Cisco Systems 12000/10700 V3.1.1 Discovery Lost Comms, Mismatched, Transient Object States

Chapter 2 Concepts

Cisco 12000/10720 Router Manager Object States

Heartbeat polling is performed on an object in the performance logging on state. If the object moves into the errored state, it is returned to the performance logging on state when the error is rectified. For example, if a line card is in the performance logging on state and it goes down in the device, the EM moves the line card into the errored state. When heartbeat polling finds that the line card is operational, the EM restores the line card to the performance logging on state.

Lost Comms

The lost comms (lost communications) state indicates that the object is not contactable. Cisco 12000/10720 Router Manager can apply this state to a chassis, module, or interface. During this state, heartbeat polling is performed on the object. When the object becomes contactable again, it moves out of the lost comms state.

Discovery Lost Comms

The discovery lost comms state is quite similar to the lost comms state; however, this state only occurs during subchassis discovery. For example, if you commission a chassis (which begins the process of subchassis discovery), and if a pre-deployed line card is not present then, the line card is moved into the discovery lost comms state. When the linecard is re-inserted in the device, subchassis discovery is resumed, and the object moves out of the discovery lost comms state.

Mismatched

The mismatched state occurs when a mismatch is found between what is in the hardware and what is deployed in Cisco 12000/10720 Router Manager. For example, say you are expecting an ATM OC-3 line card. So you predeploy and perform offline configuration in Cisco 12000/10720 Router Manager to prepare for that type of line card. Now, when the line card becomes available and is placed into the chassis, it is not an ATM OC-3 line card, but a POS OC-3 line card. So when Cisco 12000/10720 Router Manager detects the new line card, it finds a mismatch. The line card gets placed into the mismatch state, and a major alarm is raised against the line card.

Transient Object States

Certain states in Cisco 12000/10720 Router Manager are temporary or transient, that is, they exist only for a short time while a process is being performed. The following states are transient:

•Download—Temporary state that is assigned to objects in Cisco 12000/10720 Router Manager when an Cisco IOS Download is being performed.

•Discovery—Temporary state that is assigned to objects in Cisco 12000/10720 Router Manager during subchassis discovery. Objects are being discovered at this stage.

•Synchronization—This temporary state is applicable only for chassis. During this state, the EM synchronizes with its ATM connection information with the device.
