Procedure 5-102: Clear "RPR Topology Inconsistency" condition

- Overview

This procedure is used to clear an RPR Topology Inconsistency condition.

- Before you begin

Prior to performing this procedure:

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

  2. Refer to Electrostatic discharge in Chapter 1, Safety.

  3. Obtain office records that show the correct RPR MAC addresses and required cross-connections for the ring.

Steps

Complete the following steps to clear the RPR Topology Inconsistency condition.

 
1

From the WaveStar® CIT System View, click the Alarm List button and locate the RPR Topology Inconsistency condition in the resulting alarm list and note the corresponding VCG AID.

2

From the System View, select View → Rings → Ring Map. Select the required RPR ring and click Select.

Result:

The RPR ring map information appears.

3

Observe the MAC Address of each node and Ringlet 0 (R0) and Ringlet 1 (R1) between each node.

4

Important!

Each LNW78 100/1G-FSR Gigabit Ethernet circuit pack must have a unique MAC address within the ring.

The ring must be bidirectionally symmetric with respect to the RPR MAC addresses as seen on Ringlet 0 and Ringlet 1.

If ...

Then ...

duplicate RPR MAC addresses exist within the ring,

Using the ring map and local procedures, identify and replace the duplicate LNW78 100/1G-FSR Gigabit Ethernet circuit pack.

Reference:

Procedure 6-9: Replace Ethernet/Data circuit pack

ring addresses are not bidirectionally symmetric,

Using local procedures and the Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) User Operations Guide, 365-372-325, reengineer the ring span(s) making sure that each span is connected bidirectionally to its neighbor.

5

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

If the RPR Topology Inconsistency condition is still present, contact your next level of support.
