**Table 1** Description of the **display interface vbdif** command output
Item	Description
Vbdif20 current state	Current physical status of the BDIF interface. UP: The physical layer of the interface is enabled. DOWN: The interface is faulty at the physical layer. Administratively down: The administrator has run the shutdown command on the interface.
Line protocol current state	Link protocol status of the BDIF interface. UP: The link protocol of the interface is enabled. DOWN: The interface is faulty at the link protocol layer, or no IP address is specified for the interface.
Last line protocol up time	Time when the protocol status of the BDIF interface became UP the last time. NOTE: This field is displayed only when the protocol state of the interface is UP.
Description	Description of the interface.
Route Port	Layer-3 port.
The Maximum Transmit Unit is	Maximum transmission unit of the interface, which is 1450 bytes by default. A packet longer than the MTU will be fragmented before being forwarded. If fragmentation is prohibited, the packet will be discarded.
Internet Address is	IP addresses of the interface. If no IP address is configured for the interface, the Internet protocol processing: disabled message is displayed.
IP Sending Frames' Format is	Format of Ethernet frames sent by the interface. The default format is PKTFMT_ETHNT_2. When receiving Ethernet frames, the interface can recognize the following frame formats: PKTFMT_ETHNT_2 Ethernet_SNAP 802.2 802.3
Hardware address is	Physical address of the interface.
Current system time	Current system time of the interface.
Last 300 seconds input rate Last 300 seconds output rate	Rates of bits and packets received and sent through the interface in the last 300 seconds. The values (number of bits/300 seconds and number of packets/300 seconds) are updated upon each running of the command.
Input	Number of packets received on the interface. The received packets are classified into the following types: Correct packets, including unicast, broadcast, and multicast packets Error packets Dropped packets Input fields are described as follows: packets and bytes: number of properly received packets and bytes. The packets value equals the sum of unicast, broadcast, and multicast values. unicast, broadcast, and multicast: number of properly received unicast, broadcast, and multicast packets. errors: number of error packets. drops: number of discarded packets.
Output	Number of packets sent from the interface. The sent packets are classified into the following types: Correct packets, including unicast, broadcast, and multicast packets Error packets Dropped packets Output fields are described as follows: packets and bytes: number of properly sent packets and bytes. The packets value equals the sum of unicast, broadcast, and multicast values. unicast, broadcast, and multicast: number of properly sent unicast, broadcast, and multicast packets. errors: number of error packets. drops: number of packets that cannot be sent
Last 300 seconds input utility rate	Ratio of the packet receiving rate to the total bandwidth. If the value is --, the BDIF interface does not support packet rate statistics.
Last 300 seconds output utility rate	Ratio of the packet sending rate to the total bandwidth. If the value is --, the BDIF interface does not support packet rate statistics.
