Showing Port Statistics

CLI - This example sets the rate limit for input and output traffic passing through 
port 1 to 60 Mbps.
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.

Table 9-4   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.
Transmit Unicast Packets
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.
