3. Press the Return key. 

The new value appears in the IP Address field. 

4. If the IP Address is correct, highlight the SAVE command and then

The “SAVED” message appears on the screen indicating that your 
changes have been saved to memory.

The MicroMMAC-T will then do a soft reset.

Subnets are logical divisions of the network that serve to isolate groups of 
devices. The Subnet Mask determines how the MicroMMAC-T directs 
SNMP Trap messages (see Section 4.3.4 for information about SNMP 
Traps) to a destination address. The MicroMMAC-T directly addresses 
destinations within its own subnet. The MicroMMAC-T sends messages 
destined for other subnets to a router.

•

Use the Subnet Mask factory default setting, 0.0.0.0, when the 
workstations designated to receive trap messages exist within the same 
subnet as the MicroMMAC.

•

Set a new value for the Subnet Mask when workstations designated to 
receive traps reside on a different subnet (that is, across a gateway or 
router).

1. Highlight the Subnet Mask field.

2. Type the Subnet Mask into the field. The format for this entry is 

XXX.XXX.XXX.XXX, with values of XXX ranging from 0-255.

3. Press the Return key. 

If the format is not valid, the “INVALID IP FORMAT” message 
appears. Retype the Subnet Mask using the correct format.

4. If the format is correct, highlight the SAVE command and then press 

the Return key.
