+short_description: Manage port lists on BIG-IP AFM
+description:
+  - Manages the AFM port lists on a BIG-IP. This module can be used to add
+    and remove port list entries.
+version_added: "2.5"
+options:
+  name:
+    description:
+      - Specifies the name of the port list.
+    required: True
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+    version_added: 2.5
+  description:
+    description:
+      - Description of the port list
+  ports:
+    description:
+      - Simple list of port values to add to the list
+  port_ranges:
+    description:
+      - A list of port ranges where the range starts with a port number, is followed
+        by a dash (-) and then a second number.
+      - If the first number is greater than the second number, the numbers will be
+        reversed so-as to be properly formatted. ie, 90-78 would become 78-90.
+  port_lists:
+    description:
+      - Simple list of existing port lists to add to this list. Port lists can be
+        specified in either their fully qualified name (/Common/foo) or their short
+        name (foo). If a short name is used, the C(partition) argument will automatically
+        be prepended to the short name.
+notes:
+  - Requires the f5-sdk Python package on the host. This is as easy as pip
+    install f5-sdk.
+requirements:
+  - f5-sdk >= 3.0.4
