CDP

Cisco Discovery Protocol (CDP) configuration manages global CDP behavior on NX-OS devices. CDP is enabled by default; these settings tune CDP timer interval and holdtime, protocol version selection (v1 or v2), device ID format for CDP advertisements, and PnP startup VLAN assignment.

Examples

Example 1: Basic CDP with custom timers and advertise version

nxos:
  devices:
    - name: LEAF1
      configuration:
        cdp:
          timer: 30
          holdtime: 120
          advertise: v2

Example 2: CDP with serial-number device ID for inventory tracking

nxos:
  devices:
    - name: LEAF1
      configuration:
        cdp:
          timer: 60
          holdtime: 180
          advertise: v2
          format_device_id: serial-number

Example 3: CDP with PnP startup VLAN for zero-touch provisioning

nxos:
  devices:
    - name: LEAF1
      configuration:
        cdp:
          timer: 60
          holdtime: 180
          advertise: v2
          format_device_id: system-name
          pnp_startup_vlan: 100
