Appendix C Network Element Defaults
C.2.2 Threshold Defaults
• ALS (card-level Maintenance > ALS tab)—(STM1-8, STM16, STM64, STM64-XFP, and MRC-12
cards) ALS configuration defaults.
• IOS (card-level IOS tab)—(ML-series cards) Console port and RADIUS server access settings.
• Ether Ports—(CE-series cards) Line configuration settings (including 802 class of service [IEEE
802.1p CoS] and IP type of service [ToS]).
• POS Ports—(CE-series cards) Line configuration settings.
Note Line configuration defaults for the CE-100T-8 card apply to both Ethernet port and packet-over-SONET
(POS) port settings where the same setting exists for both.
Note For further information about supported features of each individual card, refer to Chapter 3, “Electrical
Cards,” Chapter 4, “Optical Cards,” Chapter 5, “Ethernet Cards,” or Chapter 6, “Storage Access
Networking Cards.”
Note For further information about IOS configuration defaults for the ML-series cards, consult the Ethernet
Card Software Feature and Configuration Guide for the Cisco ONS 15454, Cisco ONS 15454 SDH, and
Cisco ONS 15327.
C.2.2 Threshold Defaults
Threshold default settings define the default cumulative values (thresholds) beyond which a threshold
crossing alert (TCA) will be raised, making it possible to monitor the network and detect errors early.
Card threshold default settings are provided as follows:
• PM thresholds—(E1-N-14, E1-42, E3-12, DS3i-N-12, STM-N, and MRC-12 cards) Can be
expressed in counts or seconds; includes line, electrical path, and SONET thresholds.
• Physical Layer thresholds—(STM1-8, STM64, STM64-XFP, and MRC-12 cards) Expressed in
percentages; includes optics thresholds.
Threshold defaults are defined for near end and/or far end, at 15-minute and one-day intervals.
Thresholds are further broken down by type, such as Path, Line, vc4, or pbitpath for performance
monitoring (PM) thresholds, and TCA (warning) or Alarm for physical thresholds. PM threshold types
define the layer to which the threshold applies. Physical threshold types define the level of response
expected when the threshold is crossed.
Note For full descriptions of the thresholds you can set for each card, see Chapter 15, “Performance
Monitoring.”
Note For additional information regarding PM parameter threshold defaults as defined by Telcordia
specifications, refer to Telcordia GR-820-CORE and GR-253-CORE.
