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
AAM1212, 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.
Tx jabber This field shows the number of frames transmitted that were longer than 1518
octets (non VLAN) or 1522 octets (VLAN) and contained an incorrect FCS value.
Tx oversize This field shows the number of frames transmitted that were bigger than 1518
octets (non VLAN) or 1522 (VLAN) and contained a valid FCS.
packet(<=64) This field shows the number of frames received and transmitted (including bad
frames) that were 64 octets or less in length (this includes FCS octets but
excludes framing bits).
