Table 2: Command output

Field	Description
current state	Current physical state of the interface: Administrative DOWN—The interface is shut down with the shutdown command. DOWN—The interface is administratively up but its physical state is down, which may be caused by a connection or link failure. UP—Both the administrative and physical states of the interface are up.
Line protocol current state	Current state of the link layer protocol, which can be: DOWN—The protocol state of the interface is down. UP—The protocol state of the interface is up. UP (spoofing)—The protocol state of the interface pretends to be up. However, no corresponding link is present, or the corresponding link is not present permanently but is established as needed.
Internet Address	IP address of an interface: Primary—Identifies a primary IP address. Sub—Identifies a secondary IP address. unnumbered—Identifies an unnumbered IP address. acquired via DHCP—Identifies an IP address obtained through DHCP. acquired via BOOTP—Identifies an IP address obtained through BOOTP. Cluster—Identifies a cluster IP address. Mad—Identifies a MAD IP address.
Broadcast address	Broadcast address of the subnet attached to an interface.
The Maximum Transmit Unit	Maximum transmission units on the interface, in bytes.
input packets, bytes, multicasts output packets, bytes, multicasts	Unicast packets, bytes, and multicast packets received on an interface (the statistics start at the device startup).
ARP packet input number: Request packet: Reply packet: Unknown packet:	Total number of ARP packets received on the interface (the statistics start at the device startup), including: ARP request packets. ARP reply packets. Unknown packets.
TTL invalid packet number	Number of TTL-invalid packets received on the interface (the statistics start at the device startup).
ICMP packet input number: Echo reply: Unreachable: Source quench: Routing redirect: Echo request: Router advert: Router solicit: Time exceed: IP header bad: Timestamp request: Timestamp reply: Information request: Information reply: Netmask request: Netmask reply: Unknown type:	Total number of ICMP packets received on the interface (the statistics start at the device startup), including: Echo reply packets. Unreachable packets. Source quench packets. Routing redirect packets. Echo request packets. Router advertisement packets. Router solicitation packets. Time exceeded packets. IP header bad packets. Timestamp request packets. Timestamp reply packets. Information request packets. Information reply packets. Netmask request packets. Netmask reply packets. Unknown type packets.
