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-325 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.
