Function
This command is used to query the statistics of an EPON port. The user can
use the information to detect the current performance of the equipment, identify
and rectify faults timely.
Parameters
| Parameter | Description | Value |
|---|---|---|
| frameid/slotid | Indicates the shelf ID and slot ID of the EPON port to be queried. Enter "/" between the shelf and slot IDs. | Please see Differences Between Shelves. |
| portid | Indicates the ID of the EPON port to be queried. | Please see Differences Between Shelves. |
Usage Guidelines
- The information about different frames of 1G-channel and 10G-channel are displayed only when the queried PON port is in 10G EPON board.
- The function of this command and the display port statistics(epon) command is the same, only the mode is different.
Example
To query the statistics of EPON port 0/3/0 of
10G EPON board, do as follows:
huawei#display port statistics epon
{ frameid/slotid<S><Length 3-15> }:0/3
{ portid<U><0,15> }:0
Command:
display port statistics epon 0/3 0

System Response
- The system displays the queried result when the command runs successfully.
- If the value of an item is 0, it indicates that the port does not receive such type of frames or the port does not have any traffic.
- If a statistical item is not supported, the parameter value is displayed as an en dash (-).
- Information expressed as a percentage the class statistics items accounted for a proportion of the value of all statistics, the actual value after the value is rounded down.
- The percentage in the displayed information is the proportion of the item of the statistics, the displayed value is the actual value rounded down.
- The following table describes the parameters in response to this
command.
Parameter Description Received/Sent bytes Indicates the bytes received or transmitted. Sent multicast bytes Indicates the number of bytes of the transmitted Ethernet multicast frames. Received/Sent frames Indicates the number of frames received or transmitted. Received/Sent unicast frames Indicates the number of unicast frames received or transmitted. Received/Sent multicast frames Indicates the number of multicast frames received or transmitted. Received/Sent broadcast frames Indicates the number of broadcast frames received or transmitted. Received/Sent 64-byte frames Indicates the number of frames with 64 bytes received or transmitted. Received/Sent 65~127-byte frames Indicates the number of frames with 65 to 127 bytes received or transmitted. Received/Sent 128~255-byte frames Indicates the number of frames with 128 to 255 bytes received or transmitted. Received/Sent 256~511-byte frames Indicates the number of frames with 256 to 511 bytes received or transmitted. Received/Sent 512~1023-byte frames Indicates the number of frames with 512 to 1023 bytes received or transmitted. Received/Sent 1024~1518-byte frames Indicates the number of frames with 1024 to 1518 bytes received or transmitted. Received/Sent over 1518-byte frames Indicates the number of frames with more than 1518 bytes received or transmitted. Received/Sent undersized frames Indicates the number of undersized frames received or transmitted.
If the number of received undersized frames exceeds the threshold, the line quality is poor and packet loss occurs.Received/Sent oversize frames Indicates the number of oversized frames received or transmitted.
If the number of received oversized frames exceeds the threshold, the line quality is poor and packet loss occurs.Received/Sent fragments Indicates the number of fragment frames received or transmitted. Received/Sent jabbers Indicates the number of jabber error packets received or transmitted. Received/Sent CRC error frames Indicates the number of cyclic redundancy check (CRC) error frames received or transmitted.
If the number of CRC error frames received increases rapidly, the links between devices may be abnormal, the port negotiation may be incorrect, and a physical fault may occur on the port.Received/Sent error frames Indicates the number of error frames received or transmitted. Received/Sent discarded frames Indicates the number of discarded frames received or transmitted. Received/Sent drop events Indicates the number of discarded events received or transmitted. 1G channel Indicates the 10G channel. The followed displayed statistics of different frames are about 10G channel. 10G channel Received LLID error frames Indicates the number of received LLID error frames. Received ungranted frames Indicates the number of ungranted frames.
