 VLAN Cross Connect
 ==================
 
-VLAN cross connect creates a L2 bridge between two given ports on the same
-device.  Once configured, every packets arriving at one of the port with
-specific VLAN tag will be sent to another port directly.  Current
+VLAN cross connect creates a L2 bridge between two given endpoints on the same
+device.  Once configured, every packets arriving at one of the endpoints with
+specific VLAN tag will be sent to another endpoint directly.  Current
 implementation only matches on the outermost VLAN tag. If the packet is double
 tagged, the S-tag will be matched and both the S-tag and C-tag will be
 persisted.
 
+.. note::
+    An endpoint could be a physical port number or a logical port load balancer ID.
+    See examples below.
+
 VLAN cross connect only works on the same device.  If you are looking for
 transporting L2 traffic across devices, please refer to :doc:`pseoduwire
