+# Netgear Switch Discovery Protocol Input Plugin
+
+This plugin gathers metrics from devices via the
+[Netgear Switch Discovery Protocol][nsdp] for all available switches and ports.
+
+⭐ Telegraf v1.34.0
+🏷️ network
+💻 all

+[nsdp]: https://en.wikipedia.org/wiki/Netgear_Switch_Discovery_Protocol
+
+## Global configuration options <!-- @/docs/includes/plugin_config.md -->
+
+In addition to the plugin-specific configuration settings, plugins support
+additional global and plugin configuration settings. These settings are used to
+modify metrics, tags, and field or create aliases and configure ordering, etc.
+See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
+
+[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
+
+## Configuration
+
+```toml @sample.conf
+# Gather Netgear Switch Discovery Protocol status
+[[inputs.nsdp]]
+  ## The target address to use for status gathering. Either Broadcast (default)
+  ## or the address of a single well-known device.
+  # address = "255.255.255.255:63322"
+
+  ## The maximum number of device responses to wait for. 0 means no limit.
+  ## NSDP works asynchronously. Without a limit (0) the plugin always waits
+  ## the amount given in timeout for possible responses. By setting this
+  ## option to the known number of devices, the plugin completes
+  ## processing as soon as the last device has answered.
+  # device_limit = 0
+
+  ## The maximum duration to wait for device responses.
+  # timeout = "2s"
+```
+
