Subnet Mask (Modifiable)
Displays the subnet mask for the chassis. A subnet mask “masks out” the
network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the
network or subnetwork address, or to 0 if the corresponding bit identifies
the host. The 6C105 chassis automatically uses the default subnet mask
that corresponds to the IP class that was entered in the IP address field.
Chassis Date (Modifiable)
Contains a value that the chassis recognizes as the current date. When the
chassis date is modified and saved all interface modules installed in the
chassis are set to this date. To set a new chassis date, refer to
Section 5.7.3 .
Chassis Time (Modifiable)
Contains a value that the chassis recognizes as the current time. When the
chassis time is modified and saved, all interface modules installed in the
chassis are set to this time. To enter a new time, refer to
Section 5.7.4 .
Screen Refresh Time (Modifiable)
Contains the rate at which the LM screens are updated. This setting
determines how frequently (in seconds) information is updated on the
screen. To enter a new update time, refer to
Section 5.7.5 .
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 to the
default value. Refer to your Release Notes to ensure that the
Subnet Mask is a modifiable field.
