Hot Backup - Polycom RMX 1500 Administrator's Manual

Hot Backup

15 To specifically define one or more valid terminals, ensure that the
Accept SNMP Packets from any Host option is cleared and then click the
Add button.
The Accepted Host IP Address dialog box opens.
16 Enter the IP Address of the Manager terminal from which valid
queries may be sent to the MCU, and then click OK.
Click the Add button to define additional IP Addresses.
The IP Address or Addresses are displayed in the Accept SNMP Packets
from These Hosts box.
Queries sent from terminals not listed in the Accept SNMP Packets from These
Hosts box are regarded as a violation of the MCU security, and if the Send
Authentication Trap check box is selected, an appropriate message will be sent
to all the terminals listed in the SNMP Properties – Traps dialog box.
17 In the RMX - SNMP Properties - Security dialog box, click OK.
Hot Backup implements a high availability and rapid recovery solution.
Two RMX's are configured in a Master/Slave relationship: the Master MCU
is active while the Slave acts as a passive, fully redundant Hot Backup of
the Master MCU.
All conferencing activities and configuration changes that do not require a
System Reset are mirrored on the Slave MCU five seconds after they occur
on the Master MCU.
In the event of failure of the Master MCU, the Slave MCU transparently
becomes active and assumes the activities and functions with the backed
up settings of the failed Master MCU.
