Network Element Defaults Guide for Cisco NCS 2000 and ONS 15454

Quick Guide to Network Element Defaults

This document serves as a reference for factory-configured (default) network element (NE) settings for Cisco ONS 15454 and Cisco NCS 2000 series platforms. These settings are managed via the Cisco Transport Controller (CTC). Users can import, export, or edit these settings using the Defaults editor in the node view.

Important: Always check the Side Effects column in the Defaults editor before modifying any default value. Changing certain node-level defaults can cause CTC disconnection or a node reboot.

Understanding Default Settings

The system utilizes three main types of defaults:

• Card-level defaults: Specific to DWDM, Transponder (TXP), Muxponder (MXP), and Ethernet cards.
• CTC defaults: Settings related to the Cisco Transport Controller interface, such as automatic routing.
• Node-level defaults: General management settings for the entire node, including security, timing, and protection.

Manual provisioning performed via the Line Card Configuration guide will override these default settings. Changes to defaults only affect cards installed or preprovisioned after the defaults have been changed.

Card-Level Defaults

Card defaults are categorized into Configuration and Threshold settings. These are accessible via the CTC card-level Provisioning tabs.

Configuration Defaults

These include settings for Line, OTN, and Card-specific parameters. For example, Automatic Laser Shutdown (ALS) configuration is available for supported cards like OSCM, OSC-CSM, OPT-BST, and others. Specific tabs (e.g., Client, Distance Extension) may only appear after a Pluggable Port Module (PPM) is provisioned.

Threshold Defaults

Thresholds define the cumulative values that trigger a Threshold Crossing Alert (TCA). These include:

• PM Thresholds: Performance monitoring (counts or seconds).
• Optical Thresholds: Client and trunk optical levels (percentages or dBm).
• OTN FEC Thresholds: Forward Error Correction counts.
• OTN G.709 Thresholds: ITU-T G.709 PM and SM thresholds.

Node-Level Defaults

Node-level settings cover a wide range of operational parameters, including:

• Circuit Settings: Administrative state and protection defaults.
• General Settings: NTP/SNTP server, time zone, and TL1 reporting.
• Security: Access control, RADIUS server settings, password policies, and grant permissions.
• Timing: BITS timing and general node timing modes (External, Line, or Mixed).
• Protection: Settings for 1+1, BLSR, Y-cable, and Splitter protection.

CTC Configuration

CTC-level defaults control the behavior of the management interface. Key settings include:

• Automatic Routing: Determines if the 'Route Automatically' check box is selected by default during circuit creation.
• Network Circuit Automatic Routing Overridable: Controls whether users can override the automatic routing setting.
• Network Map: Sets the default country map displayed in the CTC network view.

Time Zone Reference

The system supports various time zones relative to Greenwich Mean Time (GMT). When configuring node time zone defaults, ensure the value matches the required format for valid input, ranging from GMT-11:00 to GMT+14:00.
