SNMP

The Simple Network Management Protocol (SNMP) is used by network management systems to monitor network-attached devices such as routers, servers, and switches. SNMP allows you to make quick queries about the condition of each monitored network device. You can configure Sophos UTM to reply to SNMP queries or to send SNMP traps to SNMP management tools. The former is achieved with so-called management information bases (MIBs). An MIB specifies what information can be queried for which network device. Sophos UTM supports SNMP version 2 and 3 and the following MIBs:

• DISMAN-EVENT-MIB: Event Management Information Base
• HOST-RESOURCES-MIB: Host Resources Management Information Base
• IF-MIB: Interfaces Group Management Information Base
• IP-FORWARD-MIB: IP Forwarding Table Management Information Base
• IP-MIB: Management Information Base for the Internet Protocol (IP)
• NOTIFICATION-LOG-MIB: Notification Log Management Information Base
• RFC1213-MIB: Management Information Base for Network Management of TCP/IP-based Internet: MIB II
• SNMPv2-MIB: Management Information Base for the Simple Network Management Protocol (SNMP)
• TCP-MIB: Management Information Base for the Transmission Control Protocol (TCP)
• UDP-MIB: Management Information Base for the User Datagram Protocol (UDP)

In order to get Sophos UTM system information, an SNMP manager must be used that has at least the RFC1213-MIB (MIB II) compiled into it.
