SNMP traps
SNMP traps
5620 SAM listens to SNMP traps to receive changes from the network elements. 5620
SAM configures the trap log ID on each network element when it is first discovered. The
network element then uses that trap log ID to send all configuration changes and updates
to 5620 SAM. 5620 SAM will react to the traps it receives and make appropriate changes
to the database, alarms and related object as required.
SNMP trap sequence verification
SNMP trap sequence verification
5620 SAM retrieves the last trap sequence number sent from all network elements at a
configurable interval. This interval is configurable on a per resource group basis.
Resource groups allow the user to configure the communications behavior of a group of
network elements. By default, the core resource group includes all network elements, and
verifies the trap sequence number every 4 minutes. 5620 SAM compares that sequence
number with the sequence number of the last trap it received from that network element.
If they do not match, 5620 SAM will request only the missing traps from the network
element. If at any point 5620 SAM realizes that it is missing more than 200 traps from a
network element, or if the network element no longer has the missed trap, SAM will
request a full resynchronization on that network element rather than just request the
missing traps.
This behavior occurs by default and is not configurable.
Scheduled SNMP MIB polling
Scheduled SNMP MIB polling
5620 SAM can poll all data SNMP MIBs from the network elements at a configurable
interval. Starting in 5620 SAM Release 7.0 R1, the Polling Policy is disabled by default.
This behavior is configurable via the Polling tab of the Network Elements properties
form.
