To do...

Use the command...

Remarks

Enable the error symbol period

alarm function

alarm oam error-symbol-period

enable

Optional

The system generates an error

symbol period alarm when the

number of error frames in a

specific period (that is, the window

size) exceeds the corresponding

predefined threshold.

By default, this function is enabled.

Configure the window size and

thresholds for error symbol period

alarms

alarm oam error-symbol-period

{ window-high windowhigh |

window-low windowlow

|

threshold-high thresholdhigh

|

threshold-low thresholdlow

} *

Optional

When both the upper limit and the

lower limit of the alarm threshold

are set to 0, a lot of alarms are

generated immediately. Since

alarm events are carried in the

OAM packets, a lot of OAM

packets are generated. In this

case, OAM packets may be lost.

The window size and threshold

values specified in this command

comprise two parts, a significant

part and an insignificant part, both

16 bits in length.

By default, the window size is 1

second, and the alarm threshold is

20 bytes.

Enable the local link fault alarm

function

alarm oam local-link-fault

enable

Optional

The system generates a local link

fault alarm when the inbound

direction of the local data terminal

becomes faulty.

Enable the registration error alarm

function

alarm registration-error enable

Optional

The system generates a

registration error alarm when an

error occurs during the registration

of an ONU.

By default, this function is enabled.
