1206 CHAPTER 94: SFLOW CONFIGURATION
Troubleshooting sFlow
Configuration
The Remote sFlow
Collector Cannot Receive
sFlow Packets
Symptom
The remote sFlow collector cannot receive sFlow packets.
Analysis
■ sFlow is not enabled globally because the sFlow agent or/and the sFlow
collector are not specified.
■ No port 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.
