Cisco Cisco ONS 15454 M6 Multiservice Transport Platform (MSTP)
New Software Features and Functionality
The following new software features have been introduced in Release 9.6.0.3:
GMPLS Restoration and UNI
The Generalized Multiprotocol Label Switching (GMPLS) control plane supports optical restoration and User-Network Interface
(UNI) features. The GMPLS control plane is available with the Cisco ONS 15454 DWDM WSON package and is supported on the
Cisco ONS 15454, Cisco ONS 15454 M6, and Cisco ONS 15454 M2 platforms.

Cisco ONS 15454, Cisco ONS 15454 M6, and Cisco ONS 15454 M2 platforms.
The GMPLS optical restoration feature helps to restore optical circuits from a failed path to a new path using the GMPLS control
plane. The optical failure is indicated through any signal alarm such as Loss of Signal (LOS), Loss Of Signal due to absence of
payload (LOS-P), and signal failure (SF). The GMPLS control plane initiates restoration after a failure is detected on the circuit. The
restoration is supported for OCHNC and OCH trail circuits. The OCHCC restoration is provided by the underlying OCH trail circuits.

If the original path fails and restoration is enabled, the GMPLS control plane establishes an alternate restored path and traffic flows
on the restored path. The following types of restoration are supported:
on the restored path. The following types of restoration are supported:
• 1+R Restoration—The restoration is enabled for an unprotected optical circuit.
• 1+1+R Restoration—The restoration is enabled for a protected optical circuit. 1+1+R supports Protection Switching Module
(PSM), Y-Cable, and splitter protection schemes.
The GMPLS UNI is a signaling interface that is set up between the client router and the DWDM network. The GMPLS UNI allows
the router to request bandwidth from the DWDM network.

100G-LC-C, 10x10G-LC, and CFP-LC Cards
The software enhancements for 100G-LC-C, 10x10G-LC, and CFP-LC cards include the following:
• Support for low latency loopback mode on the 10x10G-LC card configured with 10GE and 10GFC payloads.
• Support for GFP mapping mode on the 10x10G-LC card configured with 10GE payloads.
• Support for OTU4 payload on the CXP port of the 100G-LC-C card.
• Support for Y-cable protection on:
◦10x10G-LC card configured in the TXP-10G or MXP-10G card mode for 10GE and 8GFC payloads.
◦10x10G-LC card configured in the MXP-10G card mode for the OC192 (STM-64) payload.
◦CFP-LC card configured with 100GE or 40GE payloads.
• Support for CXP fanout configuration on the 10x10G-LC card configured with 10GE payloads on the CXP client port.
• Support for proactive protection on the 100G-LC-C card when:
◦The 100G-LC-C card is configured in the TXP-100G mode and is connected to the Cisco ASR 9000 series router that
supports 100GE payloads on its CFP pluggable.
◦The 100G-LC-C card is configured in the RGN-100G mode and is connected to the Cisco CRS-3 router using the 100G
DWDM PLIM that supports OTU4 interfaces.
• Support for GCC on the 10x10G-LC and 100G-LC-C cards.
