Figure 26: Set IP address of Trap Receiver
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.
