Port Configuration 3

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.

Description

 

 

Interface Statistics

 

 

 

Received Octets

The total number of octetts 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.

Transmit Multicast Packets

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.

Transmit Broadcast Packets

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.
