Configuring IP addresses
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.
Brocade(config)# enable port-config-password mustang
Brocade(config)# enable read-only-password mustang
NOTE
If you forget your super-user password, see the <Italic>Multi-Service IronWare Software Release 06.0.000 for Brocade
MLX Series and Brocade NetIron Family.
Syntax: enable | super-user-password | read-only-password | port-config-password <text>
The text for the read-only--password and the port-config password should be different from the text for the super-user
password. Passwords can be up to 48 characters long.
Configuring IP addresses
Brocade routers implement separate data and control planes. This architecture affects how you assign IP addresses. Table 29 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.
Support of subnet masks
Brocade routers support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing
(CIDR) network prefix masks.
• Enter a classical network mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.
• 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.
Assigning an IP address to a management interface
Instead of assigning a global IP address to the router for system management purposes, you must assign an IP address to the active
management module. If the active management module becomes unavailable and the redundant module becomes the active module,
the IP address is automatically assigned to the new active management module.
TABLE 29 Interfaces that can be given IP addresses
Interface Associated physical port Out of band or In
band
Management interface Ethernet 10/100/1000 port on active or
redundant management module
Out of band
Any interface over which user packets are
routed
Any interface module port In band
Any virtual interface over which user
packets are routed
Any interface port In band
Loopback interface – In band
