Configuring an Extended ECC Communication

You can establish extended ECC communication between two subracks without fiber connections through an Ethernet line. In this way, the U2000 Web LCT manages the equipment in a centralized manner.

Prerequisites

NEs are properly connected with crossover cables.

Context

NOTICE:

This operation may restore the settings of communication, and may interrupt services.

Procedure

In the NE Explorer, select an NE and choose Communication > ECC Management from the Function Tree.

Select the Extended ECC Mode.

If you set Extended ECC Mode to	Then
Auto mode	You need not set other parameters.
Specified mode	If the NE serves as the server, set Port in the Set Server. If the NE serves as the client, set Opposite IP and Port in the Set Client area. NOTE: Some NEs can be set as the server and client at the same time. If you need to set the NE as the server and client at the same time, the port number when the NE serves as the server cannot be duplicate with the port number when the NE serves as the client.
Autosensing mode	The Extended ECC Mode is changed to Auto mode when an NE is connected to NEs of earlier versions. In other cases, the extended ECC is disabled.

If you set Extended ECC Mode to

Then

Auto mode

You need not set other parameters.

Specified mode

If the NE serves as the server, set Port in the Set Server.

If the NE serves as the client, set Opposite IP and Port in the Set Client area.

NOTE:

Some NEs can be set as the server and client at the same time.
If you need to set the NE as the server and client at the same time, the port number when the NE serves as the server cannot be duplicate with the port number when the NE serves as the client.

Autosensing mode

The Extended ECC Mode is changed to Auto mode when an NE is connected to NEs of earlier versions. In other cases, the extended ECC is disabled.

NOTE:

Auto mode: Establish an extended ECC connection automatically. Though this mode is convenient, extra connections will be established and the resource availability is low. It is recommended when there are less than four NEs. No extended ECC can be established automatically unless both the NEs between which an extended ECC is to be established are set to the automatic mode.
Specified mode: Specifies that an extended ECC is to be established between the server and the client. The connection is highly reliable and the bandwidth availability is high. This mode is usually used to establish an extended ECC connection.
For an NE, the two modes cannot be used at the same time to extend ECC.

Click Apply and the Warning dialog box is displayed. Click OK.

Follow-up Procedure

After you complete the settings for one NE, you need to configure the settings for the opposite NE to enable the extended ECC communication. Note the following points:

If you set Extended ECC Mode to Auto mode for an NE, configure the same settings for the opposite NE.
If you set Extended ECC Mode to Specified mode for an NE, configure the same settings for the opposite NE. In addition, the roles of the two NEs must be different. That is, if an NE serves as the server, the opposite NE must be the client.
