TCP/IP address ranges
When you select a management console TCP/IP address, ensure that you do not
create a TCP/IP address conflict between your network and the 242x private
network.
Use the following guidelines to prevent an address conflict:
v The management console TCP/IP address that you select must not be in the
same address range as the address used by the 242x private networks.
v
The TCP/IP addresses used by the 242x private networks must be outside the
address ranges used by any network that the management console can reach.
v
The 242x private network has one default address range. If the default address
range cannot be used because it conflicts with another network, you can instead
specify one of three optional addresses ranges.
v The IBM service documentation can refer to the two private networks as "black"
and "gray" regardless of which address range has been assigned.
v
Table 69 and Table 70 on page 201 can help you determine the 242x private
network address range that the IBM service representative sets during the
installation.
Use Table 69 to determine whether the default address range can be used.
Table 69. Default TCP/IP address range determination
Question: If the answer is no... If the answer is yes...
Do any of your networks to be
reached by the management
console use either of these
address ranges:
v 172.16.0.0 to 172.16.255.255
(172.16.0.0/16)
v
172.17.0.0 to 172.17.255.255
(172.17.0.0/16)
There is not a potential address conflict.
The default 242x private network
address ranges can be used. In Table 68
on page 197, use the following
instructions:
1. In the MC1 or MC2 column of the
TCP/IP interface address row, as
appropriate, enter the IP address for
the management console.
2. In the MC1 or MC2 column of the
242x private network address
ranges
row, as appropriate, check
Yes.
There might be an address conflict
between your networks and the 242x
private networks.
Your service representative must
reconfigure the 242x private networks to
use one address range option from
Table 70 on page 201.
1. In Table 70 on page 201, select only
one address range option for the242x
private network that does not create a
potential address conflict.
2. In Table 68 on page 197, in the MC1
or MC2 column of the
242x private
networks address ranges row, as
appropriate, check the address range
option that you selected from
Table 70 on page 201.
If the default address range cannot be used, use one of the optional TCP/IP
address range options provided on Table 70 on page 201.
Note: The options in the table are listed from most preferable (Option 1) to least
preferable (Option 3).
