+module: nxos_udld

+short_description: Manages UDLD global configuration params.
+description:
+    - Manages UDLD global configuration params.
+extends_documentation_fragment: nxos
+author:
+    - Jason Edelman (@jedelman8)
+notes:
+    - When C(state=absent), it unconfigures existing setings C(msg_time) and set it
+      to its default value of 15.  It is cleaner to always use C(state=present).
+    - Module will fail if the udld feature has not been previously enabled.
+options:
+    aggressive:
+        description:
+            - Toggles aggressive mode.
