fddi port lerCutoff 243

Sets the link error rate estimate at which a link connection is disabled. When the lerCutoff value is reached, the PHY that detected a problem is disabled.

Valid Minimum Abbreviation

fd po lerC

Important Considerations

The lerCutoff value must be lower than the lerAlarm value so that the network management software is alerted to a problem before the PHY (port) is actually removed from the network.

Set the lerCutoff below these values so that a port is removed only as a last resort. The SMT Standard recommended value is 7.

The lerCutoff value is expressed as an exponent (such as 1 x 10-10). A healthy network has an LER exponent between 1 x 10-10and 1 x 10-15.

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.
