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.

5.15.3 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
