Table 31 Port Statistics screen fields (continued)

Field

Description

 

 

128-255 bytes

Received column: Indicates the total number of 128-byte to 255-byte packets

 

received on this port.

 

Transmitted column: Indicates the total number of 128-byte to 255-byte packets

 

transmitted successfully on this port.

 

 

256-511 bytes

Received column: Indicates the total number of 256-byte to 511-byte packets

 

received on this port.

 

Transmitted column: Indicates the total number of 256-byte to 511-byte packets

 

transmitted successfully on this port.

 

 

512-1023 bytes

Received column: Indicates the total number of 512-byte to 1023-byte packets

 

received on this port.

 

Transmitted column: Indicates the total number of 512-byte to 1023-byte packets

 

transmitted successfully on this port.

 

 

1024-1518 bytes

Received column: Indicates the total number of 1024-byte to 1518-byte packets

 

received on this port.

 

Transmitted column: Indicates the total number of 1024-byte to 1518-byte packets

 

transmitted successfully on this port.

 

 

Frame Errors

Indicates the total number of valid-size packets that were received but discarded

 

because of CRC errors and improper framing.

 

 

Undersized Packets

Indicates the total number of packets received on this port with fewer than 64 bytes

 

and with proper CRC and framing (also known as short frames or runts).

 

 

Oversized Packets

Indicates the total number of packets received on this port with more than 1518

 

bytes and with proper CRC and framing (also known as oversized frames).

 

 

Filtered Packets

Indicates the number of packets filtered (not forwarded) by this port.

 

 

Flooded Packets

Indicates the total number of packets flooded (forwarded) through this port

 

because the destination address was not in the address database.

 

 

FCS Errors

Indicates the total number of valid-size packets that were received with proper

 

framing but discarded because of cyclic redundancy check (CRC) errors.

 

 

Collisions

Indicates the total number of collisions detected on this port.

 

 

Single Collisions

Indicates the total number of packets that were transmitted successfully on this

 

port after a single collision.

 

 

Multiple Collisions

Indicates the total number of packets that were transmitted successfully on this

 

port after more than one collision.

 

 

Excessive Collisions

Indicates the total number of packets lost on this port due to excessive collisions.

 

 

Deferred Packets

Indicates the total number of frames that were delayed on the first transmission

 

attempt, but never incurred a collision.

 

 

Late Collisions

Indicates the total number of packet collisions that occurred after a total length of

 

time that exceeded 512 bit-times of packet transmission.
