 SNMP::Info - Perl5 OO Interface to Network Devices and SNMP MIBs
 ChangeLog $Id$
 
+version 0.4 (04/29/03)
+    * BIG CHANGE ! Internal Data structure has changed.  
+    * Added clear_cache() method
+    * Added NO_SUCH support for snmpget (TABLE) calls to get SNMP MIB II data 
+      from SNMP Version 1 devices.
+    * Methods load_all() and all() have changed their return value. Sorry but the API had to change.
+    * New object methods snmp_comm(), snmp_ver(), store(), class(), nosuch() to make it more OO happy.
+    * Globals are now cached
+    * Added new argument 'AutoSpecify' to new() to auto-connect with subclass 
+      detected in device_type()
+    * New method specify() returns a new subclass object
+    * Subclasses are automatically loaded when specify or autospecify is used!
+    * Added methods for Interface statistics (ifInOctets ...)
+    * Added methods for Memory and CPU statistics 
+    * Added SNMP::Info::Entity, moved out of L2-HP
+    * Added SNMP::Info::Layer2::Aironet
+
 version 0.3 (03/06/03)
     * Fixed HP model() warning
     * Added error checking for responses of NOSUCHOBJECT and NOSUCHINSTANCE in _global

+
+SNMP::Info subclass to provide information for Cisco Catalyst switches running CatOS.
+
+This subclass is not for all devices that have the name Catalyst.  Note that some Catalyst
+switches run IOS, like the 2900 and 3550 families.  Cisco Catalyst 1900 switches use their
+own MIB and have a separate subclass.  Use the method above to have SNMP::Info determine the
+appropriate subclass before using this class directly.
+
+Note:  Some older Catalyst switches will only talk SNMP version 1.  Some newer ones will not
+return all their data if connected via Version 1.
+
+For speed or debugging purposes you can call the subclass directly, but not after determining
+a more specific class using the method above.

+
+SNMP::Info::MAU is a sublcass of SNMP::Info that supplies access to the
+MAU-MIB (RFC2668). This MIB is sometimes implemented on Layer 2 network devices like HP Switches.
+MAU = Media Access Unit.
+
+The MAU table contains link and duplex info for the port itself and the device
+connected to that port.
+
+Normally you use or create a subclass of SNMP::Info that inherits this one.  Do not use directly.
+
+For debugging purposes call the class directly as you would SNMP::Info
