Master Settings
This menu item is only found on slave CC2000 servers. It is used under the
following conditions:
If the master’s IP address changes.
If the slave is offline at the time the master’s CC Port or HTTPS port
changes.
If the slave is offline at the time that a different CC2000 is promoted from
slave to master.
When these situations occur, there is no need to go through the
Register
procedure again (see
, page 140), in order to maintain the master/slave
connection. The administrator can use this page to update the information
accordingly.
To maintain the connection, simply key in the new IP address and/or port
settings, then click
Save
.
Note:
1. Since the IP address change is made at the OS level (not the CC2000
service level), the CC2000 system is unaware of the change.
Therefore master can’t change this information on the slaves
automatically. It must be done manually on all slaves.
2. Any CC2000 slave that is offline can’t be automatically notified at the
time of change, therefore this procedure must be performed at the
time the slave comes back on line.
3. This procedure allows any changes in the database that occurred
when the slave was not in communication with the master to be
merged into a common database. This is preferable for CC2000s that
were originally part of the same system but temporarily lost
communication with each other, since if the slave were to Register
anew with the master, it would lose any database information it added
while they were separated and take on the database information of the
master.
