IP Addressing
5-2 7112-A2-GB20-20 March 1998
IP Addressing Examples
Management of IP addressing is based on individual IP addresses assigned to
each interface. The IP interfaces for the unit are:
H Ethernet port – See Table A-5, Ethernet Port Options .
H
FDL – See Table A-2, Network Interface Options .
NOTE:
Do not assign IP addresses without the assistance of the network manager or
individuals responsible for determining the IP addressing scheme for your
organization.
The following examples apply to IP (SNMP) management traffic only. The subnet
mask shown for these examples is 255.255.255.000.
Local Addressing Only (No FDL)
In the following example, the DSU/CSUs do not use the FDL for management
communications. This can be the result of using Fractional T1 service or Frame
Relay Service. In this example both DSU/CSUs:
H
Only receive management data through the 10BaseT port connection.
H
Do not route the data between themselves. Routers route the management
data for the connected DSU/CSUs using the user data path between the
routers.
The following illustration shows each DSU/CSU with its own IP address on the
LAN subnet.
