Accessing the various SNMP functions 

Once the MIB file has been loaded to an SNMP server (via a front-end software typically called a MIB Browser) we can 
read in status information and set up specific functions otherwise not available via the 

Web interface

. 

The MIB Browser (or equivalent front-end SNMP software) will display the Magma chassis MIB contents in an explorer-like, 
Tree interface.      A snapshot from the MIB Browser by 

iReasoning 

is shown below: 

 

Under the MIB Tree, the Magma Chassis will have status information that can be read by expanding the respective 
folders. This information is also available in the Web interface mentioned previously.                         In addition, if we 
expand the 

sendAction

 folder (as shown above) we gain access to “writable” functions that essentially allow us to 

remote-control the chassis. 

 

Remote Chassis Reset (turnPowerOffOn) 

 

This function allows us to remotely turn the chassis off and on.  

Right-click on it, and an options menu will appear. Select the “
