Standard SNMP Traps on EX Series Ethernet Switches

Apart from the standard SNMP traps listed in the preceding sections, Junos OS also supports the following standard traps on the EX Series Ethernet Switches:

• ptopoConfigChange—Generated when the value of ptopoLastChangeTime changes. Enables a network management system to trigger physical topology table maintenance polls. (RFC 2622, PTOPO MIB)
• pethPsePortOnOffNotification—Generated when the power supply status of a PSE port changes. Indicates whether the PSE port is supplying power to the PD port or not. (RFC 3621, Power Ethernet MIB)
• pethMainPowerUsageOnNotification—Generated when the PSE threshold indicator is on (RFC 3621, Power Ethernet MIB).
• pethMainPowerUsageOffNotification—Generated when the PSE threshold indicator is off (RFC 3621, Power Ethernet MIB).
