Universal counters
The counters contain details of the number of frames and any errors. The counters are latch and clear
so values indicate the amount of data since the last time the counters were read.
dagconfig –dX –u
(Where X is the device number of the DAG card you want to configure).
For more information see
dagconfig
Example outputs are shown:
Ethernet
Counter
Definition
RX_Bytes
Number of payload bytes received from the line.
RX_Frames
Number of packets received from the line.
RX_FCS
Number of packets received from the line with errors (typically FCS errors).
RX_Protocol_Errors
Number of packets received from the line with errors. Errors can be:
FCS, short packet, truncated packet, length field, length
type, fsame code,
or
fsame invalid errors
.
Port_Drop
Number or packets dropped on the port.
Tx_Bytes
Number of payload bytes transmitted to the line.
Tx_Frames
Number of packets transmitted to the line.
Tx_IF_Drop
(Port 0 or 1). A count of all packets released but not sent on the line.
The packet is discarded when the DAG card is set to NIC mode and no link has
been established.
Tx_ERF_Type_Drop
A count of all Packets in the transferred ERF stream that do not match the
target protocol.
Example:
When the transmit ERF stream contains 10 ETH and 10 POS packets and sends
that on a Ethernet Link only the Ethernet packets will be transmitted. The POS
packets are discarded and counted.
