display this interface
Function
The display this interface command displays interface information in the current interface view.
Usage Guidelines
In the interface view, you can run the display this interface command to rapidly view the status of the interface and packet statistics on the interface.
Although the default level of the display this interface command is monitoring level, this command must be run in the interface view. Therefore, to run this command, you need to be of the configuration level or higher.
Example
# Display information about GE0/0/1.

Description |
Interface description. |
PVID |
Default VLAN ID of the interface. |
TPID |
Type of frames that are supported on the interface. By default, this field displays 0x8100, indicating an 802.1Q frame. If the device does not support 802.1Q frames, the interface discards the 802.1Q frames immediately after receiving them. This field is displayed only for a Layer 2 interface. |
The Maximum Frame Length |
Maximum frame length allowed by the interface. |
IP Sending Frames' Format |
Format of the frame contained in the sent IP packet, which can be PKTFMT_ETHNT_2, Ethernet_802.3, or Ethernet_SNAP. |
Hardware address |
MAC address of the device. |
Last physical up time |
Last time the interface went Up physically. If this field displays "-", the physical status of the interface does not change. |
Last physical down time |
Last time the interface went Down physically. If this field displays "-", the physical status of the interface does not change. |
Current system time |
Current system time. If the time zone is configured and the daylight saving time is used, the time is in YYYY/MM/DD HH:MM:SS UTC±HH:MM DST format. |
Port Mode |
Working mode of the interface:
|
Speed |
Current rate of an interface. |
Loopback |
Loopback configuration of the interface. |
Duplex |
Duplex mode of the interface. |
Negotiation |
Auto-negotiation mode of the interface. |
Mdi |
Network cable type of the interface. |
Last 300 seconds input rate |
Incoming packet rate (bits per second and packets per second) within the last 300 seconds. |
Last 300 seconds output rate |
Outgoing packet rate (bits per second and packets per second) within the last 300 seconds. |
Input peak rate 0 bits/sec,Record time |
Maximum rate of incoming packets and time when the maximum rate is reached. |
Output peak rate 0 bits/sec,Record time |
Maximum rate of outgoing packets and time when the maximum rate is reached. |
Input |

Broadcast |
Number of broadcast packets received or sent by the interface. |
Jumbo |
Number of jumbo frames received or sent by the interface. |
Discard |
Number of packets discarded by the interface during physical layer detection. |
Total Error |
Number of error packets found during physical layer detection. |
CRC |
Number of CRC error packets received by the interface. |
Giants |
Number of jumbo frames with correct FCS received by the interface. |
Jabbers |
Number of jumbo frames with incorrect FCS received by the interface, including alignment errors (the number of bytes that a packet contains is not an integer). |
Throttles |
Number of undersized frames with incorrect FCS received by the interface. |
Runts |
Number of undersized frames with correct FCS received by the interface. |
Alignments |
Number of received frames with alignment errors. |
Symbols |
Number of received frames with coding errors. |
Ignoreds |
Number of received MAC control frames with OpCode not being PAUSE. |
Frames |
Number of packets with incorrect 802.3 length. |
Collisions |
Number of sent packets with 1 to 15 conflict events. |
ExcessiveCollisions |
Number of packets with 16 conflict events and failing to be sent. |
Late Collisions |
Number of packets with conflict and delayed. |
Deferreds |
