Managed Switch CLI Manual, Release 8.0 Term Definition Tunnel ID The tunnel identification number. Interface The name of the tunnel interface. Tunnel Mode The tunnel mode. Source Address The source transport address of the tunnel. Destination Address The destination transport address of the tunnel. If you specify a tunnel ID, the command shows the following information for the tunnel: Term Interface Link Status MTU Size IPv6 Prefix is Definition Shows whether the link is up or down. The maximum transmission unit for packets on the interface. If you enable IPv6 on the interface and assign an address, the IPv6 address and prefix display. Loopback Interface Commands The commands in this section describe how to create, delete, and manage loopback interfaces. A loopback interface is always expected to be up. This interface can provide the source address for sent packets and can receive both local and remote packets. The loopback interface is typically used by routing protocols. To assign an IP address to the loopback interface, see "ip address" on page 4-9. To assign an IPv6 address to the loopback interface, see "ipv6 address" on page 7-12. interface loopback Use this command to enter the Interface Config mode for a loopback interface. The range of the loopback ID is 0 to 7. Format Mode interface loopback Global Config IPv6 Commands 7-8 v1.0, July 2009
