This section lists the software features and enhancements introduced in Release 11.1.

Submarine Line Terminal Equipment (SLTE)

In Submarine Line Terminal Equipment (SLTE) topology, the NCS2K-20-SMRFS= card of NCS 2000 node aggregates channels from transponders, say NCS 1004. If there is more than one channel SMR card, they are connected by the 1*6 AD-CFS passive module. The aggregated channels from this passive module are transmitted to the fan-out module that covers signals from other geographical locations and the SMR card. The channels are then transmitted to the SLTE SMR card that faces the submarine system.


The NCS2K-20-SMRFS= card supports SLTE. The licensed version of the card does not support SLTE.

For more information, see the Node Reference chapter in the Cisco ONS 15454 DWDM Network Configuration Guide, Release 11.x.x..

400G-XP-LC Enhancements

Interoperability with 10x10G-LC card - The OPM_PEER_ODU2 and OPM_PEER_ODU2e slice modes are available on Slice 2 when the 400G-XP-LC card is configured in the MXP mode for any trunk configuration. These slice modes support interoperability with a peer 10x10G-LC card. The peer 10x10G-LC card can only be installed in an even slot of the Cisco NCS 2006 or Cisco NCS 2015 chassis. The payloads supported on the 10x10G-LC card are OTU2, OTU2e, OC192/STM64, and 10GE.

For more information, see the Provisioning Transponder and Muxponder Cards chapter in the Cisco ONS 15454 DWDM Line Card Configuration Guide, Release 11.0.

GMPLS Enhancements

  • Restoration is supported on the Regen NCS 1004.

  • Manages greater than 50dB high span loss from validation.

  • Supports the 200G QPSK from the NCS 1004.

For more information, see the Creating Optical Channel Circuits and Provisionable Patchcords chapter in the Cisco ONS 15454 DWDM Network Configuration Guide, Release 11.x.x.

LOGO Expert Mode

When the Expert mode is configured for an optical side, spectral parameters such as Linear XT avg, Linear XT Stdev, Non-linear XT avg and Non-linear XT Stdev are used by the control plane for optical validation. These parameter values are obtained from the XML file. These spectral values must not be modified, unless instructed by the Cisco TAC representative.

For more information, see the Creating Optical Channel Circuits and Provisionable Patchcords chapter in the Cisco ONS 15454 DWDM Network Configuration Guide, Release 11.x.x.


The alarms introduced in Release 11.1 are:

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.
