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)# ip address 10.45.6.1 255.255.255.0
You also can enter the IP address and mask in CIDR format, as follows:
Brocade# ip address 10.45.6.1/24
Syntax: [no] ip address ip-addr ip-mask or ip-addr/mask-bits
Assigning an IP address to a loopback interface
Loopback interfaces are always up, regardless of the states of physical interfaces. They can add
stability to the network because they are not subject to route flap problems that can occur due to
unstable links between a Layer 3 device and other devices. You can configure up to four loopback
interfaces on a Layer 3 device.
You can add up to 24 IP addresses to each loopback interface.
NOTE
If you configure the device to use a loopback interface to communicate with a BGP4 neighbor, you
must also configure a loopback interface on the neighbor and configure the neighbor to use that
loopback interface to communicate with the Brocade device.
To add a loopback interface, enter commands such as those shown in the following example:
Brocade(config)# exit
Brocade(config)# interface loopback 1
Brocade(config)# ip address 10.0.0.1/24
Syntax: interface loopback num
The num parameter specifies the virtual interface number. You can specify from 1 through the
maximum number of virtual interfaces supported on the device. To display the maximum number
of virtual interfaces supported on the device, enter the show default values command.
Assigning an IP address to a virtual routing interface
A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) configured on a
Layer 3 device. You can configure routing parameters on the virtual interface to enable the Layer 3
device to route protocol traffic from one Layer 3 VLAN to the other, without using an external router.
NOTE
The device uses the lowest MAC address on the device (the MAC address of port 1 or 1/1/1) as the
MAC address for all ports within all virtual interfaces you configure on the device.
Enter commands similar to the following to add a virtual interface to a VLAN and configure an IP
address on the interface.
Brocade(config)# vlan 2 name IP-Subnet_10.1.2.1/24
Brocade(config-vlan-2)# untag 1/1/1 to 1/1/4
Brocade(config-vlan-2)# router-interface ve1
Brocade(config-vlan-2)# interface ve1
Brocade(config-vif-1)# ip address 10.1.2.1/24
