packets

Rx Unicast

Number of unicast packets received.

 

 

This number does not include packets that

 

 

contain errors.

 

 

 

 

Rx

Number of broadcast and multicast packets

 

NonUnicast

received.

 

 

This number does not include packets that

 

 

contain errors.

 

 

 

 

Tx Unicast

Number of unicast packets transmitted.

 

 

This number does not include packets that

 

 

contain errors.

 

 

 

 

Tx

Number of broadcast and multicast packets

 

NonUnicast

transmitted.

 

 

This number does not include packets that

 

 

contain errors.

 

 

 

receive-errors

Rx Crc

Number of frames received by the port that had

 

 

the correct length but contained an invalid

 

 

frame check sequence (FCS) value. This statistic

 

 

includes frames with misalignment errors.

 

 

 

 

Rx Error

Total number of frames received in which the

 

 

Physical layer (PHY) detected an error.

 

 

 

 

Rx Short

Number of frames received by the port that

 

 

were fewer than 64 bytes long.

 

 

 

 

Rx Overrun

Number of frames received by the port that

 

 

were valid but were longer than 1518 bytes.

 

 

This statistic does not include jumbo packets

 

 

with valid CRCs.

 

 

 

transmit-errors

Tx Crc

Number of frames transmitted by the port that

 

 

had the correct length but contained an invalid

 

 

FCS value.

 

 

 

 

Tx Short

Number of frames transmitted by the port that

 

 

were fewer than 64 bytes long.

 

 

 

 

Tx Fragment

Total number of frames transmitted that were

 

 

less than 64 octets long and had invalid CRCs.

 

 

 

 

Tx Abort

Total number of frames that had a link pointer

 

 

parity error.
