Configuring the Cluster Configuration and Control Feature

Creating a Cluster Secret 13-5

 Select a unit with the highest density port count in the

cluster to be your master, because if you have varying port

density units in your cluster, the number of ports

information to be shared will be the lowest common

denominator. For example, if you have a 2-port unit, and

you share ALL ports configurations and send it to the

cluster containing 48 port units, only ports 1 and 2 will be

shared to the cluster. If to make sure all the ports are

shared, make a 48 port unit the master, then make the

changes, and then share them to the cluster. All 48 ports

will be sent, but ports 1 and 2 will be the only ones looked

at by a 2-port unit.

X To access Cluster Configuration and Control

Type the following command in Configuration

Command Mode:

Example Config:0 >>cluster

Creating a Cluster Secret

The secret allows authorized LX units access to other LX units

with the same secret. The secret should be at least 16

characters long. The maximum is 32 characters. All nodes in the

cluster must be configured with the same secret if they are to

communicate. You must set up the secret individually on each

LX unit.

L Your cluster secret must be kept secret if future

cluster operations are to be performed securely. This

implies that you should configure your cluster secret

locally, or via a secure protocol such as SSH.

X To set up the secret at the Quick Configuration Menu

1. Plug in the terminal at the DIAG port (port 0 - port values

are 9600 bps, eight data bits, one stop bit, no parity, and

Xon/Xoff flow control).
