Port type: E_Port
E_Port, FOP_Port, and FCU_Port guidelines represent a more aggressive approach in most areas
than physical port guidelines, because failing or failed E_Ports, FOP_Ports, and FCU_Ports in a
large fabric can cause serious fabric-wide issues if not detected early.
The following examples represent a sample configuration for an E_Port. See “E_Port subclass
setting guidelines” on page 61 for detailed setting recommendations for each area.
Configuring an E_Port with an Invalid CRC Count area
Invalid Cyclic Redundancy Check (CRC) count errors on a port can represent noise on the network
or a potential hardware problem.
1. Enter the portThConfig command using the following parameters:
portthconfig --set e-port -area crc -highth -value 20 -trigger above -action
raslog,snmp,email,portlog
• Excessive CRCs on E_Ports lead to fabric congestion and possible frame drops; therefore,
change the high threshold value from 1000 (the default) to 20 (per minute).
• Triggers specify actions for in-range port behavior. Set the trigger to above.
• Set the action to collect all notifications (raslog, snmp, email, and portlog).
2. Apply the changes.
portthconfig --apply e-port -area crc -action_level cust -thresh_level cust
Configuring an E_Port with an Invalid Transmission Words area
Invalid Transmission Words occur when a word does not transmit successfully, resulting in
encoding errors. Invalid word messages usually indicate a hardware problem.
1. Enter the portThConfig command using the following parameters:
portthconfig --set e-port -area itw -highth -value 40 -trigger above -action
raslog,snmp,email,portlog
• Excessive CRCs on E_Ports lead to fabric congestion and possible frame drops; therefore,
change the high threshold value from 1000 (the default) to 40 (per minute).
• Triggers specify actions for in-range port behavior. Set the trigger to above.
• Set the action to collect all notifications (raslog, snmp, email, and portlog).
2. Apply the changes.
portthconfig --apply e-port -area itw -action_level cust -thresh_level cust
