Information in this document applies to any platform.
The Solaris 11 Net-SNMP Agent, snmpd, controlled by the net-snmp SMF service, is configured to generate network interface link down and up traps by having the following in the /etc/net-snmp/snmp/snmpd.conf file:
notificationEvent linkUpTrap linkUp ifIndex ifAdminStatus ifOperStatus
notificationEvent linkDownTrap linkDown ifIndex ifAdminStatus ifOperStatus
monitor -r 60 -e linkUpTrap "Generate linkUp" ifOperStatus != 2
monitor -r 60 -e linkDownTrap "Generate linkDown" ifOperStatus == 2
A DLMP interface is configured for a aggregation, named dlmp0 for example, and it consists of interfaces named net0 and net1 for physical interfaces. When the net0 interface fails, no SNMP link down trap, is generated. In this scenario the DLMP interface dlmp0 still is fully operational due to the other interface, net1, still being up and active. A trap would not be generated until the second interface, net1 loss its link resulting in the dlmp0' status changing to down.
