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
You also can enter the IP address and mask in CIDR format, as follows:
device(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
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 switch and other devices. You can configure up to four loopback
interfaces on a Layer 3 switch.
You can add up to 24 IP addresses to each loopback interface.
To add a loopback interface, enter commands such as those shown in the following example:
device(config)# interface loopback 1
device(config-lbif-1)# ip address 192.168.0.0/24
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
switch. You can configure routing parameters on the virtual interface to enable the Layer 3 switch to
route protocol traffic from one Layer 3 VLAN to the other, without using an external router.
NOTE
The switch 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.
device(config)# vlan 2 name IP-Subnet_1.1.2.1/24
device(config-vlan-2)# untag 1/1/1 to 1/1/4
device(config-vlan-2)# router-interface ve1
device(config-vlan-2)# interface ve1
device(config-vif-1)# ip address 1.1.2.1/24
The first two commands in this example create a Layer 3 protocol-based VLAN named "IP-
Subnet_1.1.2.1/24" and add a range of untagged ports to the VLAN. The router-interface command
creates virtual interface 1 as the routing interface for the VLAN. The last two commands change to the
interface configuration level for the virtual interface and assign an IP address to the interface.
