z The IP address of the sFlow collector specified on the sFlow agent is different from that of the
remote sFlow collector.
z No IP address is configured for the Layer 3 interface on the device, or the IP address is
configured, but the UDP packets with the IP address being the source cannot reach the sFlow
collector.
z The physical link between the device and the sFlow collector fails.
Solution
1) Check whether sFlow is correctly configured by displaying sFlow configuration with the display
sflow command.
2) Check whether the correct IP address is configured for the device to communicate with the sFlow
collector.
3) Check whether the physical link between the device and the sFlow collector is normal.
