Table 2 Interface Status Indicators

Events that can affect the status of interfaces:
If you hot-insert a device (not power down the unit first), it appears in the lists of interfaces
immediately (after a page refresh) on the configuration pages.
If you hot-pull a device, and no configuration exists for it, it disappears from the lists of
interfaces immediately.
If you hot-pull a device, and it had a configuration, its configuration details continue to be
displayed and can be changed even after a reboot.
Hotswapped interfaces that are fully seated in a router's chassis are represented in the
ifTable (MIB-II), ipsoCardTable (IP440-IPSO-System-MIB), and the hrNetworkTable
(Host-Resources-MIB).
Unwanted configurations of absent devices can be deleted, which removes the physical and
logical interfaces from all interface lists.
Configuring Tunnel Interfaces
Tunnel interfaces are used to encapsulate protocols inside IP packets. Use tunneling to:
Send network protocols over IP networks that don't support them.
Encapsulate and encrypt private data to send over a public IP network.
Create a tunnel logical interface by specifying an encapsulation type. Use Network Voyager to
set the encapsulation type. Network Voyager supports two encapsulation types, DVMRP and
GRE.
The tunnel logical interface name has the form:
tun0c<chan>

The physical interface is enabled, but the device does not detect a connection to the
network.
The physical interface is ready for use. It is enabled and connected to the network.
