Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) is a protocol for remotely managing and monitoring
network devices. Network administrators can use the SNMP architecture to manage nodes, including
servers, workstations, routers, switches, hubs, and other equipment on an IP network, manage
network performance, find and solve network problems, and plan for network growth.
The IX40 device supports both SNMPv3 and SNMPv2c in read-only mode. Both are disabled by default.
SNMPv1 is not supported.
SNMP Security
By default, the IX40 device automatically blocks SNMP packets from being received over WAN and LAN
interfaces. As a result, if you want a IX40 device to receive SNMP packets, you must configure the
SNMP access control list to allow the device to receive the packets. See
Management Protocol
Standard and custom Management Information Bases (MIB)
The standard MIB defines the properties and access permissions for various managed objects so that
you can query standard information about a device, like system contact or system location via SNMP
monitoring. The custom MIB defines the unique properties and access permissions not found in the
standard MIB. To view the MIB list, see
Dynamic SNMP
To expose a specific device property for SNMP monitoring that is not included in the standard MIB -
properties like serial number, system firmware version, hardware model name, and dynamic properties
- you can query the runtime database for the property value and then add a Dynamic SNMP. The
device property is added to the custom MIB.
