• How to assign an IP address to an interface or virtual interface over which user packets are routed
Support of sub-net masks
The devices support both classical IP network masks (Class A, B, and C sub-net masks, and so on) and
Classless Interdomain Routing (CIDR) network prefix masks.
The following sub-net masks are supported by the devices:
• 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 sub-net 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 device for system management purposes, you now
assign an IP address to the management interface. The IP address is assigned to the active
management module port. If the active management module becomes unavailable and the redundant
module becomes the active module, the IP address is assigned to the new active management module
port.
For example, to assign the IP address 10.0.1.1 to the management interface, do the following.
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
device(config)#
4. Configure the IP address and mask for the management interface by entering the following
commands.
device(config)# interface management 1
device(config-if-mgmt-1)# ip address 10.0.1.1 255.255.255.0
Syntax: enable [ password ]
Syntax: configure terminal
Syntax: interface management 1
Syntax: [no] ip address ip-addrip-mask
