Press ENTER. If the IP address is a valid format, the cursor returns to

5.7.2
Setting the Subnet Mask
If the management workstation that is to receive SNMP traps from the 
6C105 is located on a separate subnet, the subnet mask for the 6C105 
must be changed from its default.
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 Decimal Dotted Notation 
(DDN) format. 
For example: 255.255.255.0
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 Event 
Message Line displays “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.
4.
Use the arrow keys to highlight the SAVE command, then press 
ENTER. The changes are saved to memory.
NOTE
When a valid IP address is assigned, the Subnet Mask field 
automatically enters the default mask that corresponds with 
class of IP entered in the IP Address field. Some firmware 
revisions do support changing the chassis subnet mask from 
the default value. Refer to your Release Notes to ensure that 
the Subnet Mask is a modifiable field.
