Configuring IP addresses

3

Syntax: [no] ip address ip-addr/mask-bits [secondary]

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 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.

Brocade(config)# interface ethernet 1/1/1

Brocade(config-if-1/1/1)# ip address 192.168.0.0 255.255.255.0

NOTE

You also can enter the IP address and mask in CIDR format, as follows:

Brocade(config-if-1/1/1)# ip address 192.168.0.0/24

Syntax: [no] ip address ip-addr ip-mask

or

Syntax: [no] ip address ip-addr/mask-bits
