Chapter 6 - Using XDAB clusters with VLANs and CobraNet

Scenario 9 - Network with VLAN and three XDAB clusters
In this scenario, there are three VLANs, three XDAB clusters and no cluster contains all three
VLANs.
In cluster 1, VLAN 1 contains the XDAB master.
In cluster 1, VLAN 2 receives its clock from XDAB and is therefore in sync with VLAN 1.
In cluster 2, VLAN 1 is the XDAB master and receives its clock from the VLAN 1
Conductor in cluster 1.
In cluster 2, VLAN 3 receives its clock from XDAB. This clock is derived from the
Conductor of VLAN 1.
In cluster 2, one of the devices in VLAN 3 is the Conductor for VLAN 3.
In cluster 3, VLAN 3 is the XDAB master and receives its clock from the Conductor in
VLAN 3 in cluster 2.
In cluster 3, VLAN 2 is receiving its clock from the XDAB master in VLAN 3.
All Conductors in this topology are ultimately deriving their clocks from the Conductor
and XDAB master in VLAN 1 of cluster 1. So all clocks in this network in all three
VLANs will be in sync. No clock conflicts will exist.
Setting conductor and XDAB priority in NWare
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.
