Description: Enterasys Networks extension to the Power Ethernet MIB (RFC 3621) for PoE/PoE+ power allocation and budget management.

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 ENTERASYS-POWER-ETHERNET-EXT-MIB?

ENTERASYS-POWER-ETHERNET-EXT-MIB is an Enterasys Networks extension to the standard POWER-ETHERNET-MIB (RFC 3621), adding chassis- and slot-level power budgeting on top of the base per-port PSE/PD objects (it imports pethMainPseEntry and pethPsePortEntry directly). etsysPseChassisPowerAllocationMode chooses automatic vs. manual power-budget management, with etsysPseChassisPowerDetected/Available/Consumable/Assigned reporting the chassis power balance sheet and etsysPseChassisPowerRedundancy tracking supply redundancy. etsysPseSlotPowerAllocationTable and etsysPseModulePowerManagementTable (both keyed by entPhysicalIndex) manage per-slot power ceilings and per-module class budgets/usage, while etsysPsePortPowerManagementTable extends the per-port model with etsysPsePortPowerLimit (up to 34000 mW to support 802.3at PoE+), etsysPsePortCapability/CapabilitySelect, and etsysPsePortDetectionStatus. Three notifications - etsysPseChassisPowerRedundant/NonRedundant and etsysPsePowerSupplyModuleStatusChange - signal supply-redundancy and module health transitions. It's deployed on Enterasys (later Extreme Networks) PoE/PoE+ capable switch chassis where administrators need finer-grained power budgeting than the base PETH-MIB provides, and network teams can find the ENTERASYS-POWER-ETHERNET-EXT-MIB download when instrumenting these chassis.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-POWER-ETHERNET-EXT-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

  • Enterasys (later Extreme Networks) PoE/PoE+ capable switch chassis

Monitoring Examples

An operator checks etsysPseChassisPowerAvailable against etsysPseChassisPowerAssigned while a technician adds a new PoE+ module; if etsysPseModulePowerUsage for the new slot pushes assigned power close to the chassis's available maximum, an etsysPseChassisPowerNonRedundant trap firing shortly after would indicate the chassis has lost its power redundancy margin.

What Can Be Monitored

  • chassis power allocation mode and available/assigned power
  • per-slot power ceiling and per-module class budget/usage
  • per-port power limit (up to 802.3at PoE+ levels)
  • port power capability and detection status
  • power supply redundancy and module status change traps

How to Use in IPNetwork Monitor

Example using etsysPseChassisPowerDetected OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks) chassis, PoE/PoE+ capable (power budget management) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type etsysPseChassisPowerDetected into the Find box to locate it in the OID tree, then select it and click OK. The total power detected by the chassis from Pse Power Supply. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the reading rises well above what's normal for this port (in Watts), since a sustained increase often indicates a device drawing more current than expected. Click Finish to create the monitor; you can adjust any parameter later.
