8.3.8.4 The Spectrum Management Master / Slave Relationship
By default Spectrum Management operates in a master / slave relationship. The master is
assumed to be the link master configured during installation. All Spectrum Management
configuration changes MUST be performed from the master. To enforce this, the Spectrum
Management web page has a different appearance depending if you are viewing the data
from the master or slave.
Figure 56 shows a sample Spectrum Management web page as seen from the master.
All configuration changes are applied at the master only. These changes are then messaged
from the master to the slave. Any Spectrum Management configuration messages received at
the slave are stored in non-volatile memory. This enables both master and slave to keep
identical copies of Spectrum Management configuration data in their non-volatile memories. It
is therefore possible to swap master and slave roles on an active point-to-point link without
modifying Spectrum Management configuration.
