Table 9-10 describes the fields and controls in the Trap Control tab.
Table 9-10. Add Logical Port: Trap Control Tab
Field Description
Congestion (%) 
(10-100)
Enter a value between 0 and 100 to indicate the threshold 
percentage for generating and sending traps to the NMS for this 
logical port. A congestion trap is generated and sent to the NMS if 
the rate of congestion over a one-minute period exceeds the 
percentage value you enter.
Adjust the entered value according to how sensitive this port needs 
to be to network congestion. Options include:
• Low – Generates a trap at the first sign of congestion.
• High – Generates traps for serious network congestion. 
• Zero – (default) Disables congestion threshold. If you enter 
zero, no traps are generated for this logical port.
Frame Err/Min 
(0-13684)
Enter a value from 0 to 16384 to configure the threshold of frame 
errors on this logical port. If the number of frame errors received in 
one minute exceeds the specified number, a trap is sent to the NMS.
Adjust this value according to how sensitive this port needs to be to 
frame errors. A lower value will make the port sensitive to frame 
errors. A high value will generate traps when a significant number 
of frame errors occur within a one-minute period. 
A value of zero (default) disables this feature, which prevents traps 
from being generated for this logical port.
