Defining ATM UNI DCE/DTE Logical Ports
Table 4-12. Add Logical Port: Trap Control Tab Fields
Field Action/Description
Thresholds Congestion (%) (0-100)
(ATM Direct Line Trunk and ATM Network 
Interworking for FR NNI only)
Enter a value between zero (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:
Zero – (default) Disables the congestion 
threshold. If you enter zero (0), no traps are 
generated for this logical port.
Low – Generates a trap at the first sign of 
congestion.
High – Only generates traps for serious 
network congestion.
Note: Changing the value for this attribute 
does not admin down the logical port.
Frame Err/min Threshold
(ATM Direct Line Trunk and ATM Network 
Interworking for FR NNI only)
Enter a value from zero (0) to 16384 to 
configure the frame error threshold 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. 
Options include:
Zero – (default) Disables this feature, which 
prevents traps from being generated for this 
logical port.
Low – Port is sensitive to frame errors. 
High – Only generates traps when a 
significant number of frame errors occur 
within a one-minute period.
Note: Changing the value for this attribute 
does not admin down the logical port.
