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 PLAINTREE-SWITCH-MIB?

PLAINTREE-SWITCH-MIB is a vendor MIB for Plaintree Systems Ethernet switches, covering port configuration, the forwarding (bridge) database, and per-port traffic statistics. It exposes both hardware inventory data (product code, serial number, MAC address, place and date of manufacture) and operational configuration objects for switch ports and bridging behavior. For hardware/software status monitoring, it is notable for surfacing firmware/code version (switchCodeVersion) and providing administrative actions such as resetting the switch or erasing its SNMP configuration, which are useful for confirming device identity and current software load during audits or troubleshooting. It builds on bridge-related concepts similar to the standard BRIDGE-MIB (dot1d) given the restoreSwitchDot1dDefaults object, indicating an implied dependency on IEEE 802.1D bridging conventions. It is deployed in enterprise or campus network closets where Plaintree switches provide Ethernet connectivity. Engineers can download the PLAINTREE-SWITCH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PLAINTREE-SWITCH-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.

Monitoring Examples

An admin would poll switchBasicTable/switchBasicEntry to retrieve inventory fields like switchProductCode, switchSerialNumber, and switchMacAddress to confirm hardware identity, and check switchCodeVersion to verify the running firmware release during a compliance audit. If switchBpeEnabled unexpectedly changes state or switchCodeVersion doesn't match the expected release after a suspected reboot, that signals a configuration drift or failed firmware rollback. The performSwitchReset and eraseSwitchSnmpConfigInfo objects are administrative controls rather than monitoring points, useful for remote recovery scenarios.

Setting this variable to FALSE (0) causes the BPE to stop performing the Spanning Tree Protocol. The value of this variable when the switch starts operating is 1.
INT eraseSwitchSnmpConfigInfo	1.3.6.1.4.1.295.3.2.1.1.1.8	INTEGER	read-write	Setting this variable to TRUE (1) causes the switch to erase its SNMP configuration information both from memory and from permanent store.

INT switchPortHighSensitivity	1.3.6.1.4.1.295.3.2.1.2.1.7	INTEGER	read-write	This variable is only valid if the port is an Ethernet port. If this variable is set to TRUE (1), the receiver of the Ethernet NIC controlling the port is set to high sensitivity. If the variable is set to 0, the port is set to normal sensitivity. If the ports on both ends of the 10BaseT link are set to high sensitivity, the maximum permissable length of the link is increased from 100 meters to 120 meters. Caution: a high sensitivity receiver may be overdriven by transmitters closer than 100 meters. This variable is 0 when the switch is powered up for the first time.

Setting this variable to TRUE (1) causes the agent to restore the default MIB values given in the ANSI X3T9.5/84-49 Rev 7.2 specification. This resets all writable FDDI MIB variables. Setting the variable to any other value has no effect. This variable will always return 0 when read.
