Cisco Systems 12000/10700 V3.1.1 manual 19-3, Line Card in Mismatched State

Chapter 19 Change Management

Mismatched State

Two example scenarios during which a line card can be moved to mismatched state are described as follows:

Example 19-1 Scenario 1

Scenario 1—The mismatched state appears if you insert an incorrect line card that does not correspond with the line card type that has been pre-deployed and managed in Cisco 12000/10720 Router Manager.

This can occur during an Online Insertion removal process. For example, consider that a chassis has an 8 port fast Ethernet line card at Slot-1 and its being managed. If the 8 port fast Ethernet line card is removed from the device and a 3 port gigabit Ethernet line card is inserted, now the Cisco 12000/10720 Router Manager will force a rediscovery on the respective chassis. After the chassis rediscovery is completed the previously deployed and managed 8 port fast Ethernet line card object at Slot-1 will be moved to MisMatched State, with a major alarm raised against the line card object with the description Deployed module does not match actual module, because the newly inserted line card at slot-1 (ie.3 port gigabit Ethernet) is of different type against the originally pre-deployed and managed 8 port fast Ethernet line card. Similarly all the interface objects of the mismatched line card object will also be moved to MisMatched state.

The mismatched line card object and all its interface object icons in the viewer are hashed and also will be associated with an OSI Icon as displayed below, under the Component Managed and Physical (object’s GIFs) views.

To rectify the line card mismatch problem caused due to this scenario, either the incorrect line card can be removed from the device and the correct type of line card can be inserted at Slot-1 or if the newly inserted 3 port gigabit Ethernet line card needs to be retained in the device, then the mismatched line card object need to be decommissioned and deleted, then need to re-commission the chassis object. This will result in discovering the 3 port gigabit Ethernet line card and all its interface objects in appropriate states.
