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 10-10and 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.
