Port class guidelines and default settings
7
• Area: Class 3 (C3) Discards
Unlike the other areas, take a conservative approach for the C3 Discards area. Use the default
settings and configure the alarms for Above. The goal is to locate issues with the device or its
infrastructure, so monitor the data to help isolate issues. Port fencing is one of the
recommended solutions for isolating issues.
• Area: Trunk Utilization
The Trunk Utilization area is new; therefore, recommended settings are not yet available. Use
the default settings, monitor the results, and adjust your settings accordingly.
• Areas: Primitive Sequence Protocol Error, State Changes
These areas are not used for monitoring; therefore, leave the default alarm settings at 0.
FOP_Port and FCU_Port subclass default settings
The following table provides default settings for areas in the FOP_Port and FCU_Port subclasses.
Port fencing can only be enabled or disabled for the following areas for the FOP_Port and FCU_Port
class:
• Link Failure Count
• Loss of Synchronization Count
• Primitive Sequence Protocol Error
• Invalid Transmission Word
• Invalid CRC Count
• Class 3 Discards
