2.9 Configuring an IP Address
The switch ships with the default IP address 192.168.0.1/24. Connect via the serial port in order to assign the switch an IP address on your network.
The physical ports (or switchports) of the IC35516 are L2 ports, and cannot have an IP address assigned to them. By default, each switchport belongs to VLAN 1, a virtual interface (veth1) that may be assigned a primary, as well as any number of secondary, IP addresses. Use the following instructions to configure an IP address to the switch. The network administrator may later assign primary IP addresses to any other VLAN created.
Follow the steps below to change the switch’s IP address.
1.Connect to the console and press Enter at the Password prompt, as described above.
2.The screen will display the user mode prompt, Router>.
3.Type enable. The new prompt is Router#.
4.Type configure terminal. The new prompt is Router(config)#.
5.The default IP address is assigned to the veth1 interface. Type interface veth1. The new prompt is
Router(config-if-veth1)#.
6.Type ip address and the new address. Your screen will look like this example:
Router> enable
Router# configure terminal Router(config)# interface veth1
Router# show interface veth1 Veth1 is up, line protocol is up
Hardware is virtual interface VLAN 1, address is 00:00:94:D2:56:FA Encapsulation ARPA, Flags: <UP,BROADCAST,RUNNING,MULTICAST>

Router# write file
Writing
Configuration saved to
Router#
It is also acceptable to enter the subnet mask by typing ip address 192.168.123.254/24. Use the show interface veth1 command from privileged mode to see the new IP address. The new IP address automatically writes over the default IP address.
See Chapter 5 for more information on assigning IP addresses to interfaces.
2.9.1 Setting a Default IP Gateway Address
To define the default IP gateway for the switch, insert a static route:
Router(config)# ip route 0.0.0.0 255.255.255.255 <gateway IP> <mask>
