10.3.3.1 Master SNMP Destination
This menu item enables the Supervisor to set a NMS destination as master.
Select from the pull-down menu.
Select None if SNMP connection is by dial-out or no trap recovery (after network block out) is required.
This is the default to be backward compatible with legacy CXC trap notification method.
10.3.3.2 Inform Settings (Trap Acknowledge)
INFORM is similar to a Trap message; it has a response from the Network Management Software (NMS)
to the SNMP Agent.
The Master Destination is a mechanism that was implemented to secure communications to an NMS by
ensuring that a certain number of Traps reach their destinations.
INFORM no longer needs the Master Destination item but requires a response from the NMS or it will
retry the message.
NOTE
: These items are exclusive to one another. If only INFORMS are used, do not set a Master Desti-
nation.
