LevelOne GSW-2600TXM manual Displaying Ethernet Port Statistics, Parameter Description

3.7.1.1.Displaying Ethernet Port Statistics

Port Statistics display key statistics from the Interfaces Group and Ethernet-like MIBs for each port. Error statistics on the traffic passing through each port are displayed. This information can be used to identify potential problems with the switch, such as a faulty port or unusually heavy loading. The values displayed have accumulated since the last system reboot.

Select the required port. The statistics displayed are indicated in the following figure and table.

Parameter	Description
Interfaces Group
In Octets	The total number of octets received on the interface, including
	framing characters.
In Unicast Pkts.	The number of subnetwork-unicast packets delivered to a
	higher-layer protocol.
In Non-Unicast	The number of non-unicast (that is, subnetwork- broadcast or
Pkts.	subnetwork-multicast) packets delivered to a higher-layer protocol.
In Discards	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.
In Errors	The number of inbound packets that contained errors preventing
	them from being deliverable to a higher-layer protocol.
Alignment Errors	The number of alignment errors (missynchronized data packets).
