The ifstat command output displays several statistics when you use the command on the BGE 10/100/1000 Ethernet interface.
The following table describes the statistics in the RECEIVE section of the ifstat command output when you use the command on the BGE 10/100/1000 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. |
Fragment | Number of received frames that were less than the minimum size and had a bad 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. |
Xon | Number of XON frames received when receive or full flow control is enabled. |
Xoff | Number of XOFF frames received when receive or full flow control is enabled. |
Jumbo | Number of good packets received that were larger than the standard Ethernet packet size when jumbo frames are enabled. |
Ring full | Not used. Ignore. |
Jumbo error | Error detected while processing a jumbo packet. Packet is discarded. |
The following table describes the statistics in the TRANSMIT section of the ifstat command output when you use the command on the BGE 10/100/1000 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. |
Max collisions | Number of frames that were not transmitted because they encountered the maximum number of allowed collisions. Only valid in half-duplex mode. |
Single collision | Number of frames that encountered exactly one collision. Only valid in half-duplex mode. |
Multi collisions | Number of frames that encountered more than one collision, but less than the maximum allowed. Only valid in half-duplex mode. |
Late collisions | Number of collisions that occurred outside the collision window. Only valid in half-duplex mode. |
Xon | Number of XON frames transmitted when send or full flow control is enabled. |
Xoff | Number of XOFF frames transmitted when send or full flow control is enabled. |
Jumbo | Number of packets transmitted that were larger than the standard Ethernet packet size when jumbo frames are enabled. |
Deferred | Number of frames for which the first transmission was delayed because the medium was busy. |
MAC Internal | Number of frames not transmitted due to an internal MAC sublayer error. |
The following table describes the statistics in the LINK INFO section of the ifstat command output when you use the command on the BGE 10/100/1000 Ethernet interface.
