**Table 1** Description of the **display interface vbdif** command output
Item	Description
Vbdif20 current state	Physical status of a VBDIF interface. UP: The physical status of the interface is Up. DOWN: The physical status of the interface is Down. Administratively down: The administrator has run the shutdown command on the VBDIF interface.
Line protocol current state	Link-layer protocol status of a VBDIF interface. UP: The link-layer protocol of the interface is Up. DOWN: The link-layer protocol of the interface is Down, or no IP address is assigned to the interface.
Last line protocol up time	Last time the link-layer protocol of an interface goes Up. NOTE: This field is displayed only when the link-layer protocol status is Up.
Description	Description of a VBDIF interface. The description helps you learn the functions of the interface.
Route Port	Layer 3 interface.
The Maximum Transmit Unit is	Maximum transmit unit (MTU) of an interface. The default MTU is 1500 bytes. Packets whose size is greater than the MTU are fragmented before being transmitted. If non-fragmentation is configured, these packets are discarded.
Internet Address is	IP address of an interface. If no IP address is configured for the current interface, the command output is displayed as "Internet protocol processing: disabled."
IP Sending Frames' Format is	Format of the Ethernet frames sent by a VBDIF interface. The default value is PKTFMT_ETHNT_2. A VBDIF interface can identify the received Ethernet frames of the following formats: PKTFMT_ETHNT_2 Ethernet_SNAP 802.2 802.3
Hardware address is	Physical address of an interface.
Current system time	System time.
Input	Number of packets received by the interface.
Output	Number of packets sent by the interface
