5.7.2Setting the Subnet Mask

If the management workstation that is to receive SNMP traps from the 2H23-50R or 2H33-37R is located on a separate subnet, the subnet mask for the 2H23-50R or 2H33-37R may need to 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 Dotted Decimal Notation (DDN) format.

For example: 255.255.0.0

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 screen displays the message “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 5-11displays.
