SMC Networks SMC8150L2 manual Showing Port Statistics

Port Configuration 3

CLI - This example sets the rate limit level for input traffic passing through port 3.

Console(config)#interface ethernet 1/3	4-116
Console(config-if)#rate-limit input 500	4-129
Console(config-if)#

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 3-10 Port Statistics
Parameter	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.
