The lerAlarm attribute is the link error rate (LER) value at which a link
connection generates an alarm. If the LER is greater than the alarm setting,
then SMT sends an SRF to the network manager indicating that there is a
problem with a port. The lerAlarm value is expressed as an exponent (such
-10
as 1 x 10 ). A healthy network would have an LER exponent of 1 x 10
-15
to 1 x 10 . You should set the lerAlarm below these values so that you
are only receiving alarms if your network is in poor health. The SMT
Standard recommended value is 8.
The lerAlarm value must be higher than the lerCutoff value so that the
network manager will be made aware of a problem before the PHY (port) is
actually removed from the network.
To set lerAlarm:
1 From the top level of the Administration Console, enter:
fddi port lerAlarm
You are prompted for a slot related to the FDDI port.
2 Enter the slot(s).
You are prompted for a port and an estimated link error rate at which the
link connection will generate an alarm.
3 Enter the port.
4 Enter the estimated link error rate value.
Valid exponent values are -4 through -15. Although these are negative
exponents, you should enter the value without the negative symbol. For
