Enabling or disabling CDP
To discover and send advertisements to CDP-compliant neighboring devices, CDP must be enabled on each node of the cluster. By default, CDP is enabled on all cluster ports of a node and disabled on all non-cluster ports of a node.
About this task
The cdpd.enable option controls whether CDP is enabled or disabled on the ports of a node:
- on enables CDP on non-cluster ports.
- off disables CDP on non-cluster ports; you cannot disable CDP on cluster ports.
When CDP is disabled on a port that is connected to a CDP-compliant device, network traffic might not be optimized.
- Display the current CDP setting for a node, or for all nodes in a cluster:
