Description: Enterasys Networks MIB for configuring and monitoring high-availability in-service software upgrade (ISSU) operations.

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-HIGH-AVAILABILITY-MIB?

ENTERASYS-HIGH-AVAILABILITY-MIB is a vendor-specific Enterasys Networks MIB for configuring and monitoring high-availability In-Service Software Upgrade (ISSU) operations on stackable/modular switches. It exposes upgrade status, original and target software images, and per-slot lists tracking pending, in-progress, upgraded, and error states, along with start time, duration, and inter-group upgrade delay configuration. This is a strong hardware/software status MIB, giving real-time visibility into a live software upgrade's progress across chassis line cards or stack members, including detecting stalled or failed slots during the upgrade. As an ISSU-focused module it depends on the switch's underlying software image management and stacking/chassis architecture. It is typically deployed on Enterasys Networks modular chassis or stackable switch platforms performing minimal-downtime firmware upgrades. Network engineers evaluating or troubleshooting this functionality can download the ENTERASYS-HIGH-AVAILABILITY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-HIGH-AVAILABILITY-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 Networks modular/stackable switch chassis

Monitoring Examples

etsysHauStatsStatus reports the overall state of an in-progress ISSU operation, while etsysHauStatsOriginalImage and etsysHauStatsTargetImage confirm which firmware versions are involved. etsysHauStatsPendingSlotList, etsysHauStatsInProgressSlotList, etsysHauStatsUpgradedSlotList, and etsysHauStatsErrorSlotList let an admin track upgrade progress across a chassis's line cards in real time; a slot appearing in etsysHauStatsErrorSlotList alongside etsysHauStatsDuration exceeding the expected window would indicate a failed or stalled module during the software upgrade, prompting manual intervention.

What Can Be Monitored

ISSU/HA upgrade status
original vs target software image
per-slot upgrade progress (pending/in-progress/upgraded/error)
upgrade start time and duration
inter-group upgrade delay configuration

OIDs

OID symbolic	OID numeric	Type	Access	Description
etsysHighAvailabilityUpgradeMIB	1.3.6.1.4.1.5624.1.2.84			This MIB module defines a portion of the SNMP MIB under the Enterasys Networks enterprise OID pertaining to configuration and monitoring of high-availability upgrades.
etsysHauObjects	1.3.6.1.4.1.5624.1.2.84.1
etsysHauStats	1.3.6.1.4.1.5624.1.2.84.1.1
ETS etsysHauStatsStatus	1.3.6.1.4.1.5624.1.2.84.1.1.1	EtsysHauSystemStatus	read-only	The status of the high-availability upgrade for this managed entity.
STR etsysHauStatsOriginalImage	1.3.6.1.4.1.5624.1.2.84.1.1.2	SnmpAdminString	read-only	The release and version of firmware the managed entity is upgrading from (i.e, firmware that is running at the start of high-availability upgrade).
STR etsysHauStatsTargetImage	1.3.6.1.4.1.5624.1.2.84.1.1.3	SnmpAdminString	read-only	The release and version of firmware the managed entity is upgrading to (i.e, firmware that will be running after successful completion of high-availability upgrade).
HAU etsysHauStatsPendingSlotList	1.3.6.1.4.1.5624.1.2.84.1.1.4	HauSlotList	read-only	Set of slots which have yet to be upgraded.
HAU etsysHauStatsInProgressSlotList	1.3.6.1.4.1.5624.1.2.84.1.1.5	HauSlotList	read-only	Set of slots which are currently being upgraded.
HAU etsysHauStatsUpgradedSlotList	1.3.6.1.4.1.5624.1.2.84.1.1.6	HauSlotList	read-only	Set of slots which have been upgraded.
HAU etsysHauStatsErrorSlotList	1.3.6.1.4.1.5624.1.2.84.1.1.7	HauSlotList	read-only	Set of slots which have failed to be upgraded.
DAT etsysHauStatsStartTime	1.3.6.1.4.1.5624.1.2.84.1.1.8	DateAndTime	read-only	The date and time when the most recent high-availability upgrade was started.
NUM etsysHauStatsDuration	1.3.6.1.4.1.5624.1.2.84.1.1.9	TimeInterval	read-only	The duration of the most recent current high-availability upgrade, in centiseconds.
etsysHauSystem	1.3.6.1.4.1.5624.1.2.84.1.2
U32 etsysHauSystemInterGroupDelay	1.3.6.1.4.1.5624.1.2.84.1.2.1	Unsigned32	read-write	The duration, in seconds, the high-availability upgrade process will delay between the successful upgrade of one upgrade group and the start of the next upgrade group's upgrade. When an upgrade group is upgraded, all modules which are a member of the group are reset. If these resets cause instability in higher-layer networking protocols, then this delay may help those protocols stabilize during the course of the high-availability upgrade. Note that this delay will increase the overall length of the high-availability upgrade process.
ETS etsysHauSystemHauMode	1.3.6.1.4.1.5624.1.2.84.1.2.2	EtsysHauMode	read-write	The desired mode of operation to attempt to use when performing a reset. When set to hauNever(1) a high-availability upgrade will never be performed. Instead a standard upgrade will be performed. When set to hauIfPossible(2) a high-availability upgrade will be performed if the current and target images are compatible, otherwise a standard upgrade will be performed. When set to hauAlways(3) a high-availability upgrade will always be performed. If the current and target images are incompatible then no upgrade will occur.
etsysHauModule	1.3.6.1.4.1.5624.1.2.84.1.3
etsysHauModuleTable	1.3.6.1.4.1.5624.1.2.84.1.3.1		not-accessible	A table of high-availability properties per module.
etsysHauModuleEntry	1.3.6.1.4.1.5624.1.2.84.1.3.1.1		not-accessible	An entry containing high-availability properties per module.
HAU etsysHauModuleSlot	1.3.6.1.4.1.5624.1.2.84.1.3.1.1.1	HauSlot	not-accessible	Logical slot for a given module.
PHY etsysHauModuleEntRef	1.3.6.1.4.1.5624.1.2.84.1.3.1.1.2	PhysicalIndex	read-only	Entity Physical Index which corresponds to this slot.
U32 etsysHauModuleGroupId	1.3.6.1.4.1.5624.1.2.84.1.3.1.1.3	Unsigned32	read-write	This object is a user-assigned value used to assign individual modules to a High-Availability Upgrade Group. All slots within an upgrade group will be upgraded simultaneously. The purpose of assigning multiple slots to the same upgrade group is to reduce the overall time it takes to perform an HA upgrade. By default, each module is assigned to its own upgrade group, with GroupId equal to the module's HAU Slot. Although this default configuration is completely valid, it may not be optimal for situations where a timely HA upgrade is desirable. The network architecture, specifically LAGs, must be taken into consideration when assigning slots to an upgrade group. LAGs which span multiple modules should not have all of their modules placed into the same upgrade group, as this would defeat the LAG's inherent redundancy. IMPORTANT: If a LAG is to remain available during a High-Availability Upgrade, then it must comprised of multiple single-port links which reside on separate modules. Furthermore, at least two of those modules must reside in separate upgrade groups.
etsysHauConformance	1.3.6.1.4.1.5624.1.2.84.2
etsysHauGroups	1.3.6.1.4.1.5624.1.2.84.2.1

etsysHauModuleGroup	1.3.6.1.4.1.5624.1.2.84.2.1.2			The module specific configuration group for all devices supporting High-Availability Upgrade.
etsysHauCompliances	1.3.6.1.4.1.5624.1.2.84.2.2
