DESCRIPTION
This field shows the transmission speed of data received on this port in kilobytes per
second.
This field shows the total amount of time the connection has been up.
This field shows the number of good unicast frames transmitted.
This field shows the number of good multicast frames transmitted.
This field shows the number of good broadcast frames transmitted.
Pause is a flow control mechanism that notifies the sender to slow transmission if the
receiver's buffers are (almost) full. This field shows the number of 802.3x Pause frames
transmitted.
You may use commands to request which Pause frames are stopped according to priority (0
to 7). For example, you may request the sender to stop Pause frames with priority equal to
3 and 4. This field shows the number of 802.1Qbb Pause frames transmitted.
This field shows the number of frames with VLAN tags transmitted.
This field shows the number of good unicast frames received.
This field shows the number of good multicast frames received.
This field shows the number of good broadcast frames received.
Pause is a flow control mechanism that notifies the sender to slow transmission if the
receiver's buffers are (almost) full. This field shows the number of 802.3x Pause frames
received.
This field shows the number of 802.1Qbb Pause frames received.
This field shows the number of control frames received (including those with CRC error) but
it does not include the 802.3x Pause frames.
This is a count of successfully transmitted frames for which transmission is inhibited by
exactly one collision.
This is a count of successfully transmitted frames for which transmission was inhibited by
more than one collision.
This is a count of frames for which transmission failed due to excessive collisions. Excessive
collision is defined as the number of maximum collisions before the retransmission count is
reset.
This is the number of times a late collision is detected, that is, after 512 bits of the frames
have already been transmitted.
The following fields display detailed information about frames received that were in error.
This field shows the number of frames received with CRC (Cyclic Redundant Check)
error(s).
This field shows the number of frames received with a length that was out of range.
This field shows the number of frames received that were too short (shorter than 64
octets), including the ones with CRC errors.
