Setting conductor and XDAB priority

Introduction

You can use NWare to change the CobraNet Conductor and XDAB master priorities. These settings will ensure that a particular device within an XDAB cluster will become the XDAB master or that a particular CobraNet device on a network or VLAN segment will become a CobraNet Conductor.

Each NION will set the actual priority from within the range specified by the user. Each of these ranges can have two values.

If you want a NION to be an XDAB master or a CobraNet Conductor, set the appropriate range to be higher than any other device in the cluster.

Notes:

• NWare will normally ensure that the default values are set for proper operation. However, it may be necessary to manually adjust the settings in order to meet the constraints outlined in the use cases.
• Be aware of the Conductor priority settings of devices outside the XDAB cluster that reside elsewhere on the network. This point is important when using slave VLANs in order to ensure that a slave device within a cluster remains the CobraNet Conductor.

Tips:

• Explicitly set the CobraNet Conductor priority and XDAB master priority in all devices to ensure they operate correctly.
• Locate the CobraNet Conductor outside an XDAB cluster when possible.
• Set all Conductor priorities to 0 in all devices except those that should be allowed to be Conductors. For those devices that should be Conductors, make their priorities the same.
• Devices with CM-1 modules are preferred as Conductors over devices that have CM-2 modules.
