New Hardware Features in Release 2.0.0

The following new hardware features were implemented in Cisco 15800/15801 Release 2.0.0:

Multi-Bay Management

Previous releases had a limitation on the number of network element (NE) bays that could be addressed. ONS 15800/15801 Release 2.0.0 implements a new architecture on a master/slave structure that allows supervision of a site as a single NE.

Optical Channels Protection

ONS 15800/15801 Release 2.0.0 introduces the optical switching unit (OSU-W) module which is capable of performing 1+1 optical channel protection. The OSU-W module protects the client signal from failures within the optical transport domain (including the WCM transponder modules). The OSU-W module is managed within the optical domain and all the information for the module is available and manageable by the element management system (EMS) for general supervision activity and by the local craft interface (LCI) in terms of maintenance activity.

New CMP Module

A new control and monitoring processor (CMP-W-2E) module is introduced in the ONS 15800/15801 Release 2.0.0. The CMP-W-2E module provides two Ethernet ports that support multi-bay management, and has an expanded RAM capacity of 128 MB.

Amplifier Power Provisioning

In order to achieve a seamless channel upgrade, the ONS 15800/15801 Release 2.0.0 enables adjustment of the amplifier power level when the channel count is modified. The goal of the amplifier power provisioning (APP) process is controlling the power per channel, while considering the following constraints:

• The power per channel in the line fiber must be maintained in a fixed range.
• The power per channel in the fiber depends on the amplifier output power and on the tolerance of any insertion loss between the amplifier output and the fiber.
• The optical amplifier modules are able to maintain a constant power level per channel working on the total output power level.

Compliance Issues for ONS 15801 Systems

ONS 15801 Release 2.0.0 guarantees the compliance with the IEC60950 standard for electrical safety aspects. The only exceptions to the IEC60950 compliance within the ONS 15801 system are the RACK-TOP-UNIT and the EOI-W module that are CE mark compliant.

New Software Features in Release 2.0.3

No new software features have been implemented in Cisco ONS 15800/15801 Release 2.0.1.

New Software Features in Release 2.0.2

The following new software features were implemented in Cisco ONS 15800/15801 Release 2.0.2.

Compatibility Checking

ONS 15800/15801 Release 2.0.2 provides a consistent compatibility checking feature that makes network troubleshooting and upgrading activities easier.

This section describes the software caveats known to exist at the time of product release.

CSCuk44021 Temporary Alarms are Generated When Restoring the Optical Signal

Temporary alarms such as loss of output modulation (LOM), laser 1 power low, and output power 1 fail may be generated by the TXP-10G-FEC modules.

Conditions

The optical traffic running through an RXT-10G-FEC module is interrupted, similar to a fiber cut, and is then restored. These temporary alarms may occur all together or individually, but usually only last a few seconds.

Workaround

None.

CSCuk42466 TL1 Agent Could Not Report QoS Alarms After an Agent Reset

The TL1 agent could not report B1 15-minute QoS alarms referring to the quarter during which it was restarted.

Conditions

This situation occurs after a reset of a network element in a terminal site where the performance monitoring is enabled.

Workaround

None.

CSCuk42396 Inserted Modules Shown as Extracted After a CMP-S Reset

Simultaneously extract CMP-S modules that control fully equipped bays. After restarting, some of the modules in the controlled bays are shown as extracted in the TL1 interface but are correctly visible in Cisco Photonics Local Terminal. Consequently, Cisco Transport Manager cannot retrieve the correct configuration.

Conditions

Each CMP-S module has control of a fully equipped bay. Extract more than one CMP-S simultaneously or reset the bays controlled by the CMP-S modules.

Workaround

After the system restart, force a TL1 MIB alignment using the following command:

INIT-SYS:: <cmp master address>:AA::1;

CSCuk41079 Agent Accepts Adding a TL1 User Name With a Hyphen

The TL1 agent does no allow cancelling addition of a new TL1 user. The returned error code is IIAC.

Conditions

When the new user name includes a hyphen, this error will occur.

Workaround

Remove the file named PASSW1.DAT from the active directory of the agent and reset the CMP module using Cisco Photonics Local Terminal, Cisco Photonics Tool Kit, or Cisco Transport Manager.

Note: By removing the PASSW1.DAT file, all of the default user accounts will be restored.

CSCuk40471 TL1 Send Time-Out While Putting a Module In Service

TL1 commands are refused with a time out error.

Conditions

This condition occurs when several modules are restored or inserted simultaneously.

Workaround

Wait for the system to complete discovery and then resend the commands. When the system is discovering many new modules, any incoming commands are queued and processed at the end of the discovery process. Commands cannot be pending for more than ten seconds, after which the command is aborted with a time-out error.

CSCuk39066 TL1 Agent Download Stops During Heavy Alarms burst or PM Retrieval

A TL1 agent download fails using Cisco Photonics Local Terminal and Cisco Transport Manager.

Conditions

One of the following conditions will cause this situation:

• The NE is receiving extended alarm bursts.
• Software download is started during a 15-minute PM retrieval.

Workaround

For condition a, perform one of the following:

• Using Cisco Photonics Local Terminal, remove the module that is generating the alarm bursts from the NE inventory. This is the recommended solution.
• Using the Cisco Photonics Local Terminal FTP protocol to perform the TL1 agent download.

For condition b, wait for a couple of minutes and start the software download again.

CSCuk38801 TL1 Log Activation Malfunction

The TL1 agent log activation does not work.

Conditions

When running TL1 commands managing log files, such as RTRV-ATTR-LOG, SET-ATTR-LOG.

Workaround

Perform the following steps:

1. Telnet on the CMP module.
2. Perform the command cd active/log to locate the directory where the TL1 log files are stored.
3. Remove both the MGMT and SYS log files.

Normal TL1 behavior is restored.

CSCuk38410 A Module is Shown as Not Present in the Cisco Photonics Tool Kit Firmware Download Window

The Cisco Photonics Tool Kit firmware download window shows a module as not present.

Conditions

Reseat the module while a firmware download on the module is in progress.

Workaround

Close and reopen the firmware download window. The module will then be shown as present and a new firmware download can be started. This situation only happens in the firmware download window.

CSCuk38332 TL1 RST Command Does Not Work

The TL1 reset command to restore a module to in-service state does not work.

Conditions

From the TL1 interface, the following TL1 command must be executed:

RST:<AID>:<CTAG>;

Workaround

None.

CSCuk38221 Cisco Photonics Local Terminal Does Not Recognize a CMP Reset After a Software Download is completed

Occasionally, Cisco Photonics Local Terminal stops responding after a TL1 agent download completes.

Conditions

After a TL1 agent software download has completed.

Workaround

Once the Cisco Photonics Local Terminal stops responding to user input requests, you can terminate the application using the operating system task manager and restart the application without impact to the recently downloaded TL1 agent. TL1 agent download can still be done using the Cisco Photonics Tool Kit embedded download feature.

CSCuk38128 CMP Locks in State 2 after Agent Restart

TL1 agent does not complete the module discovery phase and the CMP is stuck in state 2.

Conditions

This situation happens during an NE restart.

Workaround

Reset the CMP module. Since the CMP is in state 2, it cannot be connected through Cisco Photonics Local Terminal or Cisco Photonics tool Kit software. To reset the CMP module, implement the following steps:

1. Telnet the CMP module using ROOT privileges.
2. At the system prompt, type the command reset.

CSCuk37855 SCC Master Firmware Version on the CMP Master Sometimes is Missing

The SCC firmware version of the CMP master module is not reported in Cisco Photonics Local Terminal or the TL1 agent.

Conditions

The problem is not a system problem, and may only appear after resetting the NE TL1 agent.

Workaround

Since the problem is related to a timing issue, it can be solved by resetting the NE master CMP module one or more times.

CSCuk37580 Bay LED Does Not Change at Alarm Severity Change

A severity change of an active alarm on a module through the Cisco Photonics Local Terminal application is not represented on the bay LEDs.

Conditions

The NE has more than one bay. The operator wants to change the severity of an active alarm on a module in a bay with ID greater than one. The operator selects the alarm IOGen of the module through the Cisco Photonics Local Terminal application and changes the alarm severity described in the reporting attributes window.

Workaround

The problem has been fixed in TL1 agent release 2.1.0. Migration to this release of the TL1 agent is recommended.

CSCuk37072 SCF Module Mismatch on Shelf Alarms Summarizer LEDs

The SCF module reports an alarm scenario on the shelf summarization LEDs that does not match with the real shelf alarm condition. This problem is not systematic.

Conditions

The NE T11 agent is running in status 6.

Workaround

The problem can be recovered by resetting the NE master CMP module.

CSCuk36883 Unequipped Slots May Cause Loss of Equipment Monitoring

Equipped slots or shelves are shown as empty slots in Cisco Photonics Local Terminal or Cisco Transport Manager software.

Conditions

This situation may happen when the NE has unequipped slots configured.

Workaround

Remove the unequipped slots from the current NE inventory.

CSCuk36833 Column One Field in the Board Firmware Download Window Resizes Incorrectly

The board firmware download window does not allow automatic sizing of the first column when double-clicking the border.

Conditions

Double-clicking the Cisco Photonics Tool Kit board firmware download window border with the left mouse button.

Workaround

Resize the column by dragging the column border.

CSCuk36271 Wrong Configuration in a Local Host Condition

A CMP-W module is able to discover only the first bay in the NE where more than one bay is configured.

Conditions

CMP-W equipped with TL1 agent 2.0.x. The problem arises after the addition of a second bay to the NE configuration.

Workaround

This problem has been fixed in TL1 agent 2.1.0.

Perform the following steps:

1. FTP the CMP-W and log in with ROOT privileges.
2. Move to the directory \ACTIVE
3. Upload the text file CMPFILE.CFG
4. Using any text editor, change the IP address reported in the file with 192.168.67.1.
5. Save the file and download it back into the \ACTIVE directory.
6. Reset the CMP-W module.

CSCuk36029 Wrong Reset Alarm Notification is Sent to the Client

In normal operation, a TL1 TCA clear operation will send a TCA clear notification to all connected clients. In a problem operation, a TL1 TCA clear operation will also send notification of no more active alarms to all connected clients.

Conditions

The ONS 15800/15801 NE includes at least one unit with active alarms and TCAS.

Workaround

None.

CSCuk36017 Agent Does Not Show IP Address if Parameter File is Missing Last Lines

The NE is unreachable using the assigned IP address.

Conditions

A CMP network configuration file is corrupted (on the CMP flash drive) and the NE has been re-initialized.

Workaround

Use the default IP address (10.51.100.254) to connect to the NE.

Change the NE IP address to the correct one using the procedures in the technical manuals.

CSCuk36010 TL1 Does Not Manage the Persistence of Environmental Alarms Description

Environmental alarms custom descriptions for ONS 15800/15801 IOC modules are lost.

Conditions

The problem arises only on IOC modules when extracted and later inserted, or a module reset due to a firmware upgrade.

Workaround

If the problem occurs, either a MIB alignment operation (TL! command INIT-SYS with parameter value set to 1) or a CMP reset will reload the correct descriptions.

Environmental alarms can have a custom description set using the SET-ATTR-ENV command. If an IOC module with customized alarm descriptions is restarted because of removal and insertion or because of a firmware upgrade, the customized descriptions are lost. The problem does not occur with an NE restart or alignment.

CSCuk36009 Bad Format Numeric Parameters Cause a System Reload

Bad numeric parameter formats cause the system to reload.

Conditions

More than 15 digits using engineering format (such as 2.3E+23) are inserted for floating point parameter values when using a TL1 command request.

Workaround

Do not insert more than 15 digits in a TL1 command when using the engineering format notation for floating point parameter values. This impacts all TL1 commands that expect floating point parameters.

CSCuk36008 File Removal May Result in File System Inconsistency

Error code SFTF reported during Software upgrade operation using TL1 commands OPR-SWDNL, OPR-SWSTDBY, OPR-SWCMT.

Conditions

This problem may arise if the software upgrade operation is forced to abort.

Workaround

None.

CSCuk36007 TL1 Agent Does Not Handle Module Serial Number Longer than Ten Characters

The TL1 agent returns a wrong module serial number, or a serial number containing non-printable characters.

Conditions

The ONS 15800/15801 NE is equipped with a TL1 agent version 2.0(0) and includes at least one module having an 11 digit serial number.

Workaround

None.

CSCuk35931 Due to a Complete Board Alarms Clear, the NE is Declared Not Alarmed

The TL1 agent shows the NE in Normal Status - NR, even though the NE still has active alarms.

Conditions

Whenever one of the control units clears all its active alarms, but other alarms are still present on the NE.

Workaround

Either restart the CMP module using Cisco Photonics Local Terminal or Cisco Photonics tool Kit, or force a TL1 agent MIB alignment by issuing the following Tl1 command.

INIT-SYS:<AID>:<CTAG>::1;

CSCuk33706 TL1 Does Not Handle Persistence on IOGen with HEX Alpha Char Instances

Some module input/output measurement point values (IOGen) are not saved.

Conditions

This problem arises when setting IOGen values using TL1 commands for modules that have more than ten IOGen. Up to ten IOGen are correctly saved while the remaining ones are not.

Workaround

Use Cisco Photonics Local Terminal to set IOGen values for modules with more than ten measurement points. This problem applies to all of the ONS 15800/15801 modules with more than ten measurement points.

CSCuk31132 SCC Master Cannot be Downloaded with Any Other Firmware

Cisco Photonics tool Kit reports a download unsuccessfully completed message.

Conditions

Whenever firmware is simultaneously downloaded on an SCC master and any other module, the SCC master firmware is downloaded correctly while the other module firmware download fails.

Workaround

Do not download any other firmware at the same time you download the master SCC firmware. If the problem occurs, the firmware can be reloaded after the master SCC download is completed.

CSCdy18931 TXT 2.5 B1 Monitoring Boards are Shown as Empty Slots

At NE start-up, the CMP module does not reach the normal operating state.

Conditions

There are one or more 2.5 B1 monitoring transponders in the NE.

Workaround

Reset the CMP module. This operation does not affect traffic.

CSCdt35132 Changing the OADM LasTemp2 Value Does Not Change the Working Point

The LasTemp2 PM point present on the OADM circuit pack cannot be controlled by setting its working set point like the LasTemp1 PM point.

Conditions

When trying to set the OADM LasTemp2 working point.

Workaround

The working set point for the LasTemp2 cannot be changed because it is only present for backward compatibility. The OADM circuit pack only has a single grating controlled laser temperature. The firmware for the OADM circuit pack shows the presence of a virtual second PM point for backward compatibility.

CSCuk31930 Demux Modules Connected to the Control Bus Do Not Respond to the CMP Module Polling Queries

Demux modules connected to the control bus do not answer the polling queries performed by the CMP module. The Cisco Photonics Local Terminal reports an empty slot.

Conditions

Commands and environment that can cause the problem are related to high traffic conditions on the control bus.

Workaround

Caution: This workaround is traffic affecting. Obtain proper clearance before removing the demux module.

Removing and replacing the demux module resolves the problem.

This firmware release works on hardware version 73-5995-0x applied to the following modules:

• 24WD-R (800-09756-05)
• 8WD-B (800-09758-04)
• 24WD-LLR (800-10393-03)

CSCdu85293 Removed Modules Remain Visible After MIB Alignment

The modules or configured slots are still visible in TL1 after their removal from the list of configured slots.

Conditions

After removing a module from the NE list of configured slots, it is possible to retrieve the slot and inserted modules if a MIB alignment is performed from the TL1 agent interface.

Workaround

Removing one or more slots from the list of managed slots would require the NE to be reset at the end of the slot removal procedure in order for the changes to be applied. The list of configured slots is defined only during the NE configuration and installation phase.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.
• Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.
• Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
• Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://tools.cisco.com/RPF/register/register.do

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
