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 monitoring (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 rate

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

To set the LER cutoff, complete the following tasks:
