◆ Tx Errors – The number of UDP datagrams that has failed
transmission.
The most common source of errors is invalid sFlow receiver IP/host
name configuration. To diagnose, paste the receiver’s IP address/host
name into the Ping Web page (Diagnostics > Ping/Ping6).
◆ Flow Samples – The total number of flow samples sent to the sFlow
receiver.
◆ Counter Samples – The total number of counter samples sent to the
sFlow receiver.
Port Statistics
◆ Port – Port identifier.
◆ Rx/TX Flow Samples – The number of flow samples sent to the sFlow
receiver originating from this port. Here, flow samples are divided into
Rx and Tx flow samples, where Rx flow samples contain the number of
packets that were sampled upon reception (ingress) on the port and Tx
flow samples contains the number of packets that were sampled upon
transmission (egress) on the port.
◆ Counter Samples – The total number of counter samples sent to the
sFlow receiver originating from this port.
