If the SNMP management station is located on a different IP subnet than the device, a default 
gateway must be specified. When an SNMP Trap is generated, the device sends out an ARP 
request to the default gateway, which responds with its MAC address. The device then sends the 
trap using the IP address from the Trap Table and the MAC address of the default gateway. To set 
the default gateway, perform the following steps:

1. Use the arrow keys to highlight the Default Gateway field.

2. Enter the IP address of the default gateway using the DDN format.

For example: nnn.nnn.nnn.nnn

3. Press ENTER. If the default gateway entered is in the correct format, the cursor returns to the 

beginning of the Default Gateway field. If the format is not correct, the screen displays 
“INVALID DEFAULT GATEWAY OR FORMAT ENTERED”. Local Management does not 
alter the current value, but it does refresh the Default Gateway field with the previous value.

4. Use the arrow keys to highlight the SAVE command.

5. Press ENTER. The message “SAVED OK” displays at the top of the screen.

If the network TFTP server is located on a different IP subnet than the device, a Gateway IP 
address should be specified. To set the TFTP Gateway IP address, perform the following steps:

1. Use the arrow keys to highlight the TFTP Gateway IP Addr field.

2. Enter the IP address of the TFTP gateway using the DDN format.

For example: nnn.nnn.nnn.nnn

3. Press ENTER. If the TFTP gateway IP address entered is a valid format, the cursor returns to the 

beginning of the TFTP Gateway IP Address field. If the entry is not valid, the screen displays 
“INVALID TFTP GATEWAY IP ADDRESS OR FORMAT ENTERED”. Local Management 
does not alter the current value, but it does refresh the TFTP Gateway IP Address field with the 
previous value.

4. Use the arrow keys to highlight the SAVE command.

5. Press ENTER. The message “SAVED OK” displays.
