 | 
						|
 | 
						|
Provides abstraction to the configuration information obtainable from an 
 | 
						|
Extreme device through SNMP. 
 | 
						|
 | 
						|
For speed or debugging purposes you can call the subclass directly, but not
 | 
						|
after determining a more specific class using the method above.

  Example:
 |
