Configuring IPoDWDM


This chapter provides information about configuring IP over dense wavelength-division multiplexing (IPoDWDM) on the Cisco 7600 Series Ethernet Services Plus (ES+) and Ethernet Services Plus T (ES+T) line cards on the Cisco 7600 series router.

IP over DWDM can be configured on the following Cisco 7600 Series ES+ Extended Transport (ES+XT) line cards:

76-ES+XT-2TG3CXL

76-ES+XT-4TG3CXL

76-ES+T-2TG

76-ES+T-4TG

76-ES+XC-20G3C

76-ES+XC-20G3CXL

76-ES+XC-40G3C

For more information about the commands in this chapter, see the Cisco IOS Release 12.2 SR Command References at http://www.cisco.com/en/US/products/ps6922/prod_command_reference_list.html.


Note Unless specified otherwise, the information provided in this chapter is applicable to ES+XT, ES+T and ES+XC line cards. IPoDWDM is supported on ES+XC line cards from SRE1 and later releases.


WAN PHY and OTN Support on ES+XC Combination Line Cards

The 10GE ports on the ES+ and ES+T line cards are hardware, which are capable of supporting the Optical Transport Network (OTN) and Wide Area Network (WAN) PHY. This feature provides the software functionality to support OTN and WAN PHY on ES+ and ES+T line cards on Cisco 7600 series router platforms. WAN PHY leverages 10 Gig SONET infrastructure and accesses WAN facilities using:

Dark Fiber

Dark Wavelengths

SONET TDM Networks

This feature provides low cost optic solutions required for short distances networks that implement store and forward network design requiring no optical amplifiers.

The OTN is based on the Optical Transport Hierarchy (OTH) developed by ITU. The OTN is based on the network architecture defined in ITU G.872 "Architecture for the Optical Transport Network (OTN)". The G.872 standard defines an architecture composed of the Optical Channel (OCh), Optical Multiplex Section (OMS), and Optical Transmission Section (OTS). The use of digitally framed signal with digital overhead for optical channel enables you to implement the management requirements of OCh. It also allows the use of Forward Error Correction (FEC) system to improve the system performance. The two new digital layer networks introduced to implement this feature are ODU and OTU.

OTN architecture (ITU-T G.872 standard) defines two interface classes:

Inter-domain interface (IrDI): The OTN IrDI interface class defines the interface (with the 3Rs [Reamplification, Reshaping and Retiming] processing) at each end of the operator interface. the operator interface can also be the interface between different vendors within the same operator

Intra-domain interface (IaDI): The IaDI interface class defines the interface within an operator or a vendor domain.

OTN has the following advantages:

Stronger forward error correction

More levels of Tandem Connection Monitoring (TCM)

Transparent transport of client signals

Switching scalability

Restrictions and Usage Guidelines

When configuring the WAN PHY / OTN support on ES+ and ES+T line cards, follow these restrictions and usage guidelines:

The distances between the two switching equipments using the WAN PHY and the DWDM facility depends on the XFP used. Refer the data sheets of relevant XFP.

The MAC address is common for WAN PHY and LAN PHY. The WAN PHY operates at a rate compatible with the payload rate of OC-192c/VC-464c.

Configuring ITU-T G.709 Transport Modes

Use the transport-mode command in interface configuration mode to configure LAN, WAN, and OTN transport modes. The transport-mode command otn option has the bit-transparent sub-option, using which bit transparent mapping into OPU1e or OPU2e can be configured.


Note The hardware combination of Cisco-INTEL OC192 + 10GBASE-L XFP is not supported because of bit rate incompatibility between INTEL XFP and OTN for the following transport mode configurations:

opu1e - 10GBASE-R over OPU1e without fixed stuffing (11.0491Gb/s)

opu2e - 10GBASE-R over OPU2e with fixed stuffing (11.0957Gb/s)

DWDM Provisioning

All DWDM provisioning configurations take place on the controller. To configure a DWDM controller, use the controller dwdm command in global configuration mode.

Prerequisites

The g709 configuration commands can be used only when the controller is in the shutdown state. Use the no shutdown command after configuring the parameters, to remove the controller from shutdown state and to enable the controller to move to up state.

Enabling OTN Mode Alarms Assertion

By default, all the OTN mode alarms are enabled. To control OTN alarms, disable all the alarms and enable the specific alarms by performing the following steps. Standard FEC is the default FEC mode. Use the show controller command to verify the alarm status and FEC mode. Perform the steps detailed in the section to enable OTN mode alarm assertion. Configure same transport mode or FEC mode on both the routers. The FEC modes, standard and disable, are compatible with each other.

Performance Monitoring on DWDM Controllers

Performance monitoring (PM) on DWDM controllers allows you to gather, store, set thresholds for, and report performance data for early detection of problems. Thresholds are used to set error levels for each performance monitoring parameter. During the accumulation cycle, if the current value of a performance monitoring parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) is generated. The TCAs provide early detection of performance degradation.

Performance monitoring statistics are accumulated on a 15-minute basis, synchronized to the start of each quarter-hour. They are also accumulated on a daily basis starting at midnight. Historical counts are maintained for thirty-three 15-minute intervals and two daily intervals.

The Cisco 7600 DWDM controller performs the following monitoring tasks:

Retrieves performance monitoring transmission degradation counts and statistics defined in Table 10-2.

Maintains performance monitoring parameter counts and checks against configured threshold values.

Generates performance monitoring related threshold crossing alerts (TCA).

Provides performance monitoring numbers to network engineering managers.

Table 10-2 lists the performance monitoring parameters.

Problem
Solution

Not able to disable the logging of ODU alarms on the console.

Use the no g709 odu report command in DWDM configuration mode to disable the logging.

Router(config-controller)# no g709 odu report 
 
      

For disabling the logging of OTU alarms, use the no g709 otu report command in DWDM configuration mode.


IPoDWDM Proactive Protection

Proactive Protection (PP) is a mechanism that uses Bit Error Rate (BER) from the optical drivers to detect the failure of signal transmission before it actually occurs. It also corrects the errors introduced during the transmission, or due to a degrading signal.

In IPoDWDM, the Forward Error Correction (FEC) circuitry resides on a router line card. Therefore, the router has the visibility into the BER statistics before the FEC mechanism corrects these errors. This allows the router to realize that the working path is degrading beyond a reasonable point (a threshold you can configure). At this point, the router starts its protection logic and establishes a protection path while the traffic continues to flow on the degrading working path. Depending on the failure mode, the router may have ten or even hundreds of milliseconds to move away from the working path before the FEC mechanism fails.

Proactive Protection is required because the prevailing video encoding is based on MPEG-2 and MPEG-4 standards, which uses differential coding of the frame with reference to a full frame that is only sent infrequently. When this frame (called the I-frame) is lost, a large number of users may experience a visible outage on their screens, lasting up to several seconds. High resolution encoding schemes, such as MPEG-4, are actually more prone to longer outages because I-frames are less common in the data stream. For this reason, it is important to minimize the packet loss even below the SONET or SDH benchmark, ideally aiming for zero packet loss.

Restrictions

Following restrictions apply for proactive protection:

Only the following line cards support this feature:

76-ES+XT-2TG3CXL

76-ES+XT-4TG3CXL

76-ES+T-2TG

76-ES+T-4TG

76-ES+XC-20G3C

76-ES+XC-20G3CXL

76-ES+XC-40G3C

76-ES+XC-40G3CXL

The polling interval of 10ms is not guaranteed in IOS. The actual polling intervals vary depending on the load on CPU.

You can expect a time lag while triggering or reverting the proactive protection.

Even though the configuration range offered for the thresholds is from 9E-3 to 1E-9, the working range is only from 9E-4 to 1E-7. Since the values below this range are negligible, it is rounded off to 0. The values above this range are too high, and can cause the interface to be unstable.

If you enable proactive protection, and shut down the primary interface, the Loss of Signal Reporting (LOS) will be sent to the other end. Because of this, the PP FSM goes to local state. But on the local end, where an OTU-BDI is declared, the FSM does not go to remote failed state. Because of this, the FSM states will not be in sync on both sides.

Configuring Proactive Protection

Proactive protection involves enabling the protection mechanism, configuring the threshold, polling of the fast re-route (FRR) pointers, and triggering the FRR.

Complete the following steps:

SUMMARY STEPS

1. configure terminal

2. controller dwdm slot port

3. proactive enable

4. proactive trig-threshold x-coeff y-power

5. proactive trig-window window

6. proactive rvrt-threshold x-coeff y-power

7. proactive rvrt-window window

8. end

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

configure terminal

Example:

Router# config terminal

Enters global configuration mode.

Step 2 

controller dwdm slot port

Example:

Router(config)# controller dwdm 0/1

Specifies the DWDM controller and enters DWDM controller mode.

Step 3 

proactive enable

Example:

Router(config-controller)# proactive enable

Enables automatic triggering of FEC-FRR.

Step 4 

proactive trig-threshold x-coeff y-power

Example:

Step 6 

proactive rvrt-threshold x-coeff y-power

Example:
Router(config-controller)# proactive 
rvrt-threshold 1 6

Configures the revert threshold (in the form of xE-y) to trigger reverting from the FEC-FRR route back to the original route.

Step 7 

proactive rvrt-window window

Example:

Router(config-controller)# proactive rvrt-window 20345

Configures the revert window in which reverting from the FEC-FRR route back to the original route is triggered.

Step 8 

end

Example:

Router(config-controller)# end

Saves configuration changes.

Configuration Examples

This example shows how to configure automatic triggering of FEC-FRR:

Router# configure terminal
Router(config)# controller dwdm 0/1 
Router(config-controller)# proactive enable
Router(config-controller)# proactive trig-threshold 1 5
Router(config-controller)# proactive trig-window 2045 
Router(config-controller)# proactive rvrt-threshold 1 6
Router(config-controller)# proactive rvrt-window 20345 
Router(config-controller)# end

Verification

Verify the configuration by using the show controllers dwdm proactive status command.

router#show controllers dwdm 3/1 proactive status 
Proactive Protection Status: ON
 
 
Transport admin-state: IS
Trigger threshold: 6E-4
Revert threshold: 5E-6
Trigger integration window: 2000
Revert integration window: 3000
 
 
Received APS: 0x0F
Transmitted APS: 0x0F

Troubleshooting Tips

Table 10-4 Troubleshooting Solutions for the Proactive Protection Feature

Problem
Solution

How do I verify whether or not the proactive protection is triggered?

Use the show controller dwdm 3/1 proactive status command. In the command output, check if the APS bytes on the local side is 0xAF (sent), and the remote end APS received is 0xAF. Also, use the show proactive infrastructure fsm command to check whether or not the FSM state is in local or remote failed state.

For further debugging, run the debug proactive infrastructure fsm command. You should run the debug command from the line card. In the debug output, the Tx APS bytes show the various state of FSM:

0x0F --> FSM is in Normal state.

0xAF --> FRR is triggered by PP. FSM is in Local Failed state.

0xEF --> FSM is in Local Maintenance state.

How do I verify whether or not the FRR is triggered correctly?

Check the output of the show mpls traffic-eng fast-reroute database command. This example displays the output:

router#show mpls traffic-eng fast-reroute database 
 
      
P2P Headend FRR information:
Protected tunnel               In-label Out

* Sub-LSP identifier format: 
<TunSrc>_<LSP_ID>[SubgroupID]-><TunDst>_<Tun_ID>
  Note: Sub-LSP identifier may be truncated.
  Use 'detail' display for the complete key.
 
      

Please check the state of the backup tunnel. The backup tunnel in READY state indicates that the FE FRR is not triggered. The backup tunnel in ACTIVE state indicates that the FE TRR is triggered.
