7.6.2 Setting the Subnet Mask
The subnet mask defines how the SEHI treats SNMP Trap IP destination
addresses in its Trap Table.
• Set the subnet mask when workstations in the Trap Table reside on a
different subnet (i.e., across a gateway or router), and these
workstations are to receive SNMP traps.
• Use the subnet mask factory default setting of 0.0.0.0 when all trap
designated workstations are on the SEHI subnet.
Use the following steps to set the subnet mask:
1. Use the arrow keys to highlight the SubNET Mask field.
2. Enter the subnet mask into this field. The format for this entry is
XXX.XXX.XXX.XXX with values for XXX being from 0 to 255.
3. Press ENTER.
4. Use the arrow keys to highlight the SAVE option, then press ENTER
or F6. The “SAVED OK” message appears indicating that the changes
have been saved to memory.

The first time an attempt is made to exit the screen without

changes.
NOTE
Consult the Network Administrator prior to setting the Subnet
Mask.
