down,” unless the entire router goes down or the interface is manually disabled.

18
Q

Shows the bandwidth of the interface in kilobits per second. The bandwidth parameter is used to compute routing protocol metrics and other calculations.

Q

Displays the load on the interface as a fraction of 255 (255/255 is completely saturated). This parameter is used to compute routing protocol metrics and other calculations.

Q

Shows the average number of bits and packets that the interface transmitted per second in the last 5 minutes.

A

24
Q

Is a Cisco proprietary protocol that discovers basic information about neighboring Cisco devices without needing to know the passwords for the neighboring devices. To discover information, routers and switches send Cisco Discovery Protocol messages out each of their interfaces. Devices that support Cisco Discovery Protocol learn information about other devices by listening for the advertisements that these devices send.

A

Cisco Discovery Protocol (CDP)

25
Q

Which is a standardized, vendor-independent discovery protocol that discovers neighboring devices from different vendors. The Institute of Electrical and Electronics Engineers (IEEE) standardized this protocol as the 802.1AB standard.

A

Link Layer Discovery Protocol (LLDP)

26
Q

Output varies among different types of devices, but the available information is generally consistent across devices.

A
