Chapter 8  – SNMP Configuration 
8.1   Enabling SNMP settings 
RamSans support the Simple Network Management Protocol (SNMP), 
which is the dominant network management protocol.  The industry has 
accepted this protocol due to its relative simplicity.  The SNMP standards 
provide a framework for the definition of management information along 
with a protocol for the exchange of that information.  The RamSan-3xx 
Series is compatible with SNMP V2c.   
 
The SNMP protocol requires a “manager,” which is network management 
software that you supply, and an “agent,” which is the RamSan or other 
SNMP compatible network device.  Both the manager (via polling) and the 
agent (via a trap) can initiate management information exchanges. 
 
The RamSan allows the administrator to enable or disable the SNMP 
functionality.  For more information regarding these settings, see Section 
4.1.5 - Enable/disable SNMP
 
8.1.1  Setting SNMP community strings 
 
The SNMP community string is like a user id or password that allows 
access to the RamSan’s statistics.  The RamSan sends the community 
string along with all SNMP requests.  If the community string is correct, 
the device responds with the requested information.  If the community 
string is incorrect, the device simply discards the request and does not 
respond. 
 
There are two community strings for the RamSan: 
•  The SNMP Read-only community string enables a remote device to 
retrieve "read-only" information from a device.   
•  The SNMP Read-Write community string allows a remote device to 
read information from a device and to modify settings on that device.  
RamSan does not use the read-write community string, since it never 
attempts to modify any settings on its devices. 
 
The RamSan ships from the factory with a read-only community string of 
"read.”  It is standard practice for network managers to change all the 
community strings so that outsiders cannot see information about the 
internal network.
