| Interface Commands
– 403 –
Excessive Collisions A count of frames for which transmission on a particular interface fails
due to excessive collisions. This counter does not increment when the
interface is operating in full-duplex mode.
Internal MAC Transmit
Errors
A count of frames for which transmission on a particular interface fails
due to an internal MAC sublayer transmit error.
Internal MAC Receive Errors A count of frames that fail reception due to an internal MAC sublayer
receive error.
Frames Too Long A count of frames received on a particular interface that exceed the
maximum permitted frame size.
Pause Frames Input Count of pause frames received on the interface
Pause Frames Output Count of pause frames transmitted from the interface.
RMON Statistics
Octets Total number of octets of data received on the network. This statistic
can be used as a reasonable indication of Ethernet utilization.
Packets The total number of packets (bad, broadcast and multicast) received.
Broadcast Packets The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
Multicast Packets The total number of good packets received that were directed to this
multicast address.
Undersize Packets The total number of packets received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
Oversize Packets The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
Fragments The total number of frames received that were less than 64 octets in
length (excluding framing bits, but including FCS octets) and had either
an FCS or alignment error.
Jabbers The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either an
FCS or alignment error.
CRC Align Errors
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
Packet Size <= 64 Octets The total number of packets (including bad packets) received and
transmitted that were less than 64 octets in length (excluding framing
bits but including FCS octets).
Packet Size 65 to 127 Octets
Packet Size 128 to 255
Octets
Packet Size 256 to 511
Octets
Packet Size 512 to 1023
Octets
Packet Size 1024 to 1518
Octets
The total number of packets (including bad packets) received and
transmitted where the number of octets fall within the specified range
(excluding framing bits but including FCS octets).
