Command History
Usage Guidelines The Cisco IOS software automatically enters a directly connected route in the routing table if the
interface is usable. A usable interface is one through which the software can send and receive packets.
If the software determines that an interface is not usable, it removes the directly connected routing entry
from the routing table. Removing the entry allows the software to use dynamic routing protocols to
determine backup routes to the network, if any.
If the interface can provide two-way communication, the line protocol is marked “up.” If the interface
hardware is usable, the interface is marked “up.
If you specify an optional interface type, you see information only on that specific interface.
If you specify no optional arguments, you see information on all the interfaces.
When an asynchronous interface is encapsulated with PPP or Serial Line Internet Protocol (SLIP), IP
fast switching is enabled. The show ip interface command on an asynchronous interface that is
encapsulated with PPP or SLIP displays a message indicating that IP fast switching is enabled.
Examples This example shows how to display the usability status for a specific VLAN:
Switch# show ip interface vlan 1
Vlan1 is up, line protocol is up
Internet address is 10.6.58.4/24
