Setting the Subnet Mask
Note: Consult your Network Administrator prior to setting the Subnet
Mask.
The Subnet Mask defines how your TRXI treats SNMP Trap IP
destination addresses in its Community Names table.
• Set the Subnet Mask when workstations in the Community
Names table reside on a different subnet (i.e., across a gateway
or router), and you want these workstations to receive traps.
• Use the Subnet Mask factory default setting of 0.0.0.0 when all
trap designated workstations are on the TRXI subnet.
To set the Subnet Mask:
1. Use the arrow keys to highlight the Subnet Mask field.
2. Press Return to clear the field.
3. Enter the Subnet Mask into the field. The format for this entry is
XXX.XXX.XXX.XXX, with values of XXX ranging from 0-255.
4. Press Return. If the format is not valid, the “INVALID IP
FORMAT” message appears. Re-enter the Subnet Mask using the
correct format.
5. If the format is correct, use the arrow keys to highlight the SAVE
command at the bottom of the screen.
6. Press Return. The “SAVED” message appears on the screen
indicating that your changes have been saved to memory.
Setting the Clear SNMP Agent IP Address and Community
Names Only Field
