Displaying Tunnels Summary using the CLI Command For information about the CLI command that performs this function, see the following chapter in the CLI Reference Guide: • Tunnel Interface Commands Loopbacks The PowerConnect M6220/M6348/M8024 provides for the creation, deletion, and management of loopback interfaces. They are dynamic interfaces that are created and deleted through userconfiguration. The PowerConnect M6220/M6348/M8024 supports multiple loopback interfaces. A loopback interface is always expected to be up. As such, it provides a means to configure a stable IP address on the device that may be referred to by other switches. This interface provides the source address for sent packets and can receive both local and remote packets. It is typically used by routing protocols. The loopback does not behave like the network port on Switching systems. In particular, there are no neighbors on a loopback interface. It is a pseudo-device for assigning local addresses so that the router can be communicated with by this address, which is always up and can receive traffic from any of the existing active interfaces. Thus, given reachability from a remote client, the address of the loopback can be used to communicate with the router through various services such as telnet and SSH. In this way, the address on a loopback behaves identically to any of the local addresses of the router in terms of the processing of incoming packets. The Loopbacks menu page contains links to web pages that configure and display loopback parameters and data. To display this page, click Routing > Loopbacks in the tree view.

Loopbacks

The PowerConnect M6220/M6348/M8024 provides for the creation, deletion, and management of

loopback interfaces. They are dynamic interfaces that are created and deleted through user-

configuration. The PowerConnect M6220/M6348/M8024 supports multiple loopback interfaces.

A loopback interface is always expected to be up. As such, it provides a means to configure a stable IP

address on the device that may be referred to by other switches. This interface provides the source

address for sent packets and can receive both local and remote packets. It is typically used by routing

protocols.

The loopback does not behave like the network port on Switching systems. In particular, there are no

neighbors on a loopback interface. It is a pseudo-device for assigning local addresses so that the router

can be communicated with by this address, which is always up and can receive traffic from any of the

existing active interfaces. Thus, given reachability from a remote client, the address of the loopback can

be used to communicate with the router through various services such as telnet and SSH. In this way, the

address on a loopback behaves identically to any of the local addresses of the router in terms of the

processing of incoming packets.
