What else can I help you with?
Which two commands can a technician use to determine whether router serial ports have ip addresses that are assigned to them?
"show interfaces" "show ip interface brief"
What are the types of network interface card?
Gigabit Ethernet interface Controller interface Serial interface Multilink Group interface MFR (Multilink Frame Relay bundle interface) Dialer interface Loopback interface Tunnel interface ATM interface
1what type of interface connects a device to the system unit by transmitting data one bit at a time?
A serial port is an interface in which one bit of data is transmitted at a time.
In an IPv4 environment what information is used by the router to forward data packets from one interface of a router to another?
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
What is the convention used for naming of the serial port 0 on a router is?
S0/0.
What is the result of using the clock rate 56000 command at the serial interface of the router?
The interface is configured as a DCE device.
Line protocol in down then what you do?
there may be the issue with the layer 2 protocol like hdlc or ppp is not configured or wrongly configured if the interface is serial interface.
What command is used to verify if a serial nterface is operating as a DTE DCE?
To verify if a serial interface is operating as a Data Terminal Equipment (DTE) or Data Communication Equipment (DCE), you can use the command show controllers in Cisco IOS. This command displays detailed information about the serial interface, including whether it is configured as a DTE or DCE. The output will typically indicate the role of the device, and a DCE interface will often show the clock rate configuration.
What is difference between serial interface and Ethernet interface?
The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.
What command is used to set data speed on a router's serial port to 56 kbps?
The command is: clock rate 56000 So it will appear on the command line interface as: Router(config-if)# clock rate 56000 Reference: Networking by Jeffrey Beasley Chapter 6 page 216.
If a router receives a packet that it does not know how to forward what type of route must be configured on the router to prevent the router from dropping it?
The default route must be configured such as: Ip route 0.0.0.0 0.0.0.0 serial 0/0 etc.
Cisco router 2801 serial port is manually down how you can enable this port?
router> enablerouter# configure terminalrouter(config) interface serial (interface number)router(config-if) no shutdownrouter(config-if) endrouter#substitute (interface number) for the actual int number.. eg serial 0/1you can find the number of the interface by using show interfaces from privileged mode
What do you mean by admin down in router serial interface?
admin down basically means that an adminstrator shutdown the interface for any number of reasons, and if the admin wanted to, they could bring it back up with the 'no shutdown' command.
Why set clock rate in router?
To configure the clock rate for the hardware connections on serial interfaces such as network interface modules (NIMs) and interface processors to an acceptable bit rate, use the clock rate interface configuration command. Use the no form of this command to remove the clock rate if you change the interface from a DCE to a DTE device. Using the no form of this command on a DCE interface sets the clock rate to the hardware-dependent default value.
Which encapsulation protocol when deployed on a Cisco router over a serial interface is only compatible with another Cisco router?
HDLC
What equipment does the DCE end of the serial cable usually connect?
It would connect to the serial port interface of a router.
What must be configured to establish a serial link between two routers that are directly connected?
To establish a serial link between two directly connected routers, you must configure the appropriate interface settings on both routers, including the serial interface type and IP addressing. This involves enabling the serial interfaces and assigning them IP addresses within the same subnet. Additionally, you may need to set the encapsulation type (e.g., HDLC or PPP) and ensure that clock rates are configured if one router is designated as the DCE device. Finally, verify the link with commands like ping or show ip interface brief to ensure connectivity.
