Explains what controllers are in the system and outlines their roles, key attributes, and significance within the platform.
There are three types of controllers for the line card. The controllers are the optics controller, the ethernet controller, and the coherent DSP controller. This chapter describes the procedures used to configure these controllers.
Automatic-In-Service
This section explains how automatic-in-service features enable controllers to transition to in-service state after maintenance, manage soak times, and suppress alarms.
Display AINS configuration
Use this procedure to verify the AINS soak status and timer information for various controller types.
FEC
This section explains how forward error correction methods add redundancy during data transmission, enabling receivers to detect and correct transmission errors without retransmission.
Laser squelching
This section explains how laser squelch mechanisms operate on Ethernet controllers, their benefits in fault handling, and the differences across card types.
Hold-off timer
This section describes hold-off times, their function in trunk fault scenarios, and their impact on network stability.
Idle Insertion for Ethernet controllers
This section explains how idle insertion enables pre-traffic link verification and fault isolation between high-speed Ethernet controllers.
FlexO GID and IID
This section explains how FlexO Group Identifiers (GIDs) and Instance Identifiers (IIDs) are used to enable flexible, scalable, and efficient transport of OTU signals on trunk ports.
LLDP Drop
This section explains the LLDP drop feature and its impact on supported and unsupported hardware.
Link Layer Discovery Protocol (LLDP) support on management interface
This section explains the role and attributes of Link Layer Discovery Protocols (LLDP and CDP) when used on management interfaces, including their advantages, limitations, interoperability, and configuration options.
MAC address snooping on client ports
This section explains how MAC address snooping features help identify connected neighbors on client ports and overcome networks where LLDP cannot be used.
Transmit shutdown
This section explains how transmit shutdown features control and disable optical transmit power on trunk optics controllers.
Loopback
This section explains loopback interfaces, their usage in network equipment, configuration conditions, and related alarm behaviors.
Loop-and-drop mechanism on Ethernet controller
This section explains how loop-and-drop mechanisms isolate traffic during diagnostic loopback operations on Ethernet controllers to prevent test traffic from reaching routers and causing false alarms.
Loop-and-drop mechanism on coherentDSP controller
This section explains the loop-and-drop mechanisms on coherentDSP controllers and how they replace previous loop-and-continue mechanisms to enhance network fault indications.
Restore factory settings
Use this procedure to restore the NCS 1014 to its default factory configuration, erasing all system settings, usernames, passwords, and IP addresses.
Headless mode
This section explains how headless mode enables uninterrupted traffic flow on the NCS 1014 during control plane disruptions.
Trail Trace Identifier
This section describes trail trace identifiers, their role in network signal identification, and configuration capabilities.
Configure chromatic dispersion
Use this procedure to configure chromatic dispersion on optics controllers for 1.2T, 2.4T, and 2.4TX cards.
Configure Transmit Power
Use this procedure to configure the transmit power for trunk (CIM8 and PICO) optics within a defined range to optimize optical signal performance.
Configure laser bias current high threshold
Use this procedure to configure the laser bias current high threshold on an optics controller to monitor and maintain optimal performance.
Configure differential group delay threshold
Use this procedure to configure the threshold value for the maximum acceptable differential group delay (DGD) on trunk optics controllers.
Configure optical signal to noise ratio
Use this procedure to configure the minimum acceptable optical signal to noise ratio (OSNR) on supported controller optics cards to ensure signal quality and system alarm function.
Configure receive power threshold
Use this procedure to configure the high and low optical power thresholds that determine alarm behavior for received signals on 1.2T, 2.4TX, and 2.4T optical cards.
Frequency
Use this procedure to configure the frequency on trunk ports of transponder line cards to ensure compatibility and optimal performance.
CCMD-16 controllers
This section describes the types, automatic creation, and viewing commands for CCMD-16 controllers on NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards.
Configure Controller Parameters for NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L Cards
This section lists and explains the software-supported controller parameters, operational attributes, and CLI commands for NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L line cards.
Verify Rx VOA fixed ratio to zero
Use this procedure to configure the Rx VOA attenuation to a fixed ratio of zero to disable the Rx VOA completely.
Last link flap detection
This section lists the output formats, supported controllers, and operational details for the last link flap detection parameter in Cisco NCS 1014 transponder controllers.
