Operation:

Notiﬁcations occur whenever a port status is changed.

Connecting or disconnecting a powered device while the unit is “ON”, or turning portxCtr ON or OFF

will cause a SNMP Trap Ringer Console window to pop up displaying the change. Click an individual

trap event on the left side of the window, the detailed trap info will display on the right. Checking the

Pause checkbox will stop trap reporting and un-checking it resume trap reporting. To clear the Trap

Ringer Console, click the second icon from the left.

Notes:

If the TRAP receiver IP address is properly set but no notiﬁcations are received, a probable cause is

that the Windows Firewall is blocking the TRAP UDP Port 162. To open this TRAP port, execute:

Start » Control Panel » Windows Firewall » then select <Exceptions>. If the Firewall is ON, click <Add

Port…> button, check radio button <UDP>, enter a Name (for example: SNMP TRAP) and set the port

number as 162.

Also check any other ﬁrewall on your network that might be blocking the network trafﬁc on UDP Port

162.
