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.
