Before you begin to install the software, you must check whether your system meets the following minimum software and hardware requirements:

• Hardware—Intel Core i5, i7, or faster processor. A minimum of 4 GB RAM, 100 GB hard disk with 250 MB of available hard drive space.

• One of the following operating systems:

  • Windows 7, Windows Server 2008, or later

  • Apple Mac OS X

  • UNIX workstation with Solaris Version 9 or 10 on an UltraSPARC-III or faster processor, with a minimum of 1 GB RAM and a minimum of 250 MB of available hard drive space.

  • Ubuntu 12.10

• Java Runtime Environment—JRE 1.8 and later.

• Java version 8.0

• Browser:

  • Internet Explorer

  • Mozilla Firefox

  • Safari

  • Google Chrome

The following critical issue has been resolved in Release 10.5.2.7:

• The 200G-CK-C and 100GS-CK-C cards might show issues during boot up phase.

The following critical issues have been resolved in Release 10.5.2.6:

• If static routes are configured on a controller card, it undergoes multiple reboots after a switchover or reboot.
• Alarms and protection switching may not work for LAN to WAN mode services on the OTU2XP card.
• The WSE card reboots and traffic is affected after an upgrade from R10.522 to R10.524.
• The database of the node is lost due to an incorrect OCHTrail audit.
• CTC network view is blank with Java 1.8 build 101 or higher.
• When the 80-WXC COM output set-point is lower than -22 dBm, the channel VOA has an attenuation of 18~20 dB.
• SSH TL1 session clean-up is not proper upon session time-out due to which further TL1 login is not possible.
• The MR-MXP card reboots and traffic is affected after the node is upgraded to R10.522.
• The controller cards continuously reload due to an SSH task exception on a secure TL1-enabled node.

The reversion pulse width range on PSM cards is from 10 to 200 seconds and is calculated in the following way:

Minimum reversion pulse width=ROADM delay + 10 seconds

ROADM delay = N x 5 x 2

Where:

N—Number of filter cards in the network between the source and destination PSM nodes on the working path.

5—Maximum startup delay in seconds

2—Bidirectional communication

For example, if a network has four ROADM nodes with the end nodes having PSM cards on the working path as depicted below:

[PSM - Node 1 - FILTER 1 ] ==== [FILTER 2 - Node 2 - FILTER 3 ] ==== [FILTER 4 - Node 3 - FILTER 5 ] ==== [FILTER 6 - Node 4 - PSM]

then N=6, ROADM delay=6 x 5 x 2= 60

Minimum reversion pulse width=60 + 10= 70 seconds

The OpenSSH version that is currently supported is 3.5.9.1 and will be upgraded in a future release.

The following critical issues have been resolved in Release 10.5.2.4:

• Traffic hit occurs due to drift in internal clocking of the MR-MXP card.

• MFGMEM failures on ancillary units of Cisco NCS 2015 chassis.

• The TNC card undergoes a roll reboot when the ECU2 or ECU-S unit is installed in Cisco ONS 15454 M6 shelf.

• Unexpected packet size returned through TL1 over an SSH connection.

• APC failure in a mixed network of legacy (or UTS) and flex nodes, if a RAMAN-CTP span is present between a legacy node and a flex node.

• Unexpected reload of the TNC card during connection verification operation.

• EQPT alarm raised on the SMR20 FS card during a TNC reset.

• Traffic hit occurs when a circuit is rerouted and its wavelength is changed.

• TNCS-O and TNCE cards undergo a cold reboot during an OTDR scan if the cards are installed in the same chassis.

• OCHCC circuit creation fails when link diversity is used.

• During an upgrade from R 10.3.0.2 to R 10.5.2.4, a LOS-P alarm is raised on the 16-WXC-FS card that causes a traffic hit.

The following critical issue have been resolved in Release 10.5.2.3:

• APC fails in a mixed network of legacy or UTS nodes and flex nodes, if a RAMAN-CTP span is present between a legacy node and a flex node.

The following critical issues have been resolved in Release 10.5.2.2:

• Node restarts after a fiber restore event on the Raman span.

• Fan speed table modified for Cisco NCS 2015. Fan speed and temperature mapping was added.

• Incorrect TCA thresholds seen in 200G-CK-LC and 100GS-CK-LC cards when configured in the MXP_200G, MXP_10x10G_100G , or MXP_CK_100G mode.

• Power fluctuations seen on the EAD ports of the cascaded 80-WXC-C cards in linear systems with high number of spans.

• Traffic hits seen in WSE cards during soft resets and upgrades.

• Incorrect service state seen in amplifier card ports after a fiber cut event on a Raman amplified span with circuits in the out-of-service (OOS) state.

• Incorrect configuration sequence seen in the TNCS-O card after firmware upgrade.

• LOS-O alarm not cleared when the FAIL-HI alarm is raised on the EDRA card.

• Traffic hits seen during connection verification.

The reversion pulse width range on PSM cards is from 10 to 200 seconds and is calculated in the following way:

Minimum reversion pulse width=ROADM delay + 10 seconds

ROADM delay = N x 5 x 2

Where:

N—Number of filter cards in the network between the source and destination PSM nodes on the working path.

5—Maximum startup delay in seconds

2—Bidirectional communication

For example, if a network has four ROADM nodes with the end nodes having PSM cards on the working path as depicted below:

[PSM - Node 1 - FILTER 1 ] ==== [FILTER 2 - Node 2 - FILTER 3 ] ==== [FILTER 4 - Node 3 - FILTER 5 ] ==== [FILTER 6 - Node 4 - PSM]

then N=6, ROADM delay=6 x 5 x 2= 60

Minimum reversion pulse width=60 + 10= 70 seconds

This section highlights the new enhancements for Release 10.5.2.1. For detailed documentation about these enhancements, see the user documentation.

In Release 10.5.2.1, a traffic hit may occur on the MR-MXP card installed in the or Cisco NCS 2015 chassis in the following scenarios:

• A soft reset of the single or dual control cards.
• A hard reset of the single or dual control cards.
• A software upgrade from an earlier release to Release 10.5.2.1.

Due to memory limitations, TCC2/TCC2P cards are not supported as the node controller in multi-shelf configuration. Hence, it is recommended to use TCC3 card as the node controller in multi-shelf configuration. However, the TCC2/TCC2P cards can be used as a subtended controller and also in a stand-alone configuration.

This section highlights new features for Release 10.5.2. For detailed documentation of each of these features, see the user documentation.

Use the Bug Search Tool (BST) to view the list of outstanding and resolved bugs in a release.

BST, the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The tool allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has provision to filter bugs based on credentials to provide external and internal bug views for the search input.

To search for a specific bug, go to Bug Search Tool (BST) and search the bug ID in the Search For field. For more information on BST, see Bug Search Help.
