Field
Description
Interface
Use the drop-down menu to select the interface for which data is to be displayed or configured. For
non-stacking systems, this field is Slot/Port.
Maximum Frame Size
The maximum Ethernet frame size the interface supports or is configured to support. The maximum
frame size includes the Ethernet header, CRC, and payload.
Packet Lengths Received and Transmitted
section:
64 Octets
The total number of packets (including bad packets) received or transmitted that were 64 octets in
length (excluding framing bits but including FCS octets).
65-127 Octets
The total number of packets (including bad packets) received or transmitted that were between 65
and 127 octets in length inclusive (excluding framing bits but including FCS octets).
128-255 Octets
The total number of packets (including bad packets) received or transmitted that were between 128
and 255 octets in length inclusive (excluding framing bits but including FCS octets).
256-511 Octets
The total number of packets (including bad packets) received or transmitted that were between 256
and 511 octets in length inclusive (excluding framing bits but including FCS octets).
512-1023 Octets
The total number of packets (including bad packets) received or transmitted that were between 512
and 1023 octets in length inclusive (excluding framing bits but including FCS octets).
1024-1518 Octets
The total number of packets (including bad packets) received or transmitted that were between 1024
and 1518 octets in length inclusive (excluding framing bits but including FCS octets).
1519-1522 Octets
The total number of packets (including bad packets) received or transmitted that were between 1519
and 1522 octets in length inclusive (excluding framing bits but including FCS octets).
1523-2047 Octets
The total number of packets (including bad packets) received or transmitted that were between 1523
and 2047 octets in length inclusive (excluding framing bits but including FCS octets).
2048-4095 Octets
The total number of packets (including bad packets) received or transmitted that were between 2048
and 4095 octets in length inclusive (excluding framing bits but including FCS octets).
4096-9216 Octets
The total number of packets (including bad packets) received or transmitted that were between 4096
and 9216 octets in length inclusive (excluding framing bits but including FCS octets).
Basic section:
Unicast Packets
The
Transmit
column shows the total number of packets that higher-level protocols requested be
transmitted to a subnetwork unicast address, including those that were discarded or not sent. The
Receive
column shows the number of subnetwork unicast packets delivered to a higher-layer protocol.
Multicast Packets
The
Transmit
column shows the total number of packets that higher-level protocols requested be
transmitted to a multicast address, including those that were discarded or not sent. The
Receive
column shows the number of multicast packets delivered to a higher-layer protocol.
Broadcast Packets
The
Transmit
column shows the total number of packets that higher-level protocols requested be
transmitted to a broadcast address, including those that were discarded or not sent. The
Receive
column shows the number of broadcast packets delivered to a higher-layer protocol.
Total Packets (Octets)
The total number of octets of data (including those in bad packets) transmitted or received on the
interface (excluding framing bits but including FCS octets). This object can be used as a reasonable
estimate of Ethernet utilization. If greater precision is desired, the etherStatsPkts and etherStatsOctets
objects should be sampled before and after a common interval.
Packets > 1518 Octets
The total number of packets transmitted or received by this interface that were longer than 1518
octets (excluding framing bits, but including FCS octets) and were otherwise well formed. This counter
has a maximum increment rate of 815 counts per sec at 10 Mb/s.
802.3x Pause Frames
The number of MAC Control frames transmitted or received by this interface with an opcode
indicating the PAUSE operation. This counter does not increment when the interface is operating in
half-duplex mode.
FCS Errors
The total number of packets transmitted or received by this interface that had a length (excluding
framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had a bad Frame
Check Sequence (FCS) with an integral number of octets.
Protocol section:
STP BPDUs
The number of Spanning Tree Protocol (STP) Bridge Protocol Data Units (BPDUs) transmitted or
received by the interface.
RSTP BPDUs
The number of Rapid STP BPDUs transmitted or received by the interface.
MSTP BPDUs
The number of Multiple STP BPDUs transmitted or received by the interface.
