brcdStackISSUGlobalUpgradeOption

1.3.6.1.4.1.1991.1.1.3.41.1.1

Syntax: Integer

Read-write

Configures the system upgrade option to initiate stack upgrade process using primary or secondary image.

The SET operation is allowed only on the active unit in stacking system or IEEE 802.1BR (SPX) system.

• none (0)- reserve state. The default is none state.
• primary(1) - system upgrade process using primary image
• secondary(2) - system upgrade process using secondary image
• primaryOnErrorReloadPrimary(3) - system upgrade process using primary image, reloads from primary if upgrade fails.
• primaryOnErrorReloadSecondary(4) - system upgrade process using primary image, reloads from secondary if upgrade fails.
• secondaryOnErrorReloadPrimary(5) - system upgrade process using secondary image, reloads from primary if upgrade fails.
• secondaryOnErrorReloadSecondary(6) - system upgrade process using secondary image, reloads from secondary if upgrade fails.
• abort(7) - aborts upgrade process. A reload is required to bring the stack back to the working condition after abort is issued.

brcdStackISSUGlobalUpgradeStatus

1.3.6.1.4.1.1991.1.1.3.41.1.2

Syntax: Integer

Read-only

The state of upgrade process for a stacking or SPX system. The default state is in notUpgrading state. The return values are:

notUpgrading (0),

unitToBeUpgraded (1),

unitJoin (2),

unitVersionSync (3),

unitReady (4),

peUnitJoin (5),

peUnitVersionSync (6),

peUnitReady (7),

standbyAssignment (8),

standbySyncCompleted (9),

stackSwitchover (10),

stackSwitchoverCompleted (11),

upgradeAbort(12),

waitingForReload (13)

brcdStackISSUGlobalUpgradeSystemReady

1.3.6.1.4.1.1991.1.1.3.41.1.3

Syntax: Integer

Read-only

The per-upgrade state of a stacking or SPX system. The state of the upgrade process is:

• notReadyUpgrade(0)
• ready(1)

The system must be in ready state before the upgrade process starts. It checks the following aspects:

• Topology is Ring - Yes
• Standby Present - Yes
• Standby ready for upgrade - Yes
• Flash use in progress - No
• Secure Setup in progress - No
• ISSU in progress - No
• Election in progress - No
• All units in ready state - Yes
• Primary Image is upgrade compatible - Yes
• Secondary Image is upgrade compatible - Yes
• Startup config and Running Config Same - Yes
• Config mode conflict - No

The system shows status as system ready for ISSU, if all conditions are met and at least one flash partition, primary or secondary, has a compatible image.

brcdStackISSUGlobalUpgradeError

1.3.6.1.4.1.1991.1.1.3.41.1.4

Syntax: DisplayString

Read-only

The error message occurs during the system upgrade process on a stacking or SPX system.

Before or after ISSU process, the OID will return the value as "System is not in Stack ISSU mode". During ISSU, the value is null string, which means system has no error or is in no-upgrade state.
