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
“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.
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 Brocade ICX 6650
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.
Brocade> enable
2. Enter the following command at the CLI Privileged EXEC level prompt, then press Enter. This
command erases the factory test configuration if still present:
Brocade# 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:
Brocade# configure terminalPrivileged EXEC Level
Brocade(config)# Global CONFIG Level
4. Configure the IP addresses and mask for the switch.
Brocade(config-if-e1000-2)# ip address 192.168.0.0 255.255.255.0
5. Set a default gateway address for the switch.
Brocade(config)# ip default-gateway 192.168.0.0
NOTE
You do not need to assign a default gateway address for single subnet networks.
