Configuring IP addresses
You must configure at least one IP address using the serial connection to the CLI before you can
manage the system using the other management interfaces.
Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on)
and Classless Interdomain Routing (CIDR) network prefix masks.
• To enter a classical network mask, enter the mask in IP address format. For example, enter
"10.157.22.99 255.255.255.0" 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.
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0).
You can change the display to the prefix format. See the FastIron Ethernet Switch Administration Guide.
Devices running Layer 2 software
Use the following procedure to configure an IP Address on a device running Layer 2 software.
1. At the opening CLI prompt, enter enable .
device> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, Brocade# ), then
press Enter . This command erases the factory test configuration if still present:
device# erase startup-config
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 do 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 following command:
device# configure terminal
(Privileged EXEC Level)
device(config)# (Global CONFIG Level)
4. Configure the IP address and mask for the switch.
device(config)# ip address 10.22.3.44 255.255.255.0
5. Set a default gateway address for the switch.
device(config)# ip default-gateway 10.22.3.1
NOTE
You do not need to assign a default gateway address for single subnet networks.
