What is the default encapsulation type on a synchronous serial interface?
HDLC
What is the default encapsulation for serial interfaces on Cisco routers?
HDLC
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
Which data link layer encapsulation protocol is used by default for serial connections between two Cisco routers?
HDLC
When must a router serial interface be configured with the clock rate command?
When the interface is functioning as a DCE device
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.
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.
Which three encapsulation types can be set on serial interface by the administrator who is using SDM Express?
1. Frame Relay 2. HDLC 3. PPP
Which important piece of troubleshooting information can be discovered about a serial interface using the show controllers command?
serial cable type
Identify the command that will allow the cisco ios software to return to the default lmi type on interface serial 0-1 the lmi command is already set to the lmi type defined jointly by cisco and three?
Router(config-if)#no frame-relay lmi-type cisco
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.
