5.15.2 Setting the Subnet Mask
If the management workstation that is to receive SNMP traps from the
DLE2X-MA and DLE3X-MA is located on a separate subnet, the subnet
mask for the DLE2X-MA and DLE3X-MA must be changed from its
default.
To change the subnet mask from its default, perform the following steps:
1. Use the arrow keys to highlight the Subnet Mask field.
2. Enter the subnet mask into this field using Decimal Dotted Notation
(DDN) format.
For example: 255.255.255.0
3. Press ENTER. If the subnet mask is valid, the cursor returns to the
beginning of the Subnet Mask field. If the entry is not valid, the Event
Message Line displays “INVALID SUBNET MASK OR FORMAT
ENTERED”. Local Management does not alter the current value, but
it does refresh the Subnet Mask field with the previous value.
4. Use the arrow keys to highlight the SAVE command, then press
ENTER. The warning screen shown in Figure 5-18 displays.
5. Use the arrow keys to highlight the YES command and press ENTER.

5.15.3 Setting the Default Gateway
If the SNMP management station is located on a different IP subnet than
the DLE2X-MA and DLE3X-MA, a default gateway must be specified.
When an SNMP Trap is generated, the DLE2X-MA and DLE3X-MA
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
