CDP Commands Cheat Sheet
| Command | Description |
|---|---|
| Router#clear cdp table | Clear CDP tables data |
| Router(config)#cdp run | Enable CDP globally |
| Router(config)#no cdp run | Disable CDP globally |
| Router(config)#cdp holdtime x | Change hold down time of CDP |
What is the command used to allow the CDP on the port of the device?
CDP can be disabled for all the interfaces on the device with the no cdp run command in the global configuration mode. Use the show cdp interface command to display the interfaces that are CDP-enabled on a device. The status of each interface is also displayed.
What is the command to determine which CDP enabled devices are directly connected to Gateway?
a. On router Gateway, enter the show cdp command in the privileged EXEC mode to verify that CDP is currently enabled on router Gateway.
What is CDP and LLDP?
LLDP (Link Layer Discovery Protocol) and CDP (Cisco Discovery Protocol) are link layer protocols for directly-connected LLDP and CDP-capable neighbors to advertise themselves and their capabilities.
What is CDP configuration?
CDP is a protocol that runs over Layer 2 (the data link layer) on all Cisco routers, bridges, access servers, and switches. CDP allows network management applications to discover Cisco devices that are neighbors of already known devices, in particular, neighbors running lower-layer, transparent protocols.
How do I enable CDP neighbors on Cisco router?
To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable command in interface configuration mode. To disable CDP on an interface, use the no form of this command. This command has no arguments or keywords. Enabled at the global level and on all the supported interfaces.
What command would you use to verify whether CDP is enabled or disabled in a Cisco device?
You can verify whether CDP is enabled or disabled on your Cisco device using the show cdp neighbors command.
How do I enable Cisco CDP?
What is LLDP in Cisco?
LLDP is a neighbor discovery protocol that is used for network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other.
Does LLDP use same commands as CDP?
LLDP configuration To display the neighbors’ information the same procedure used in CDP is applied but we use the command show lldp neighbors .
How do I enable CDP on my Cisco device?
How do I enable CDP on a Cisco router?
CDP Command Reference. This chapter describes commands used to monitor the router and network using Cisco Discovery Protocol (CDP). To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable command in interface configuration mode. To disable CDP on an interface, use the no form of this command.
How do I monitor the router and network using Cisco Discovery Protocol?
This chapter describes commands used to monitor the router and network using Cisco Discovery Protocol (CDP). To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable command in interface configuration mode.
Why does the CDP command affect on-Demand Routing (ODR)?
Because on-demand routing (ODR) uses Cisco Discovery Protocol, the cdp enable, cdp timer, and cdp run commands affect the operation of the router odr global configuration command. For more information about the router odr command, see the Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols document.
Why does the show running-config command list no CDP run when disabled globally?
The show running-config command lists no cdp run when Cisco Discovery Protocol is disabled globally, which is not the default behavior. As a result of changes made for the Cisco 10000 platform, the show running-config command will list the cdp run command when Cisco Discovery Protocol is enabled globally.
