5. Use the arrow keys to highlight the YES command, then press ENTER. The changes are saved

and the module reboots.

5.2.2 Setting the Subnet Mask

If the management workstation that is to receive SNMP traps from the switch module is located on

a separate subnet, the subnet mask for the switch module may need to be changed from its default

value.

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.
