IBM 4002-C4A, Installation And User Manual, Page: 48 / 94

Note: You must set the super-user password before you can set other types of
passwords.
4. Enter the following commands to set the port configuration and read-only
passwords:
NetIron(config)# enable port-config-password <text>
NetIron(config)# enable read-only-password <text>
Note: If you forget your super-user password, see the Release Notes.
Syntax:
enable super-user-password | read-only-password |
port-config-password <text>
Passwords can be up to 48 characters long.
Configuring IP addresses
The switches implement separate data and control planes. This architecture affects
how you assign IP addresses. Table 6 outlines the interfaces to which you can
assign IP addresses.
In this table, “in band” refers to an interface over which user packets are routed,
while “out of band” refers to an interface over which control packets related to
system management are forwarded.
Table 6. Assigning IP addresses
Interface Associated physical port Out of band/In band
Management interface Single 10/100/1000 Mbps Ethernet
management port Out of band
Any interface over which user
packets are routed Any network interface port In band
Any virtual interface over
which user packets are
routed Any interface port In band
Loopback interface – In band

How to assign an IP address to an interface or virtual interface over which user
packets are routed
Support of sub-net masks
The B48C and B50C support both classical IP network masks (Class A, B, and C
sub-net masks, and so on) and Classless Interdomain Routing (CIDR) network
prefix masks.
v
To enter a classical network mask, enter the mask in IP address format. For
example, enter “209.157.22.99 255.255.255.0” for an IP address with a Class-C
sub-net mask.
v To enter a prefix number for a network mask, enter a forward slash ( / ) and the
number of bits in the mask immediately after the IP address. For example, enter
“209.157.22.99/24” for an IP address that has a network mask with 24 significant
(“mask”) bits.
