Editing FDDI Port Attributes
Port attributes report the connection capabilities of a FDDI port, including the link
error rate (LER).
A status report frame (SRF) can contain link error monitor (LEM) status
indicating the number of times that a link has been rejected. This is used to keep
track of the link error rate (LER).
You can configure the LER by:
• Specifying the LER Cutoff
• Specifying the LER Alarm
Specifying the LER Cutoff
The LER cutoff is an estimate at which a link connection will be broken. The LER
cutoff ranges from 10
-4
to 101
-5
and is reported as the absolute value of the base 10
logarithm. By default, the LER cutoff is 10
-7
.
You can specify the LER cutoff only by using Site Manager.
