Critical Bug Fixes in Release

The following critical issues have been resolved in Release

  • In a mixed flex and legacy setup, when a circuit is created and added/dropped on a legacy node, PMI is incorrectly raised on the legacy line Rx if LOS-P alarm is present for that specific channel.

  • The attribute name in CERENT-ENTITY-MIB (entityx.mib) is incorrect.

  • CTC launcher version is incorrect.

The following known issues are present in R10.9.0.1:

  • When NE Defaults are exported and imported without any change in R10.9.0.1, CTC throws an error message that NODE.powerMonitor.EHBATVG -57.7 is not a valid value.

  • PWR-CON-LMT alarm is raised during upgrade or revert operation from R10.8 to R10.9.0.1 and the other way round.

This section lists the software features and enhancements introduced in Release 10.9.

400G-XP-LC Enhancements

  • The cross-connect circuit bandwidth supported are ODU2, ODU2e, and ODU4.

  • The OPM_10x10G and OPM-100G slice modes are supported for OTN cross-connect circuits.

  • The new payloads supported for the OTNXC operating mode are OC192/STM64, OTU2, OTU2e, OTU4, and 100GE.

  • The new payloads supported for the MXP operating mode are OC192/STM64 and OTU2e.

  • The ODU4 internal ports on the 400G-XP-LC card support configuration of Pseudo Random Binary Sequence (PRBS) with all operating modes.

  • The 2x150G 8QAM modulation format is configurable on the 400G-XP MXP trunk ports. It can be done by selecting M_150G as the Trunk Operating mode. The M_150G mode is not available for cross-connection and regeneration configurations. The enhancement is supported with the NCS2K-S pkg.

  • The Trunk GCC0 configuration is supported on the 400G-XP-LC card. The supported GCC0 rate on the 400G-XP-LC card is 1200K. The card supports provision of one GCC0 channel for each of the trunk ports. In case of OTU4C3 (8QAM) payload, only one GCC0 channel is configurable on the second trunk port.

  • The 400G-XP-LC card provides encryption capability on the OTU4 ports. This card provides confidentiality of the data, which is sent over a fiber optic communication channel, using Next Generation Cryptography. The MXP operating mode supports the encryption feature.

For more information, see the Provisioning Transponder and Muxponder Cards chapter in the Cisco NCS 2000 Series Line Card Configuration Guide, Release 10.x.x.

Media Channel Group Restoration

In case of a fiber cut in a path, the media channels in a media channel group (MCHG) are restored using another available path. This helps reduce the network outage time. The user has an option to shrink the media channel group after restoration to the minimum size. This is required to maintain all media channels in the same group. All the media channels inside a MCHG inherit the restoration settings of the MCHG. The feature is supported with the NCS2K-S pkg.

For more information, see the Provisioning Transponder and Muxponder Cards chapter in the Cisco NCS 2000 Series Line Card Configuration Guide, Release 10.x.x.

Remote TXP Shelf Node

This feature remotize the transponder present in the different nodes of the optical network. The transponder node containing a set of transponders is physically connected to the ROADM node using the external PPC. The transponder node and the ROADM nodes must be on the same IP routing domain to have a control plane running on the entire network. The feature is supported with the NCS2K-F pkg.

For more information, see the Creating Optical Channel Circuits and Prvisionable Patchcords chapter in the Cisco NCS 2000 Series Network Configuration Guide, Release 10.x.x.

OTDR Functionality for OPT-RAMP-C and OPT-RAMP-CE Cards

For OPT-RAMP-C and OPT-RAMP-CE cards, the direction of OSC propagation is opposite to the direction of C-band signal unlike other amplifier cards. Hence, OTDR functionality is reversed when used with OPT-RAMP-C and OPT-RAMP-CE cards. For example, when OTDR scan is started for LINE-RX direction, the scan is performed in LINE-TX direction.

TLS Version Support

The supported version of Transport Layer Security (TLS) protocol is 1.2.

Known Issue

The TNC card resets when alarm suppression is enabled over USB.

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 For more information on BST, see Bug Search Help.
