Usage Guidelines

Usage Scenario

To check the topology information collected using NTDP, run the display ntdp device-list command. The topology information can be displayed only after ntdp explore command is run in the user view to enable the switch to periodically collect the topology information.

When NTDP is not enabled on interfaces of the switch, only information about the switch itself is collected using NTDP.

Prerequisites

NTDP has been globally enabled on the switch.

Example

# Display brief switch information collected using NTDP.
