NOTE: The default loopback interface (lo0) with IP address 127.0.0.1 is not displayed in the
show ip command output because it is permanently configured on the switch. To display the default
loopback address, enter the show ip route command as shown in the example below.
To display the loopback interfaces configured on the switch in a list of IP routing entries displayed
according to destination IP address, enter the show ip route command.
The following example displays the configuration of the default loopback interface (lo0) and one
user-defined loopback interface (lo2).

IP Preserve: retaining VLAN-1 IP addressing across configuration file
downloads
For the switches covered in this guide, IP Preserve enables you to copy a configuration file to
multiple switches while retaining the individual IP address and subnet mask on VLAN 1 in each
switch, and the Gateway IP address assigned to the switch. This enables you to distribute the same
configuration file to multiple switches without overwriting their individual IP addresses.
