The Conﬁguration Screen

IP Address

Displays the IP address of the SEHI.

SubNET Mask

Displays the subnet mask for the SEHI. A subnet mask is a 32-bit quantity which “masks out” the network bits of the IP address. This is done 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.

MAC Address

Displays the physical address associated with the interface.

Default Gateway

Displays the default gateway for the SEHI. This ﬁeld is not deﬁned until an appropriate value is entered. The default gateway identiﬁes the default gateway device that will forward packets to other IP subnetworks.

Serial Port 1 Application

Displays the port’s application setting as CONSOLE.

Baud Rate

Displays the Baud Rate setting of the device attached to the SEHI through the serial port. The setting for the serial port is 9600.

Port Enable Override

This command lets the user override the Disable Port settings in the Device Statistics screen to enable all ports in the stack.
