Statistics for TOE Gigabit and TOE 10 Gigabit Ethernet interface

The ifstat command output displays several statistics when you use the command on a TOE gigabit and TOE 10 gigabit Ethernet interface.

RECEIVE section statistics

The following table describes the statistics in the RECEIVE section of the ifstat command output when you use the command on any TOE - 1Gigabit or TOE - 10Gigabit Ethernet interface

Statistic Meaning
Frames/second Rate of received frames per second.
Bytes/second Rate of received bytes per second.
Errors/minute Rate of errors (which led to frames being lost) per minute.
Discards/minute Rate per minute of packets discarded due to unavailable resources.
Total frames Total frames that are received on the interface.
Total bytes Total bytes that are received on the interface.
Total errors Total errors that occur on the interface.
Total discards Total number of packets that were discarded even though no errors were detected. This number is a sum of the "No buffers", "Bus overruns", and "Queue overflows" statistics.
Multi/broadcast Total number of multicast or broadcast packets received.
Alignment errors Number of frames that are both misaligned and contain CRC errors.
Non-primary u/c Number of Ethernet frames received for the partner's MAC address after a failover in a cluster configuration.
Tag drop Number of tagged frames dropped on an interface that is not configured to support VLAN tagging.
Vlan tag drop Number of tagged frames dropped that do not match the VLAN tags configured on the interface.
Vlan untag drop Number of untagged frames dropped on an interface that is configured to be part of a VLAN.
CRC errors Number of packets received with bad CRC.
Runt frames Number of received frames that were less than the minimum size (64 bytes) and had a valid CRC.
Long frames Number of received frames that were greater than the maximum size and had a valid CRC.
Jabber Number of received frames that were greater than the maximum size and had a bad CRC.
No buffer Number of times the driver could not allocate a buffer and a packet was dropped. This might happen when your storage system is very busy. If the count increases continually, it might indicate that a software component is not returning buffers.
Jumbo Number of good packets received that were larger than the standard Ethernet packet size when jumbo frames are enabled.
Pause Frames Number of MAC Control PAUSE frames sent to the link partner to inhibit transmission of data frames for a specified period of time. This can help the partner from overrunning the controller's receive buffers.

TRANSMIT section statistics

The following table describes the statistics in the TRANSMIT section of the ifstat command output when you use the command on any TOE - 1Gigabit or TOE - 10Gigabit Ethernet interface.

Statistic Meaning
Frames/second Rate of transmitted frames per second.
Bytes/second Rate of transmitted bytes per second.
Errors/minute Rate of errors (which led to frames being lost) per minute.
Discards/minute Rate per minute of packets discarded due to unavailable resources.
Total frames Total frames that are transmitted on the interface.
Total bytes Total bytes that are transmitted on the interface.
Total errors Total errors that occur on the interface.
Total discards Total number of packets that were discarded even though no errors were detected. This number is a sum of the "No buffers" and "Queue overflows" statistics.
Multi/broadcast Total number of multicast or broadcast packets transmitted.
No buffers Number of times the driver failed to allocate a buffer for the transmit packet.
Queue overflow Number of outgoing packets dropped because the driver's queue was full. It might indicate a system problem.
Bus Underruns FIFO goes empty before an internal End-Of-Packet indicator is read.
Pause Frames Number of MAC Control PAUSE frames sent to the link partner to inhibit transmission of data frames for a specified period of time. This can help the partner from overrunning the controller's receive buffers.

LINK INFO section statistics

The following table describes the statistics in the LINK INFO section of the ifstat command output when you use the command on anyTOE - 1Gigabit or TOE - 10Gigabit Ethernet interface.

Statistic Meaning
Current state Current state of the interface:
  • up or down—The state of the link.
  • cfg_down—The interface is configured down.
  • enabling—The interface is coming up.
Up to downs Number of times the link toggled between up and down.
Speed Speed of link negotiated or set.
Duplex Duplex of the link negotiated or set.
Flow control The operational flow control setting.
