display counters error

Function

The display counters error command displays error packet statistics.

Format

display counters error [ inbound | outbound ] [ interface interface-type [ interface-number ] ]

Parameters

Parameter	Description	Value

Usage Guidelines

You can run the display counters error command to view detailed error packet statistics on all types of interfaces, which facilitates maintenance when there is a large number of error packets. (The actual output information may differ from the following information.)

Example

# Check all error packet statistics on the device.

**Table 1** Description of the **display counters error** command output
Item	Description
Inbound	Inbound error packet statistics.
Outbound	Outbound error packet statistics.
Interface	Interface name.
Total	Total number of inbound and outbound error packets.
CRC	Number of packets with length ranging from 64 bytes to 1518 bytes and incorrect FCS values. For the S5720-HI, S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730-HI, S5730S-EI, S5730-SI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6720S-SI, S6720-SI, S6730-H, S6730S-H, S6730-S, and S6730S-S, the value of this field includes the number of received packets longer than the maximum jumbo frame length and with incorrect FCS values. For switches excluding the S5720-EI, the value of this field contains the number of received packets with length ranging from 1518 bytes to the jumbo frame size configured on the interface and incorrect FCS values. For the S5720-EI whose interfaces are in half duplex mode, the value of this field includes the number of received packets longer than 1518 bytes.
Giants	Number of received packets with length exceeding the maximum jumbo frame size.
Fragments	Number of fragmented packets received by the interface. A fragmented packet is a packet with length less than 64 bytes and incorrect CRC values. On the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-EI, S6720S-EI, S6720S-SI, and S6720-SI, the command output does not contain the Fragments field to display statistics about received fragmented packets.
Runts	Number of received undersized frames with correct CRC values. An undersized frame is a frame that is shorter than 64 bytes, in correct format, and contains a valid CRC field. For the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-EI, S6720S-EI, S6720S-SI, and S6720-SI, the value of this field includes the number of received fragmented packets shorter than 64 bytes and with incorrect CRC values.
DropEvents	Number of received packets that are discarded due to GBP full or back pressure.
Alignments	Number of received frames with alignment error.
Symbols	Number of received frames with coding error.
Collisions	Number of packets with 1 to 15 collisions during packet forwarding. NOTE: If the command output contains only this field and the Excess-Col field is not displayed, the field also includes the number of frames that are canceled due to consecutive 16 collisions.
Excess-Col	After sixteen successive collisions, the system will take it as excessive collision statistics when another collision occurs. Frames that are not sent due to excessive collisions are counted in this field.
Late Collisions	Number of delay collision frames. A delay collision frame is a frame that is delayed because a collision is detected when the first 512 bits of the frame are sent.
