Changes in Release 11.1.2.3
Cisco is continuously enhancing the product with every release and this section covers a brief description of changes in this release.
TACACS Idle Timeout Considerations:
-
From release 11.1.2.3, the TACACS server sends the idle timeout value in the minutes. Previously the unit for idle timeout value was seconds. After you upgrade to release 11.1.2.3, the idle timeout value unit gets adjusted to minutes from seconds.
Example: On the TACACS server, the idle timeout value of 900 seconds gets changed to 900 minutes after you upgrade to release 11.1.2.3.
-
The default idle timeout value on the TACACS server is 60 minutes. If you set an idle timeout value on the ISE/ACS TACACS server, the TACACS authenticated sessions expire when the idle timeout value is reached. However, if the CTC client is active after the idle timeout has expired, the CTC session remains open.

What's New in Release 11.12
Cisco is continuously enhancing the product with every release and this section covers a brief description of key features and enhancements. It also includes links to detailed documentation, where available.
| Feature | Description |
|---|---|
|
Control Card and Node Configuration |
|
|
This feature allows you to upgrade the Boot ROM version, OS Kernel, and Uboot version of the fiber shuffle through CTC. |
|
|
Line Card Configuration |
|
|
This feature allows you to dynamically allocate power based on the line card operating mode. This maximises the usage of the NCS 2015 chassis slots in a 2+2 PSU configuration.This feature is supported on the 200G-CK-LC and 400G-XP-LC cards. |
|
|
Secure Unique Device Identification (SUDI) SUDI 2099 Certificates for WSE, MR-MXP, and 400G XP Cards |
This enhancement allows you to extend the usage of WSE, MR-MXP and 400G-XP-LC cards with encryption functionality beyond year 2029. This extended validity helps to avoid encryption and card upgrade failures. The existing SUDI 2029 certificate allows the user to have encryption functionality only for ten years from the card installation or until 2029 whichever is earlier. This enhancement to include SUDI certificate 2099 on the software allows the user to extend the usage of encryption functionality up to year 2099. Both the near-end and far-end nodes must use the same SUDI certificate. |
|
Network Configuration |
|
|
Custom Alien Wavelength and MEDIA CHANNEL OCH NC circuit management through CTC |
The feature allows you to create an MCH custom alien wavelength and the associated MEDIA CHANNEL OCH NC circuit specifying the following parameters through CTC:
This functionality enables you to create a medial channel of any spectrum size, for example, signal width of 34.20 GHz, modulation GB of 1.71 GHz, and filtering GB of 4.92 GHz. |
|
ZR+ configuration support on NCS 2000 with 6AD passive add or drop in colorless configuration. |
The following two alien wavelengths are supported in R11.12:
|
|
Installing the GBIC, SFP, SFP+, QSFP, XFP, CXP, CFP and CPAK Optical Modules in Cisco NCS Platforms |
|
|
|
TLS Version Support
The supported version of Transport Layer Security (TLS) protocol is 1.2.
