The Spectrum Management Master / Slave Relationship - Motorola PTP 300 Series User Manual

7.9.4 The Spectrum Management Master / Slave Relationship

The 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.
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.
Figure 71 shows an example Spectrum Management webpage as seen from the master.
Figure 72 shows an example Spectrum Management webpage as seen from the slave. It
should be noted that the key configuration attributes are not available on the slave web page.
NOTE
These examples are for 15 MHz operation; other channel bandwidths are similar. The
width of the vertical green bar represents the channel width.
