Troubleshooting sFlow configuration
The remote sFlow collector cannot receive sFlow packets
Symptom
The remote sFlow collector cannot receive sFlow packets.
Analysis
• The sFlow collector is not specified.
• sFlow is not configured on the interface.
• The IP address of the sFlow collector specified on the sFlow agent is different from that of the remote
sFlow collector.
• No IP address is configured for the Layer 3 interface on the device. Or the IP address is configured,
but the UDP packets that have the IP address as the source cannot reach the sFlow collector.
• The physical link between the device and the sFlow collector fails.
Solution
1. Check that sFlow is correctly configured by using display sflow.
2. Check that a correct IP address is configured for the device to communicate with the sFlow
collector.
3. Check the physical link between the device and the sFlow collector.
