SNMP

The Simple Network Management Protocol (SNMP) is an internet standard that allows a management station to monitor the status of a device over the network. SNMP organizes information about the FortiADC and provides a standard way to help gather that information. Using SNMP requires:

An SNMP agent running on the system to be monitored.
A Mangement information Base (MIB) database on the system to be monitored.
An SNMP management station running on the same or another system.

An SNMP agent and MIB databases are provided for SNMPv1 and SNMPv2c. If using a MIB browser, use SNMPv2c to ensure returned statistics.

A management station is not provided with FortiADC and must be obtained from a third party supplier. The management station is often used primarily to browse through the MIB tree, and so is sometimes called a MIB browser. One such management station that is available in a free personal edition is the iReasoning MIB Browser, available from www.ireasoning.com.

A MIB database is a hierarchical tree of variables whose values describe the state of the monitored device. A management station that want to browse the MIB database on a device sends a request to the SNMP agent running on the device. The agent queries the MIB database for the variables requested by the management station, and then sends a reply to the management station.

With SNMP, you can monitor the following information from the FortiADC MIBs:

Static configuration information, such as:

Device name and Model
Software version
Internal and External IP addresses and netmasks
Default gateway
Failover alias

FortiADC failover details

Sibling Name
Sibling Status (Primary or Secondary)

Dynamic configuration information, such as:

Failover Status (Primary or Secondary)
NAT enabled
L4 configuration state
L7 configuration state
Server Health check status
Email status notification
Cluster parameters (timeouts, buffers)
Server parameters FortiADC status
L4 Statistics
L7 Statistics FortiADC cluster
L4 or L7 protocol of cluster
Load balancing policy for cluster
IP address and port (or range)
Sticky time and inter cluster sticky
Cookie On or Off

By default, SNMP is a globally enabled service -- meaning that it will run on any subnet that is configured to offer the SNMP service. You must specifically enable SNMP on the subnet or subnets on which you want it to listen for SNMP MIB browser and management station connections.

MIB Compliance

EQ/OS 10 fully supports these proprietary FortiADC MIBS:

CPS-EQUALIZER-v10-MIB
CPS-REGISTRATIONS-v10-MIB

FortiADC 4.0 provides partial support for these standard MIBS:

RFC1213-MIB (RFC1213)

System	tcp: tcpInSegs, tcpOutSegs, tcpRetransSegs, tcpInErrs, tcpOutRsts; and tcpConnTable
Interfaces	udp
IP: i`pForwarding, ipDefaultTTL, ipInReceives, ipInHdrErrors, ipInAddrErrors, ipForwDatagrams, ipInUnknownProtos, ipInDiscards, ipInDelivers, ipOutRequests, ipOutDiscards, ipOutNoRoutes, ipReasmReqds, ipReasmOKs, ipReasmFails, ipFragOKs, ipFragFails, ipFragCreates; ipAddrTable and ipNetToMediaTable`	snmp
icmp	The remaining objects are not supported

HOST-RESOURCES-MIB (RFC2790)

hrSystemUptime	hrProcessorLoad
hrSystemDate	hrNetworkTable
hrStorage	The remaining objects are not supported.
hrDeviceTable
