Installation guide

3. Access the configuration level of the CLI by entering the following command.
device# configure terminal
device(config)#
4. Configure the IP addresses and mask addresses for the interfaces on the router.
device(config)# interface e 1/1/1
device(config)# ip address 192.168.0.0 255.255.255.0
NOTE
You can use the ip address ip-addr /mask-bits command if you know the subnet mask length. In
the example in step 4, you could enter ip address 192.168.0.0/24.
Use the secondary parameter if you have already configured an IP address within the same subnet
on the interface.
Configuring IP parameters for devices running Layer 3 software
This section describes how to configure IP parameters for devices running Layer 3 software.
Configuring IP addresses
You can configure an IP address on the following types of Layer 3 switch interfaces:
• Ethernet port
• Virtual routing interface (also called a Virtual Ethernet or "VE")
• Loopback interface
By default, you can have up to 24 IP addresses on each interface, but you can increase this number to
128 IP addresses.
NOTE
Once you configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface
parameters on individual ports in the VLAN. Instead, you must configure the parameters on the virtual
routing interface itself.
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 IP 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 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 bits (ones).
By default, the CLI displays network masks in classical IP address format (for example,
255.255.255.0). You can change the display to prefix format.
Assigning an IP address to an Ethernet port
Enter the following commands to assign an IP address to port 1/1/1.
device(config)# interface ethernet 1/1/1
device(config-if-1/1/1)# ip address 192.168.0.0 255.255.255.0
