sFlow Port Information:
Interface CID Interval(s) FID MaxHLen Rate Mode Status
Eth1/0/1 2 120 2 128 4000 Random Active
The output shows that Ethernet 1/0/1 enabled with sFlow is active, the counter sampling interval is 120
seconds, the Flow sampling interval is 4000, all of which indicate sFlow operates normally.
Troubleshooting sFlow configuration
Symptom
The remote sFlow collector cannot receive sFlow packets.
Analysis
•
The sFlow collector has no IP address specified.
•
No interface is enabled with sFlow to sample data.
•
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 with the IP address being the source cannot reach the sFlow collector.
•
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.
