Before you begin to install the software, you must check whether your system meets the following minimum software and hardware requirements:
Critical Bug Fixes in Release 10.5.2.6
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.
Calculation of Reversion Pulse Width on PSM Cards
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
OpenSSH Version
The OpenSSH version that is currently supported is 3.5.9.1 and will be upgraded in a future release.
Critical Bug Fixes in Release 10.5.2.4
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.
Critical Bug Fixes in Release 10.5.2.2
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.
New Enhancements for Release 10.5.2.1
This section highlights the new enhancements for Release 10.5.2.1. For detailed documentation about these enhancements, see the user documentation.
Software Enhancement in Release 10.5.2.1
SSH file transfer protocol is supported for software download, database backup, and database restore using TL1 commands.
For detailed information on TL1, see the Cisco NCS TL1 Command Guide.
Transaction Language 1 (TL1)
This section contains a list of new TL1 commands, command syntax changes, and command response changes that have been introduced in Release 10.5.2.1. For detailed information on TL1, see the Cisco NCS TL1 Command Guide.
Scenarios that Affect Traffic on MR-MXP Card
In Release 10.5.2.1, a traffic hit may occur on the MR-MXP card installed in the Cisco NCS 2006 or Cisco NCS 2015 chassis in the following scenarios:
TCC2/TCC2P Card Support
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.
New Features for Release 10.5.2
This section highlights new features for Release 10.5.2. For detailed documentation of each of these features, see the user documentation.
Hardware
The hardware units introduced in Release 10.5.2 are:
Cisco NCS 2015 AC Shelf Assembly
The Cisco NCS 2015 AC shelf assembly has 18 vertical slots, numbered 1 to 18. The slot 2 to slot 16 are for line cards that provide 10 to 100 Gbps interconnections, slot 1 and slot 17 are for TNCS or TNCS-O cards (timing and control cards). Slot 18 is for the external connection unit (ECU). The NCS 2015 AC shelf is powered by AC power modules with 1+0, 1+1, 2+0, and 2+2 redundancy. The NCS 2015 AC shelf contains backup flash memory that supports the database (DB) and image backup in the single mode operation. The LCD unit is integrated with the fan tray assembly. The fiber or cable guide used in the NCS 2015 AC shelf provides improved fiber management. The air in the NCS 2015 AC shelf is drawn in through a two-inch air inlet at the bottom of the shelf, and expelled at the top-rear. A single NCS 2015 AC shelf supports both ANSI and ETSI standards.
For more information about the NCS 2015 shelf assembly, see the Cisco NCS 2000 Series Hardware Installation Guide.
NCS 2006 ECU-S
The NCS 2006 ECU-S is a new type of ECU for the NCS 2006. It has two USB 3.0 connections and eight USB 2.0 connections. The NCS2K-MF-6RU unit, or the NCS2K-MF10-6RU unit can be connected to the NCS 2006 ECU-S using the USB 3.0 port.
For more information, see the Cisco NCS 2000 Series Hardware Installation Guide.
Cards, Add/Drop and Passive Units Supported in Cisco NCS 2015 Chassis
The line cards released before Release 10.5.2 need a new bootcode to be installed in Cisco NCS 2015 chassis. These cards upgrade to a new bootcode automatically when they are inserted in any of the slots between slots 2 to 7 in the chassis.
For more information about the bootcode upgrade, see the Cisco NCS 2000 Series Network Configuration Guide, Release 10.x.x.
Software Features for Release 10.5.2
The software enhancements introduced in Release 10.5.2 are:

OC192/STM64, 10GE, and OTU2 payloads are supported when the 10x10G-LC card is connected with the 200G-CK-LC card.
The user can filter and view internal patchcords that are directly connected to TXP cards. To enable this feature, check the TXP Only check box, available in the Provisioning > WDM-ANS > Internal Patchcords tab in CTC. By default, this feature is disabled.
A node alias (up to 128 characters) can be configured for a node.
The power redundancy mode of an NCS 2015 chassis can be configured using CTC or TL1 commands. The user can also unselect the power modules that are not used and avoid alarms for those power modules.
The MR-MXP card supports the following operating modes:
The MR-MXP card supports feature-based licensing to support high speed and low speed encryption.
The MR-MXP card provides encryption capability at the optical layer.
The following Amplifier (AMP) gain enhancements are introduced in the Release 10.5.2:

Cisco Bug Search Tool
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.
The BST is available at Bug Search. To search for a specific bug, go to https://tools.cisco.com/bugsearch/bug/bugid. For more information on BST, see Bug Search Help.
