Description: Manages ZyXEL system administration settings including login, firmware upgrade, and configuration backup.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ZYXEL-SYSTEM-MGMT-MIB?

ZYXEL-SYSTEM-MGMT-MIB is a ZyXEL Communications enterprise MIB covering core system administration on ZyXEL switches, including configuration persistence, firmware/image selection, reboot control, and TFTP-based backup and restore. Objects such as zySysMgmtConfigSave/zySysMgmtBootupConfig and zySysMgmtBootupImage select which of two configuration files or firmware images is active or will be used at next boot, while zySysMgmtReboot and zySysMgmtDefaultConfig trigger a reboot or a full factory-default reset from SNMP. The zyxelSysMgmtTftpServiceSetup subtree drives remote configuration management, letting an operator set a TFTP server IP and filename and then trigger a backupConfig/restoreConfig/mergeConfig action via zySysMgmtTftpAction, tracked through zySysMgmtTftpActionStatus. Health visibility comes from zySysMgmtSysStatus, a BITS object flagging system alarm, temperature, fan RPM, and voltage-range errors, plus zySysMgmtCPUUsage for a CPU-load snapshot, and three notifications (zySysMgmtUncontrolledSystemReset, zySysMgmtControlledSystemReset, zySysMgmtBootImageInconsistence) flag unexpected resets or firmware/image mismatches. It depends on the ZYXEL-ES-SMI enterprise tree for OID placement and is deployed on ZyXEL managed switches, and administrators can download the ZYXEL-SYSTEM-MGMT-MIB file to automate configuration backup and monitor system health.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-SYSTEM-MGMT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

ZyXEL managed switches (ES/GS series)

Monitoring Examples

An operator polls zySysMgmtSysStatus and zySysMgmtCPUUsage on a schedule and subscribes to zySysMgmtUncontrolledSystemReset; a sysTemperatureError or sysFanRPMError bit set alongside an uncontrolled-reset trap would indicate the switch rebooted due to an overheating or cooling-related hardware fault rather than an administrative command.

What Can Be Monitored

system alarm/temperature/fan/voltage status bits
CPU utilization snapshot
active/bootup configuration and firmware image selection
TFTP backup/restore/merge action status
controlled vs. uncontrolled system reset events
boot-image consistency

OIDs

OID symbolic	OID numeric	Type	Access	Description
zyxelManagement	1.3.6.1.4.1.890.1.15.3.49			The subtree for management
zyxelSysMgmt	1.3.6.1.4.1.890.1.15.3.49.1
INT zySysMgmtConfigSave	1.3.6.1.4.1.890.1.15.3.49.1.1	INTEGER	read-write	According setting value, running-config will be written to the assigned configuration file. If not, running-config will be written to the booting configuration file. Note: This action can access all configuration includes user account and AA configuration.
INT zySysMgmtBootupConfig	1.3.6.1.4.1.890.1.15.3.49.1.2	INTEGER	read-write	The setting value (read index) will be written into non-volatile memory. While rebooting, the variable write index is equal to read index initially.
INT zySysMgmtReboot	1.3.6.1.4.1.890.1.15.3.49.1.3	INTEGER	read-write	Reboot switch from SNMP. 1:Reboot, 0:Nothing
INT zySysMgmtDefaultConfig	1.3.6.1.4.1.890.1.15.3.49.1.4	INTEGER	read-write	Erase running config and reset to default. Note: This action can access all configuration includes user account and AA configuration.
INT zySysMgmtLastActionStatus	1.3.6.1.4.1.890.1.15.3.49.1.5	INTEGER	read-only	Display status of last managment action.
BIT zySysMgmtSysStatus	1.3.6.1.4.1.890.1.15.3.49.1.6	Bits	read-only	This variable indicates the status of the system. The zyxelSysMgmtSysStatus is a bit map represented a sum, therefore, it can represent multiple defects simultaneously. The sysNoDefect should be set if and only if no other flag is set. The various bit positions are: 0 sysAlarmDetected 1 sysTemperatureError 2 sysFanRPMError 3 sysVoltageRangeError 4 sysNoDefect
INT zySysMgmtCPUUsage	1.3.6.1.4.1.890.1.15.3.49.1.7	INTEGER	read-only	Show device CPU load in %, it's the snapshot of CPU load when getting the values.
INT zySysMgmtBootupImage	1.3.6.1.4.1.890.1.15.3.49.1.8	INTEGER	read-write	The setting value (read index) will be written into non-volatile memory. When rebooting, the selected image will be used.
INT zySysMgmtCounterReset	1.3.6.1.4.1.890.1.15.3.49.1.9	INTEGER	read-write	Reset all port counters.
