Configuring IP addresses

DRAFT: BROCADE CONFIDENTIAL
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.
For devices in an IronStack, you will need to configure a common IP address for the entire stack.
For information about how to do this, see the FastIron Configuration Guide.
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.
Follow the steps below:
• 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 FastIron Configuration
Guide.
Devices running layer 2 software
Follow the steps below to configure an IP address on a device running Layer 2 software.
1. At the opening CLI prompt, enter enable.
FLS648 Switch> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, FLS648
Switch#), then press Enter. This command erases the factory test configuration if it is still
present:
FLS648 Switch# 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:
FLS648 Switch# configure terminal Privileged EXEC Level
FLS648 Switch(config)# Global config Level
4. Configure the IP address and mask for the device.
FLS648 Switch(config)# ip address 192.22.3.44 255.255.255.0
5. Set a default gateway address for the device.
FLS648 Switch(config)# ip default-gateway 192.22.3.1
NOTE
You do not need to assign a default gateway address for single subnet networks.
