Configuring Controllers

Details the configuration of optics, Ethernet, and Coherent DSP controllers on Cisco NCS 1004 line cards. It covers critical management features including AINS, FEC, laser squelching, protection switching, and diagnostic tools to ensure robust optical networking performance.

AINS overview

This section explains how Automatic-In-Service (AINS) features allow controllers to automatically transition to the in-service state after maintenance, suppressing alarms and ensuring system stability during the process.

Forward error correction

This section explains how Forward Error Correction (FEC) adds redundancy to data transmissions, enabling detection and correction of errors without retransmission in optical networks.

Laser squelching

This section explains t the laser squelch feature on Ethernet controllers in the NCS 1004 platform.

Holdoff timers

This section explains the holdoff timer feature for idle insertion on Ethernet controllers, describing its function, benefits, and use cases.

Idle insertion for Ethernet controllers

This section explains the idle insertion feature available for Ethernet controllers on the NCS 1004 platform.

Configure LLDP drop

Use this procedure to configure the LLDP drop feature for muxponder or muxponder slices on the NCS 1004 to control how LLDP frames are handled..

Daisy chain support on management ports

This section explains the daisy chain features available on management ports of the NCS 1004, including ring-like topologies that support up to five devices, main and backup paths, and specific port limitations.

DHCP client

This section explains how DHCP clients allow router interfaces to automatically acquire IP addresses and configuration information.

MAC address snooping on client ports

This section explains MAC address snooping on client ports for Cisco NCS 1004 controllers and describes feature behavior, supported controller context, and configuration considerations.

Transmit shutdown

This section explains the transmit shutdown feature on trunk optics controllers on the NCS 1004.

Loopback

This section explains the loopback features supported on Cisco NCS 1004 controllers and describes the supported cards and their capabilities.

Restore factory settings

Use this procedure to restore the NCS 1004 to its factory default settings by erasing all system configuration, including usernames, passwords, and IP addresses.

Headless mode

This section explains how headless mode enables Cisco NCS 1004 to maintain traffic forwarding during control plane disruptions.

Trail trace identifier

This section explains how Trail Trace Identifiers (TTIs) function on the NCS 1004 platform, enabling operators to trace optical signals from source to destination, ensuring signal integrity and facilitating troubleshooting.

Chromatic dispersion overview

This section explains chromatic dispersion (CD) configuration on optics controllers for the NCS 1004.

Frequency configurations

This section explains how frequency configurations enable control of optical frequencies and grid spacing for NCS 1004 line cards.

Pseudo-random binary sequence

This section explains how pseudo-random binary sequences (PRBS) enable data integrity checks on NCS 1002 and NCS 1004 trunk links without enabling client traffic.

FlexO GID and IID overview

This section explains explains how Flexible OTN (FlexO) Group Identifications (GIDs) and Instance Identifications (IIDs) enable flexible grouping and unique identification of interfaces on OTN-XP and QXP cards for the NCS 1004.

Verify FPD status of QDD ZRP pluggables

Use this procedure to verify the Field Programmable Device (FPD) status of QDD ZRP pluggables installed on the NCS 1004 using the CLI.

Automatic protection switching on OTN-XP card

This section explains how automatic protection switches (APS) operate on trunk ports of NCS1K4-OTN-XP cards in the NCS 1004 platform.
