Description

The total number of octets received on the interface, including framing

characters.

The number of subnetwork-unicast packets delivered to a higher-layer

protocol.

The number of packets, delivered by this sub-layer to a higher (sub-)layer,

which were addressed to a multicast address at this sub-layer.

The number of packets, delivered by this sub-layer to a higher (sub-)layer,

which were addressed to a broadcast address at this sub-layer.

The number of inbound packets which were chosen to be discarded even

though no errors had been detected to prevent their being deliverable to a

higher-layer protocol. One possible reason for discarding such a packet

could be to free up buffer space.

The number of packets received via the interface which were discarded

because of an unknown or unsupported protocol.

The number of inbound packets that contained errors preventing them

from being deliverable to a higher-layer protocol.

The total number of octets transmitted out of the interface, including

framing characters.

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 total number of packets that higher-level protocols requested be

transmitted, and which were addressed to a multicast address at this

sub-layer, including those that were discarded or not sent.

The total number of packets that higher-level protocols requested be

transmitted, and which were addressed to a broadcast address at this

sub-layer, including those that were discarded or not sent.

Showing Port Statistics

You can display standard statistics on network traffic from the Interfaces Group and
Ethernet-like MIBs, as well as a detailed breakdown of traffic based on the RMON
MIB. Interfaces and Ethernet-like statistics display errors on the traffic passing
through each port. This information can be used to identify potential problems with
the switch (such as a faulty port or unusually heavy loading). RMON statistics
provide access to a broad range of statistics, including a total count of different
frame types and sizes passing through each port. All values displayed have been
accumulated since the last system reboot, and are shown as counts per second.
Statistics are refreshed every 60 seconds by default.

Note:

RMON groups 2, 3 and 9 can only be accessed using SNMP management
software such as HP OpenView.
