fddi port lerAlarm Sets the link error rate (LER) value at which a link connection generates an
alarm.
Valid Minimum Abbreviation
fd po lerA
Important Considerations
■
The lerAlarm value is expressed as the absolute value of the exponent
(such as 1 x 10
-10 ). A healthy network has an LER exponent between
1 x 10 -10 and 1 x 10 -15 .
■
If the LER value is greater than the alarm setting, then SMT sends a
Status Report Frame (SRF) to the network manager software
indicating a problem with a port.
■
Set the lerAlarm value below these values so that you receive alarms
only if your network is in poor health. The SMT Standard
recommended value is 8.
■
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
