Rx KB/s
This field shows the transmission speed of data received on this port in kilobytes per
second.
Up Time
This field shows the total amount of time the connection has been up.
Tx Packet
The following fields display detailed information about frames transmitted.
Unicast
This field shows the number of good unicast frames transmitted.
Multicast
This field shows the number of good multicast frames transmitted.
Broadcast
This field shows the number of good broadcast frames transmitted.
Pause
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.
Priority
Pause
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.
Tagged
This field shows the number of frames with VLAN tags transmitted.

Multicast

exactly one collision.
Multiple
This is a count of successfully transmitted frames for which transmission was inhibited by
more than one collision.
Excessive
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.
Late
This is the number of times a late collision is detected, that is, after 512 bits of the frames
have already been transmitted.
Error Packet
The following fields display detailed information about frames received that were in error.
RX CRC
This field shows the number of frames received with CRC (Cyclic Redundant Check)
error(s).
Length
This field shows the number of frames received with a length that was out of range.
