NOTE

The ﬁrst time an attempt is made to exit the screen without saving the changes, a “NOT SAVED?” message is displayed. The edits are lost if the user proceeds to exit without saving the changes.

7.6.2Setting the Subnet Mask

NOTE

Consult the Network Administrator prior to 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.
