Procedure 5-55: Clear "inc. LAG" alarms

- Overview

This procedure is used to clear the following alarms:

  • inc. LAG Partial Link Loss

  • inc. LAG PLCF

  • inc. LAG Total Link Loss

- Before you begin

Prior to performing this procedure:

  1. Refer to Before you begin and Required equipment in this chapter.

  2. Refer to Laser safety and Electrostatic discharge in Chapter 1, Safety.

Steps

Complete the following steps to clear an inc. LAG alarm.

 
1

From the WaveStar® CIT System View, click the Alarm List button and locate the inc. LAG alarm in the resulting alarm list.


2

Refer to the Probable Cause column in the alarm list, determine the affected Link Aggregation Group, and note the corresponding AID.


3

Important!

A likely cause of the inc. LAG alarm is a transmission-related LAN port or socket alarm/standing condition associated with a member of the Link Aggregation Group.

Refer to the alarm list and note all LAN port and socket alarms/standing conditions associated with members of the specified Link Aggregation Group.


4

Proceed to the appropriate procedures to clear all LAN port and socket alarms/standing conditions associated with members of the specified Link Aggregation Group in order of severity.


5

From the System View, click the Alarm List button and click Refresh.


6

Is the inc. LAG alarm still present?

If...

Then...

Yes

Continue with the next step.

No

STOP! End of Procedure.


7

Visually check the local fiber connections between the affected circuit pack faceplate/pluggable transmission modules and the LGX panel or equivalent connection point to ensure that the LAN ports are properly connected.

If improper connections...

Then...

were found,

Follow local procedures to connect the LAN ports as required. Then continue with Step 8.

were not found,

Proceed to Step 10.


8

From the System View, click the Alarm List button and click Refresh.


9

Is the inc. LAG alarm still present?

If...

Then...

Yes

Continue with the next step.

No

STOP! End of Procedure.


10

Important!

A likely cause of the inc. LAG alarm at the local network element is a configuration conflict with the interfacing customer LAN port (LAG partner). The Link Aggregation Group and/or LAN port provisioning at the LAG partner is incompatible.

Follow local procedures to verify the Link Aggregation Group and/or LAN port provisioning at the interfacing customer LAN port (LAG partner). Does the LAG partner have Link Aggregation Control Protocol (LACP) enabled?

If...

Then...

Yes,

Proceed to Step 13.

No,

At the local node, select Configuration → Data → Create/Modify/Delete LA Group to access the required local Link Aggregation Group and provision the Protocol parameter to None to disable the Link Aggregation Control Protocol.

Continue with the next step.


11

From the System View, click the Alarm List button and click Refresh.


12

Is the inc. LAG alarm still present?

If...

Then...

Yes

Contact your next level of support.

No

STOP! End of Procedure.


13

At the local node, select View → Data → Virtual Switch to access the Virtual Switch associated with the required local Link Aggregation Group and determine the provisioned VLAN Tagging Mode (802.1TAG or Transparent).


14

If the provisioned VLAN Tagging Mode is...

Then...

802.1TAG,

Select View → Data → VLAN to access the assigned VLANs and verify that a VLAN is provisioned for the required Link Aggregation Group listed under Ethernet Port (Untagged).

If required, select Configuration → Data → Create VLAN to provision a VLAN for Untagged Traffic on the required Link Aggregation Group.

Transparent,

Select View → Data → Port Tag to access the assigned Port Tags and verify that a Port Tag is provisioned for the required Link Aggregation Group listed under Ethernet Port (Default Tag).

If required, select Configuration → Data → Create Port Tag to provision a Default Tag for the required Link Aggregation Group.


15

From the System View, click the Alarm List button and click Refresh.

If the inc. LAG alarm is still present, contact your next level of support.
