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 determine the high boundary at
which the port would be fenced, so monitor the high boundary and change the settings
accordingly.
•
Area: Trunk Utilization
Set the high boundary to 75 percent and the alarms to Above and In-Between conditions.
These settings indicate if the 75 percent threshold is exceeded and for how long.
•
Areas: Primitive Sequence Protocol Error, State Changes, Utilization, Packet Loss
Use the default settings.
E_Port class default settings
Table 17 provides default settings for areas in the E_Port class.
Port fencing can be enabled or disabled for the following areas for the E_Port class:
•
Link Failure Count
•
Loss of Synchronization Count
•
Primitive Sequence Protocol Error
•
Invalid Transmission Word
•
Invalid CRC Count
