C12k/10720M Objects and Interfaces
C12k/10720M manages both physical and logical objects, as follows:
•
Physical—Represents tangible components and devices such as the chassis (hardware frame), line cards, and interfaces
•
Logical—Represents intangible, more abstract features, such as ATM connections, Layer 3 Quality of Service (QoS) objects and VLAN sub-interfaces
Fault, Configuration, Accounting and Performance (FCAP) windows are accessible on both physical and logical EM objects, in the form of FCAP menu options that appear when you right-click on any object in C12k/10720M. FCAP functionality provides a complete management interface to the features of the Cisco 12000 series and Cisco 10720 internet router.

Line Cards—There are various types of line cards within a chassis (for example, ATM, Ethernet, SRP, POS, E3, DS3 and Modular Ethernet). Each of these line cards holds a given number of physical interfaces (ports).
|
Configuration Fault Management Inventory
|
Physical Interfaces—Each line card has at least one, if not multiple, physical interfaces (ports). The type of physical interface is equivalent to the type of line card the interface resides on. Each physical interface can support multiple technologies (for details, refer to "Physical Interfaces and Technologies" section) The line card type determines what specific technologies are supported by an interface.

Note
The Cisco 10720 chassis does not support the Configuration Editor.
The physical objects and interfaces displayed in Table 2-1 are traced as follows:
•
The chassis contains the GRPs, supporting modules, and all line cards
•
The line cards contain the physical interfaces.
Refer to the "Views" section for further details on hierarchies within Cisco EMF and C12k/10720M.
Tip
Physical objects contained within a chassis are often referred to as subchassis objects or modules.
Cisco 12000/10700 Series Internet Router Chassis
The C12k/10720M application supports the entire range of Cisco 12000 series internet router chassis like: Cisco 12008, Cisco 12012, Cisco 12016, Cisco 12404, Cisco 12406, Cisco 12410, Cisco 12416 and the Cisco 10720 internet router chassis.
Figure 2-1 displays a Cisco 12016 internet router chassis as an example, and identifies the modules and sub-modules that you would find:
Figure 2-1 Cisco 12016 Chassis
The Cisco 12016 chassis supports the following components:
•
Power shelf and power supplies—Contains either 3 AC (shown) or 4 DC power modules
•
Upper and lower blower modules
•
Upper and lower cable management brackets
•
Upper card cage, which contains the following:
–
1 Non-configurable alarm card in far left slot
–
1 GRP in far right slot
–
Up to 7 line cards
•
Air filter door—Behind it is the switch fabric card cage, which contains the following:
–
2 CSCs (one is optional for redundancy)
–
3 SFCs
•
Lower card cage, which contains the following:
–
1 Non-configurable alarm card in far right slot
–
1 Optional GRP in far left slot
–
Up to 8 line cards
Supporting Modules
C12k/10720M supports five types of supporting modules within a Cisco 12000 series internet router chassis. Some modules only apply to certain chassis types.
•
CSC (Clock Scheduler Card)—CSCs handle requests from line cards, issue grants to access the switch fabric cards, and provide a reference clock to all the cards in the system to synchronize data transfer across the crossbar. Each chassis must have at least one CSC.
•
SFC (Switch Fabric Card)—SFCs receive the scheduling information and clocking reference from the CSC cards and perform the switching functions.
•
AC or DC Power Supply Module—Chassis can be ordered with either AC or DC power supply modules, having anywhere from one to four AC or DC-input power supplies, depending upon the specific chassis.
•
Blower Module—The Cisco 12012 and 12016 internet routers contain two blower modules, which circulate cooling air through the card cages in the chassis.
•
Fan Tray—The Cisco 12008 internet router contains a fan tray, which circulates cooling air through the card cage in the chassis.
Linecards
Refer "Manually Deploying Line Cards" section for details of all the supported technology specific linecards.
Physical Interfaces and Technologies
Physical interfaces are modeled as objects below the parent line card. Some generic properties are supported by all the interfaces. As mentioned before, the type of line card characterizes the type of physical interface; for example, an ATM line card will only support ATM interfaces. However, there can be multiple technologies supported on that physical interface. For example, ATM physical interfaces can support the following:
•
Internet Protocol (IP)
•
ATM
•
SONET
Note
C12k/10720M handles both SDH and SONET in the same manner. The Cisco 12000/10700 series internet routers support both SDH and SONET. For a comparison chart of SONET and SDH speeds, refer to "SONET/SDH Conversion Chart."
Tip
The technologies supported by an interface are exposed within FCAP-based management windows. It is important to understand the relationship of physical interfaces to technologies in order to properly manage an interface.
Table 2-2 outlines each physical interface and the technologies it supports. Also included are the different FCAP-based windows that are applicable to each physical interface and technology. For example, if you want to configure an ATM interface, look in the table under ATM, and you will notice that four technologies apply: Generic, ATM, SONET, and IP. This means that you should open the configuration windows for these four technologies and configure the fields within, in order to completely configure an ATM interface.

Logical Objects
C12k/10720M supports three logical object types:
•
Layer 3 QoS—Weighted Random Early Detection (WRED) or Committed Access Rate (CAR) objects, such as Class of Service (CoS) Queue Groups, WRED ToFab policies, CAR policies, and CAR access lists.
Note
The Cisco 10720 internet router does not support Layer 3 QoS objects.
•
ATM connections—Permanent Virtual Circuits (PVCs) or Switched Virtual Circuits (SVCs) can be applied to ATM interfaces. The Cisco 10720 internet router does not support ATM connections.
•
VLAN—Domain, VLAN, sub-interface objects. VLAN sub-interfaces can be configured on Ethernet interfaces.

Use of Telecom Graphics Objects
Cisco EMF uses Telecom Graphics Objects (TGO) in the Map Viewer application. TGO is a TeleManagement Forum (TMF) sponsored initiative to provide standard graphical representations for network topology maps.
A TGO displays additional information icons on top of the existing object icons displayed in Map Viewer. The additional icons indicate a variety of information (for example, information on the state of the object or event status information). Figure 2-2 provides an example of a TGO.
Figure 2-2 Sample Telecom Graphical Object
An object is a representation of a network element. For example, the object could be a node or a link. Each object shown in the right window provides pictorial cues which provide information about its associated network element. The information can be structural information; for example, a network element name or state and event information such as "out of service."
Each object can display the following information about its associated network element:
•
Object name—Name that the user gives to the object
•
Object class—Class indicates a different kind of element
•
Object state—(ANSI T1-232):
–
Event unacknowledged count
–
Event unacknowledged state
–
Event outstanding state
Figure 2-3 shows an example of a Cisco 12000 chassis map displaying a few of the TGO icons that could appear.
Figure 2-3 Sample Cisco 12000 Chassis Showing Telecom Graphical Objects
Refer to the Cisco Element Management Framework User Guide Release 3.2 for further information on the type of TGO objects that can appear in the Cisco 12000/10720 Manager.

Views
C12k/10720M views can be accessed by clicking on the Viewer icon in the Cisco EMF launchpad. These views appear in the frame at the left of the window when you open the Map Viewer window (see Figure 2-4).
C12k/10720M views model hierarchical relationships between objects, both physical and logical. Objects are organized into different views and can exist in multiple views simultaneously by reference. Each object can have a number of parent and child objects. You can access C12k/10720M objects by navigating through one of the views to find the object. You can navigate through views by expanding text. Click on the + sign next to any object to expand text. A - sign next to an object indicates there is no more text to expand. Each view represents a different way of containing and grouping objects.
C12k/10720M adds specific views to the standard views supplied by Cisco EMF. The standard Cisco EMF views are the Physical and Network views (for further information on these views, refer to the Cisco Element Management Framework User Guide Release 3.2 (78-12536-01)) and the Forsetti documentation.
The number in parenthesis next to a view indicates how many top-level objects are contained within the view.
The Views section covers the following areas:
•
Component Managed View
•
Layer 3 QoS View
•
Network View
•
Physical View
•
VLAN View
Component Managed View
The Component Managed view displays all objects within the Cisco EMF system. The Component Managed view displays all the physical objects and most of the logical objects.
Figure 2-4 Hierarchy of Component Managed View
Layer 3 QoS View
The Layer 3 QoS view displays only Layer 3 QoS objects within C12k/10720M, such as the following:
•
Access Lists
•
CAR objects
•
WRED objects
You can work within this view to create and configure Access Lists or CAR or WRED objects by accessing the respective C12k/10720M menus.
Network View
This view displays all network devices within their relevant networks and subnets. The auto-discovery system of Cisco EMF uses this view to calculate which devices have already been added to the system, so that it does not try to discover the same device multiple times. For details on auto-discovery, refer to "IP Auto Discovery of the Cisco Chassis" section.
Physical View
Physical view displays all the physical objects. Objects in the Physical view are ordered according to their relative physical location.
Figure 2-5 Hierarchy of Physical View
VLAN View
The VLAN view displays the VLAN objects in C12k/10720M. The VLAN view can contain one or more domains. A domain is a user-defined grouping of the VLAN objects. This grouping may be done on a customer name basis, on logical groupings like 'Accounting Vlans' or it could be any other user maintained VLAN grouping. There can be mulitple domains in the VLAN view and each domain can contain mulitple VLAN objects. The same VLAN id can be duplicated across different domains. Each VLAN object can have multiple sub-interface objects.
Note
The sub-interface objects are shown only under the VLAN objects and in the component managed view. Only Ethernet sub-interfaces are displayed.
C12k/10720M Object States
C12k/10720M object states reflect the life cycle of an object. Whatever stage the object is in at any given time is reflected in the state type. The state of an object can change frequently, depending upon what actions are being performed on the object. All objects in C12k/10720M have a state assigned to them which appears at the bottom left corner of each FCAP window for a selected object (see Figure 2-6).
Figure 2-6 C12k/10720M Object States
The two most common object states are Normal and Decommissioned. For example, when you deploy a line card in C12k/10720M, the initial state of the line card is decommissioned. You can then commission the line card to begin active management (for details on how to commission a module, refer to the "Commissioning a Selected Module" section). When you commission the line card, it passes through two transitory states: discovery and commissioning. The commissioning process determines which state to move the object into (typically Normal). This example reflects the basic process of deploying and commissioning an object.
Certain states ripple down to any objects below. For example, if you decommission a chassis, all subchassis objects are also decommissioned. If you enable performance logging on a line card, all interfaces on the line card are also transitioned to performance logging.
By default, FCAP windows refresh at a rate dependent upon the type of window. For example, inventory windows are refreshed at a lower rate than performance windows. The average refresh rate is every 30 seconds.
The following sections describe the possible states that an object may be in and provides a description of these states.
Decommissioned State
The decommissioned state indicates that an object is not managed. When you manually deploy an object, it is normally placed into a decommissioned state.
Tip
Initially deployed objects are decommissioned to leave you with the option of managing the object or not. If you want to manage the object, you need to commission the object.
The following actions occur on a decommissioned object:
•
Active management stops
•
All sub objects are also decommissioned
Decommission buttons are located in Chassis, Module, Interface and VLAN Configuration windows. When you decommission an object, any children of that object also change their state to decommissioned. For example, if you decommission a chassis, all objects within that chassis (GRP card, line cards, interfaces, connections) are also decommissioned. If you decommission a line card, all interfaces and connections on that line card are decommissioned, and so on.
Normal State
The normal state indicates that an object is operational. When any physical object enters the normal state, C12k/10720M performs heartbeat polling on the objects. The heartbeat polling interval for chassis object is 1 minute and for all modules and interface objects, the heartbeat polling interval is 5 minutes.
Errored
When the object is in a non-operational state, it moves into the errored state. In the errored state, performance polling (if activated) is stopped; however, the heartbeat polling (which polls an object every 5 minutes to verify its existence and current state) continues, until the device responds positively to the heartbeat request. When the module is operational again, it responds positively to the heartbeat requests, and then moves into the state which it previously held.
Performance Logging On
When performance logging is started on an object in the Normal state, the object moves into the Performance Logging On state. This means that the performance data is collected on the object and is viewed in the Performance windows or the Performance Manager windows. Performance logging is enabled for GRPs, interfaces and VLAN sub-interfaces. You can enable performance logging on a global scale or on an individual object basis. Enabling global performance logging puts all subchassis objects into a performance logging on state. However, remember that only GRPs and interfaces actually collect performance data. (For more information on global performance logging, refer to the "Starting Global Performance Logging" section.
Performance logging occurs every 15 minutes. This means that when you enable performance logging or global performance logging initially on an object, it takes 15 minutes for the data to be collected and displayed in C12k/10720M performance menus.
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. C12k/10720M 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 C12k/10720M. For example, say you are expecting an ATM OC-3 line card. So you predeploy and perform offline configuration in C12k/10720M 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 C12k/10720M 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 C12k/10720M 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 C12k/10720M when an Cisco IOS Download is being performed.
•
Reset—Temporary state that is assigned to objects in C12k/10720M during Cisco IOS Download, when the device is rebooted for the new image to take effect.
•
Discovery—Temporary state that is assigned to objects in C12k/10720M 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.
