3 About the Cisco ONS 15454 TL1 Reference Cartridge

This chapter describes the Cisco ONS 15454 SONET TL1 reference cartridge (Cisco 15454 TL1 reference cartridge) for Oracle Communications Network Integrity. See the following sections for more information:

This chapter also explains how to use and build the Cisco 15454 TL1 reference cartridge. See the following sections for more information:

About Actions and Processors

The Cisco 15454 TL1 reference cartridge contains the Discover Cisco 15454 TL1 action. The Discover Cisco 15454 TL1 action extends the actions from the TL1 cartridge, extending its processors to establish the TL1 connection and to set the TL1 properties. The Discover Cisco 15454 TL1 action runs the following processors in the following order:

  1. TL1 Property Initializer

  2. TL1 Property Customizer

  3. TL1 Connection Manager

  4. Cisco 15454 TL1 Device Collector

  5. Cisco 15454 TL1 Device Modeler

  6. Cisco 15454 TL1 Device Persister

The Discover Cisco 15454 TL1 action scans a device and provides a physical hierarchical model of the discovered data.

This cartridge is designed to discover Cisco ONS 15454 SONET devices only. The scan fails if you use this cartridge to discover non-Cisco or other Cisco devices.

Figure 3-1 illustrates the processor workflow of the Cisco 15454 TL1 reference cartridge.

  • RTRV-NETYPE: to get network element (NE) level details.

  • RTRV-NE-GEN: to get NE level details.

  • RTRV-INV: to get card level details.

  • RTRV-EQPT: to get card level details.

Cisco 15454 TL1 Device Modeler

This processor models the data collected by the Cisco 15454 TL1 Device Collector processor, building the hierarchical relationship for physical devices and children equipment, equipment holders, and physical ports.

Cisco 15454 TL1 Device Persister

The Cisco 15454 TL1 Device Persister persists the physical device tree to the Network Integrity database.

About Collected Data

This section discusses the data that is collected for modeling, listing, and explaining each request and response command.

Equipment Collection

This section shows the TL1 request definition and sample TL1 responses that the processors could receive from a device.

The RTRV-NETYPE request resembles the following example:

RTRV-NETYPE:[<TID>]::<CTAG>;

The RTRV-NETYPE response line is made up of a positional parameter block with the following format:

SID DATE TIME
M CTAG COMPLD
"<VENDOR>,<MODEL>,<NETYPE>,<SW_ISSUE>"
;

Example 3-1 shows an example RTRV-NETYPE response.

;

The RTRV-INV request resembles the following example:

RTRV-INV:[<TID>]:<AID>:<CTAG>[::::];

The RTRV-INV response line is made up of three parameter blocks: a positional block, followed by an empty block, followed by a named block. The response line has the following format:

SID DATE TIME
M CTAG COMPLD
"<AID>,<AIDTYPE>::[PLUGTYPE=<PLUGTYPE>],[PN=<PN>],[HWREV=<HWREV>],[FWREV=<FWREV>],[SN=<SN>],[CLEI=<CLEI>],[TWL=<TWL>],[PLUGINVENDORID=<PLUGINVENDORID>],[PLUGINPN=<PLUGINPN>],[PLUGINHWREV=<PLUGINWREV>],[PLUGINFWREV=<PLUGINFWREV>],[PLUGINSN=<PLUGINSN>],[ILOSSREF=<ILOSSREF>],[PID=<PID>],[VID=<VID>],[FPGA=<FPGA>],[MODULETYPE=<MODULETYPE>]"

;
 

The RTRV-EQPT request resembles the following example:

RTRV-EQPT:[<TID>]:<AID>:<CTAG>[::::];

The RTRV-EQPT response line is made up of four parameter blocks: two positional blocks, followed by a named block, followed by a positional block. The following format, taken from Cisco documentation, does not show the third parameter block as named, but is inferred from the example response provided. The response line has the following format:

SID DATE TIME
M CTAG COMPLD
"<AID>:<AIDTYPE>,<EQUIP>,[<ROLE>],[<STATUS>]:[<PROTID>],[<PRTYPE>],[<RVRTV>],[<RVTM>],[<CARDNAME>],[<IOSCFG>],[<CARDMODE>],[<PEERID>],[<REGENNAME>],[<PEERNAME>],[<TRANSMODE>],[<RETIME>],[<SHELFROLE>],[<FRPROLE>],[<FRPSTATE>],[<FRPHOLDOFFTIME>],[<ADMINCVLAN>],[<ADMINSVLAN>],[<CFMSTATE>],[<CCTIMER>],[<SWITCHWITHCRCALARM>],[<CRCTHR>],[<CRCPOLLINTRVL>],[<CRCSOAKCOUNT>]:<PST>,[<SST>]"

Note:

Equipment holders cannot be discovered directly, so they are automatically created and populated. Because the cartridge is for a Cisco ONS 15454 SONET, the cartridge will create the shelf with 17 slots ready to be populated with card equipment. For other models, a mapping file can be used to list how many slots each model has based on the RTRV-NETYPE: MODEL field.

Because equipment holders are not discoverable, they are created without a specification.

Model Correction

Model correction occurs when the TL1 information received through discovery does not conform to the Information Model or is incomplete and therefore cannot be saved to the Network Integrity database.

The Cisco 15454 TL1 reference cartridge applies model corrections in the following cases:

Using the Cisco 15454 TL1 Reference Cartridge

This section describes how to use the Cisco 15454 TL1 reference cartridge.

Setting Up a Scan

The Cisco 15454 TL1 reference cartridge does not introduce any new scan parameter groups. Because the Cisco 15454 TL1 reference cartridge extends the TL1 cartridge, the configurable scan parameter groups are those from the TL1 cartridge.

See "Using the TL1 Cartridge" for information about creating a scan.

TL1 Gateway Discovery

The Cisco ONS 15454 SONET device can act as a TL1 gateway, through which the Cisco 15454 TL1 reference cartridge can discover other devices connected to the gateway. When discovering a TL1 gateway, you can configure and filter the list of returned NEs in the Network Integrity UI.

To discover TL1 devices through a Cisco ONS 15454 SONET TL1 gateway, set up a scan and set the following Advanced TL1 scan parameter groups:

  • Set the Gateway Discovery list to True.

  • In the Gateway NE List Command field, enter the following TL1 request: RTRV-MAP-NETWORK:[<TID>]::<CTAG>;.

    The RTRV-MAP-NETWORK request collects the list of devices that are in the span of control of the device that is acting as a TL1 gateway.

  • In the Gateway Response ID Section field, enter 0.

  • In the Gateway Response ID field, enter 1.

The response line has the following format:

SID DATE TIME
M CTAG COMPLD
"<IPADDR>,<NODENAME>,<PRODUCT>"
;

Example 3-5 shows an example RTRV-MAP-NETWORK response.

M 001 COMPLD
"172.20.222.225,TID-000,15454"
;

Property Groups

The Cisco 15454 TL1 reference cartridge uses a property group called Cisco15454Cards as a mapping table for the modeling processor to create physical ports on the cards. You can modify, add, or remove properties in this property group using the Enterprise Manager MBean Browser.

In the MBean Browser, this property group is found at the following location:

Discover Cisco 15454 TL1:Cisco 15454 TL1 Device Modeler:Cisco15454Cards

See Network Integrity System Administrator's Guide for more information about property groups and the MBean Browser.

Table 3-6 shows the preconfigured values for the Cisco15454Cards property group.

Table 3-6 Cisco15454Cards Property Group Values

Name Example Value

OC3IR4

10GEXP

The discovered card name is taken from the AIDTYPE field in the RTRV-INV TL1 response. When adding new entries, remove spaces and dashes from the card name. For example, if the AIDTYPE is OC3-IR-4, enter the name in the property group as OC3IR4.

If the AIDTYPE of a card cannot be found in the table, no physical port is created under the card.

Discovered Results

Discovered results have a result group for each device.

Table 3-7 lists the specifications that are used to model entities discovered by the Cisco 15454 TL1 reference cartridge in the Information Model.

The tree below shows the hierarchy of the modeled devices:

PhysicalDevice (Cisco 15454 Physical Device)
    Equipment (Cisco 15454 Shelf)
        EquipmentHolder (Specificationless entity)
            Equipment (Cisco 15454 Card)
                PhysicalPort (Specificationless entity)
 

Physical device and shelf entities are modeled explicitly as Cisco model-specific specifications.

Cards are modeled using a generic Cisco 15454 card specification, instead of a card-specific specification. Depending on the inventory system used, you might want to explicitly model each card type as a specification.

Equipment holder (slot) entities are modeled without a specification because slots are not directly discoverable. Therefore, no parameters beyond the base entity attributes are populated. Because a slot is not a physical object, there is no need to explicitly define a specification for it. By creating a slot without a specification, you can extend the cartridge to assign any custom specification you require.

Ports are not directly discoverable. You can use and develop a property group to model ports on cards. See "Property Groups" for more information.
