+    DESCRIPTION
+        "A MIB module for extending the IF-MIB (RFC2863)
+        to add objects which provide additional information
+        about interfaces not available in other MIBS.
+        This MIB replaces the OLD-CISCO-INTERFACES-MIB.
+
+        GLOSSARY :
+
+        Virtual Switch - A physical switch partitioned into 
+                multiple logical switches.
+
+        Interface Sharing - An interface can be shared among 
+                multiple virtual switches.
+
+        Speed Group - An interface is capable of operating in any one of
+        the speed range depending on the capability of the hardware.
+
+        Virtual Link (VL) - Virtual Link is a logical connectivity 
+            between two end points. A physical interface can 
+            have multiple Virtual Links.
+
+        No Drop Virtual Link - According to 802.3 standard, 
+            No drop specifies lossless service on a virtual link.
+
+        Drop Virtual Link - According to 802.3 standard,
+            Traffic drop may occur on this virtual Link."
