+### <a name="api-route-29">Function: `get_port_stack`</a> [`top`](#top)
+
+Get a list of port mappings for a device.  This is useful for showing physical ports that are in a virtual port-channel.
+
+Route: /api/v0/devices/:hostname/port_stack
+
+- hostname can be either the device hostname or id
+
+Input:
+
+ - valid_mappings: Filter the result by only showing valid mappings ("0" values not shown).
