Setting the Default Gateway
If the SNMP management station is located on a different IP subnet than 
the 6E12X-26 and 6E13X-25, a default gateway must be specified. When 
an SNMP Trap is generated, the 6E12X-26 and 6E13X-25 sends the Trap 
to 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: 134.141.79.121

Press ENTER. If the default gateway entered is a valid format, the 
cursor returns to the beginning of the Default Gateway field. If the 
entry is not valid, the Event Message Line 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.

Use the arrow keys to highlight the SAVE command.
