+Predict network adapter name before deployment
+==============================================
+
+
+
+Traditionally, network interfaces in Linux are enumerated as eth[0123…], but these names do not necessarily correspond to actual labels on the chassis. customer need a methods to get consistent and predictable network device name before provision or network configuration. xCAT provide a tool ``getadapters`` to help customer to resolve this problem.
+
+
+**[Note]** : This feature needs to restart your target sever which you want to obtain network adapter from.
+
+How to use get adapters
+-----------------------
+
+
+Using below command to obtain the network adapters information ::
+ 
+    getadapters <noderange>
+
+Then will get output like below ::
+
+
+    The whole scan result:

+Every node gets a separate section to display its all network adapters information, every network adapter owns single line which start as node name and followed by index and other information.
+
+xCAT try its best to collect more information for each network adapter, but can’t guarantee collect same much information for every one. If a network adapter can be derived by xcat genesis, this adapter will have a predictable name, if it can’t be, it only has the information xcat can obtain.
+    
+below are the possible information:
+
+* **hitn**: the consistent name which can be used in ``confignic`` derectly in operating system which follow the same naming scheme with rhels7. (``confignic`` doesn’t need to do more work)
+
+* **pci**: the pci location
+
+* **mac**: the MAC address
+
+* **prdn**: All the names which satisfy predictable network device naming scheme, if customer needs to customize their network adapter name, they can choose one of them. (``confignic`` needs to do more work to support this. if customer want to use their own name, xcat should offer a interface to get customer’s input and change this column) 
+
+* **vnd**:  the vender of network device
+
+* **mod**:  the modle of network device
