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.
