Technology Description

IPoDWDM

IPoDWDM is a network architecture approach that integrates layer 1 (Optical) and layer 3 (IP) technologies by combining DWDM transponder features and functions into the router interface. Instead of being limited to a short-reach gray wavelength, the router is able to emit a tunable, ITU-grid compatible colored wavelength, with G.709 Digital Wrapper and Enhanced Forward Error Correction (EFEC) functions. This change provides multiple advantages, including savings in capital and operational expenditures due to the elimination of multiple transponder shelves, cross connect shelves, and associated short-reach interfaces. The total number of opto-electronic components is reduced by 50 percent, further lowering costs, improving availability, lowering the time needed to provision services on the network, and increasing MTBF. It also halves the number of patch cables needed at the terminating sites, reduces power consumption, and shrinks the equipment physical footprint.

Note ANA 3.6.6 provides support for IPoDWDM on CRS-1 devices running IOS-XR only.

Inventory and Information Model Objects (IMOs)

This section describes the following IMO:

•DWDM Interface

DWDM Interface

The DWDM Interface object represents a DWDM controller physical termination point. It is accessed by the Module containing it.

Table 18-1 DWDM Interface (IDWDM)

Attribute Name	Attribute Description	Scheme	Polling Interval
LaserStatus	Status of the laser (on, off)	IPCore	Configuration
TxPower	Transmit power level. Values are in units of 0.1 dBm and can range from -190 to +10. This corresponds to a range of -19 dBm to +1 dBm	IPCore	Configuration
RxPower	Receive power level. Values are in units of 0.1 dBm and can range from -200 to 0. This corresponds to a range of -20 dBm to 0 dBm	IPCore	Configuration
Loopback	Transponder loopback setting (none, internal, line)	IPCore	Configuration
ControllerStatus	Status of the controller status (up, down).	IPCore	Configuration
WavelengthBand	Indicates the wavelength band (C-band, L-band).	IPCore	Configuration
MsaItuChannel	Multi Source Agreement (MSA) ITU channel number. The ITU channel number is an integer between 1 and 83 (for the C-band) or between 106 and 185 (for the L-band).	IPCore	Configuration
Frequency	Frequency of the channel, in terahertz.	IPCore	Configuration
Wavelength	Wavelength corresponding to the channel number, in nanometers.	IPCore	Configuration
G709Status	The raw string output value of G709 status, as retrieved using the CLI.	IPCore	Configuration
DetectedAlarms	Alarms detected by the controller (None, LOS, LOF, LOM, IAE, OTU-AIS, OTU-BDI, OTU_SD_BER, ODU-AIS, ODU-BDI, etc.)	IPCore	Configuration
AssertedAlarms	Alarms indicated to be reported by the user (None, LOS, LOF, LOM, IAE, OTU-AIS, OTU-BDI, OTU_SD_BER, ODU-AIS, ODU-BDI, etc.)	IPCore	Configuration

Vendor-Specific Inventory and IMOs

There are no vendor-specific inventory or IMOs for this technology. Currently, only the Cisco CRS-1 device running IOS-XR is supported.

Network Topology

There is no network topology to be discovered specifically for IPoDWDM. SNMP is used to discover physical inventory attributes for DWDM controllers in the chassis, and models them as it does other physical ports.

Service Alarms

The following alarms are supported for this technology:

•Port Down/Port Up

•Card Out/Card In

•Card Down/Card Up

For detailed information about alarms and correlation, see the Cisco Active Network Abstraction 3.6.6 User Guide.
