3. Press ENTER. If the IP address is a valid format, the cursor returns to
the beginning of the IP address field. If the entry is not valid, the Event
Message Line displays “INVALID IP ADDRESS OR FORMAT
ENTERED”. Local Management does not alter the current value and
refreshes the IP address field with the previous value.
4. Use the arrow keys to highlight the SAVE command, then press
ENTER. The “SAVED OK” message displays indicating that the

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.
