The problem is that only the master firewall sends device status traps to the syslog center. This happens although both firewall have the info-center configuration applied. the info-center configuration was applied to the slave firewall via HRP auto-sync feature.
No handling needed because this situation is normal, according to the normal operation of the device.
The cause of this issue is that in a Dual-system Hot-standby scenario the slave firewall cannot send any packets other than HRP control messages. This is why only the master firewall will record logging information to the syslog server via info-center.
