Configuring the Switch
3-122
CLI - This example sets the rate limit for input traffic passing through port 2.
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 EdgeView or HP OpenView.

Table 3-7 Port Statistics
Parameter Description
Interface Statistics
Received Octets The total number of octets received on the interface, including framing
characters.
Received Unicast Packets The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
Received Multicast Packets 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.
Received Broadcast Packets 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.
Received Discarded Packets 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.
Received Unknown Packets The number of packets received via the interface which were
discarded because of an unknown or unsupported protocol.
Received Errors The number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
Transmit Octets The total number of octets transmitted out of the interface, including
framing characters.
