ϖNote: The IP Bridging radio button will be grayed out unless bridging has been turned on globally for the device using the Main Bridging Configuration Dialog Box (under Global/Bridging) and locally on this interface using the Bridging: Ethernet Dialog Box (under Ethernet/Bridging).
•If set to IP Off, then any IP packets received on this interface are discarded.
>IP Address
Every network interface on an IP internetwork must have a unique IP address that identifies that interface to other devices on the internetwork. Part of this address identifies the network segment the router interface is connected to, and the remainder uniquely identifies the router interface itself.
This address should be entered as four decimal numbers separated by periods
ϖ Note: The single most common problem encountered in IP networking is the use of a duplicate IP address. You must carefully track the network numbers you have assigned to various devices in order to avoid
>Network IP Subnet Mask
Most IP networks use “subnetting” in order to subdivide a large network into smaller logical
There are three generally used “classes” of subnetted IP networks: A, B and C. Each class uses a different amount of the IP address for the network and host portions. These classes may also be further divided by correctly setting the subnet mask.
If you do not enter a number in the Subnet Mask field, CompatiView will derive a default value from the IP Address number you entered just above. This default assumes you want a single subnet for all of the available host addresses. You must manually set the field if you want to further divide the address range.
To have CompatiView calculate a default mask, make sure that the Subnet Mask field is empty, position the cursor in the IP Address field, then just tab through the Subnet Mask field.
>Network IP Broadcast Address
The router will use this address to send any IP broadcast messages. The stan- dard broadcast address is all 255’s (hexadecimal FFs) in the host portion of
