sFlow Port Information:
Interface CID Interval(s) FID MaxHLen Rate Mode Status
GE1/0/1 2 120 2 128 4000 Random Active
The output shows that GigabitEthernet 1/0/1 enabled with sFlow is active, the counter sampling interval
is 120s, the packet sampling rate is 4000, and that means the sFlow operates normally.
Troubleshooting sFlow configuration
The remote sFlow collector cannot receive sFlow packets
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 switch, 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 switch 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 switch to communicate with the sFlow
collector.
3. Check whether the physical link between the switch and the sFlow collector is normal.
