Configuring IP addresses

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.
For example, to assign the IP address 10.0.1.1 to the management module, use these steps.
1. At the opening CLI prompt, enter enable.
Brocade> enable
2. Enter the erase startup-config command at the Privileged EXEC level prompt (for example,
Brocade#), then press Enter. This command erases the factory test configuration if it is still
present.
Brocade# erase startup-config
Syntax: erase startup-config
After entering this command, perform a reload on the system.
CAUTION
Use the erase startup-config command only for new systems. If you enter this command on a
system you have already configured, the command erases the configuration. If you accidentally
erase the configuration on a configured system, enter the write memory command to save the
running configuration to the startup-config file.
3. Access the configuration level of the CLI by entering the configure terminal command.
Brocade# configure terminal
Brocade(config)#
4. Configure the IP address and mask for the management interface by entering these
commands.
Brocade(config)# interface management 1
Brocade(config-if-mgmt-1)# ip address 10.0.1.1 255.255.255.0
Syntax: enable [<password>]
Syntax: configure terminal
Syntax: interface management <num>
Syntax: [no] ip address <ip-addr> <ip-mask>
