Ethernet Statistics

Receive/Transmit Statistics
Statistics Type

Description

Total Packets

Received

Unicast Packets

This is the sum for this port of all valid packets received/transmitted as

either Unicast Packets, Broadcast Packets, Multicast Packets or

Ethernet Pause frames.

Broadcast Packets

Multicast Packets

Ethernet Pause Frames

Bytes Received

This is the sum for this port total of all valid bytes received/transmitted

as either Unicast Packets, Broadcast Packets, Multicast Packets or

Ethernet Pause frames.

Total Receive Errors

This is the sum total for this port of all packets received/transmitted in

error as either LAN FCS Errors, Alignment Errors, Undersize,

Fragments, Jabber, Oversize or InDiscard.


Receive/Transmit Performance
Statistics Type

Description

Current Data Rate (kbps)

This is the average for this port of data rate received/transmitted

during the last 1 second.

Avg Data Rate (kbps – 5 minutes)

This is the average for this port of data rate received/transmitted on

this port over the last 5 minutes.

Max Data Rate (since last clear)

This is the maximum received/transmitted data rate this port has

seen since the last time the statistics buffer was cleared.

Current Packets/s

This is the total number of packets received/transmitted on this port

during the last 1 second.

Average Packets/s (5 minutes)

This is the average number of packets received/transmitted per

second on this port over the past 5 minutes.

Max Packets/s (since last clear)

This is the maximum received/transmitted packets per second this

port has seen since the last time the statistics buffer was cleared.

Error Details

All packets received in error are discarded.

Receive Errors
Statistics Type

Description

LAN FCS Error

Indicates a packet was received on his port with an invalid FCS

(sometimes referred to as checksum).

Alignment Error

Indicates a packet was received on this port with an invalid FCS or

was received on a non byte (8 bit) boundary.

Undersize

Indicates that a packet as seen by this port is fewer than 64 octets

long (including FCS octets) but otherwise well formed.

Fragments

Indicates a portion of the packet as seen by this port was received

but one or more sections of the packet are missing.

Jabber

Indicates a device on the network as seen by this port is improperly

handling the Ethernet signaling.

Oversize

Indicates that a packet as seen by this port is larger than 10,240

octets long (including FCS octets) but otherwise well formed.

InDiscards

Indicates that a packet as received by this port that was forwarded

incorrectly or were supposed to be handled in a special manner, but

were not.
