What is the default value of CDP timer command?

The default value of the CDP timer command is 60 seconds.

What is CDP?

CDP stands for Cisco Discovery Protocol. It is a proprietary network protocol developed by Cisco Systems that runs on most Cisco equipment.

What is the purpose of CDP?

The primary purpose of CDP is to collect and share information about directly connected Cisco devices.

What does the CDP timer command do?

The CDP timer command allows users to modify the timer values for various CDP messages exchanged between devices.

How does the CDP timer command work?

The CDP timer command is used to adjust the time interval between CDP messages. This interval determines how often CDP information is sent and received.

What are the timer values that can be adjusted using the CDP timer command?

The CDP timer command allows users to modify four timer values: holdtime, rate-limit, log, and timer.

What is the holdtime value in the CDP timer command?

The holdtime value represents the time interval during which a receiving device maintains information received via CDP before discarding it.

What is the rate-limit value in the CDP timer command?

The rate-limit value is used to specify the maximum number of CDP packets transmitted per second.

What is the log value in the CDP timer command?

The log value is used to specify the logging interval in minutes. This determines how often CDP status messages are generated in the system logging file.

What is the timer value in the CDP timer command?

The timer value is used to modify the default timer value for all CDP timer-based messages.

Can the CDP timer command be disabled?

No, the CDP timer command cannot be disabled. However, its timer values can be adjusted or set to their default values.

How can the CDP timer values be modified?

The CDP timer values can be modified using the Cisco IOS command-line interface (CLI) by accessing the device’s configuration mode.

What happens if the CDP timer values are modified?

Modifying the CDP timer values may impact the frequency and timing of CDP messages exchanged between devices.

Are the CDP timer values persistent across device reboots?

Yes, the CDP timer values are persistent. They will remain configured even after a device reboot unless explicitly changed or reset to their default values.

What are the benefits of adjusting CDP timer values?

Adjusting CDP timer values can help optimize network performance, reduce unnecessary traffic, and control the frequency of CDP messages in the network.

In conclusion, the default value of the CDP timer command is 60 seconds. This command allows users to modify various timer values related to CDP messages exchanged between Cisco devices. Adjusting these values can help optimize network performance and control the frequency of CDP messages.
