Rx broadcast This field shows the number of good broadcast frames received of 64
to 1518 octets in length (for non VLAN) or 1522 octets (for VLAN),
not including multicast frames. Frames with range or length errors
are also not taken into account.
Rx mac pause This field shows the number of valid IEEE 802.3x Pause frames
received on this port.
Rx fragments This field shows the number of frames received that were less than 64
octets long, and contained an invalid FCS, including non-integral and
integral lengths.
Rx error overrun This field shows how many times an Ethernet transmitter overrun
occurred.
Rx error mru This field shows the number of received frames that were dropped
due to exceeding the Maximum Receive Unit frame size.
Rx dropped This field shows the number of received frames that were received
into the SAM1316-22, but later dropped because of a lack of system
resources.
Rx jabber This field shows the number of frames received that were longer than
1518 octets (non VLAN) or 1522 octets (VLAN) and contained an
invalid FCS, including alignment errors.
Rx error
alignment This field shows the number of frames received that were 64 to 1518
(non VLAN) or 1522 (VLAN) octets long but contained an invalid FCS
and a non-integral number of octets.
Rx oversize This field shows the number of frames received that were bigger than
1518 (non VLAN) or 1522 (VLAN) octets and contained a valid FCS.
Rx undersize This field shows the number of frames received that were less than 64
octets long and contained a valid FCS.
Rx discard This field shows the number of frames dropped based on packet
filtering.
Tx bytes This field shows the number of bytes that have been transmitted on
this port. This includes collisions but not jam signal or preamble/SFD
(Start of Frame Delimiter) bytes.
Tx packets This field shows the number of packets transmitted on this port.
Tx multicast This field shows the number of good multicast frames transmitted on
this port (not including broadcast frames).
Tx broadcast This field shows the number of broadcast frames transmitted on this
port (not including multicast frames).
Tx mac_pause This field shows the number of valid IEEE 802.3x Pause frames
transmitted on this port.
Tx fragments This field shows the number of transmitted frames that were less than
64 octets long, and with an incorrect FCS value.
Tx frames This field shows the number of complete good frames transmitted on
this port.
Tx error underrun This field shows the number of outgoing frames that were less than
64 octets long.
Tx undersize This field shows the number of frames transmitted that were less than
64 octets long and contained a valid FCS.
