C.2 Card Default Settings
Changes that are made manually to most node-level default settings override the current settings,
whether default or provisioned. If you change node-level default settings, e ither by using the Defaults
editor or by importing a new defaults file, the new defaults reprovision the node immediately for all
settings except those relating to protection (1+1 bidirectional switching, 1+1 reversion time, 1+1
revertive switching, bidirectional line switched ring [BLSR] ring reversion time, BLSR ring revertive
switching, BLSR span reversion time, and BLSR span revertive switching). Settings relating to
protection apply to subsequent provisioning.
Note Changing some node-level provisioning through NE defaults can cause CTC disconnection or a
reboot of the node in order for the provisioning to take effect. Before you change a default, check
in the Side Effects column of the Defaults editor (right-click a column header and select
Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for
that default.
C.2 Card Default Settings
The tables in this section list the default settings for each SONET card. Cisco provides several types of
user-configurable defaults for Cisco ONS 15454 optical, electrical, storage access networking, and
Ethernet (or data) cards. Types of card defaults can be broadly grouped by function, as outlined in the
following subsections. For information about individual card settings, refer to the “Change Card
Settings” chapter of the Cisco ONS 15454 Procedure Guide.
Note To view DWDM card defaults consult the Cisco ONS 15454 DWDM Reference Manual.
Note When the card level defaults are changed, the new provisioning d one after the defaults have changed is
affected. Existing provisioning remains unaffected.
The following types of defaults are defined for SONET cards.

C.2.1 Configuration Defaults

Most card-level and port-level configuration defaults correspond to settings found in the CTC card-level
Provisioning tabs.
Note The full set of Automatic Laser Shutdown (ALS) configuration d efaults can be found in the CTC
card-level Maintenance > ALS tab for supported cards. ALS defaults are supported for OC3-8,
OC-48ELR, OC-192, OC192-XFP, MRC-2.5G-4, and MRC-12 cards.
Configuration defaults that correspond to settings that are reachable from the CTC card-level
Provisioning tabs (except as noted) include the following types of options (a rranged by CTC subtab):
• Line—(DS-N, EC1-12, OC-N, MRC-12, MRC-2.5G-4, G-series, and CE-series cards) Line-level
configuration settings.
