Port class guidelines and default settings 7 Port class guidelines and default settings There are different recommendations and default settings for the physical port, the E_Port, and the FOP_Port and FCU_Port. Please refer to the following sections and plan carefully before you begin configuring the port. • "Physical port setting guidelines" • "E_Port subclass setting guidelines" • "FOP_Port and FCU_Port subclass setting guidelines" NOTE E_Ports and VE_Ports are not supported in Access Gateway mode. Physical port setting guidelines For the physical port, use the default settings listed in Table 15 for all areas and alarms except for Invalid Transmission Words and Invalid CRC Count. For Invalid Transmission Words and Invalid CRC Count, the alarms should be set at two points: a low boundary and a high boundary, with the goal to alarm as the number of invalid words per minute rises above the low boundary and again as it rises above the high boundary. it is recommended that you set the high boundary at 25 and set the alarms to alert the error log any time this high boundary is exceeded. Port class default settings Table 15 provides default settings for areas in the Port class.
