Troubleshooting Sflow Configuration; Symptom; Analysis - HP 5500 EI Series Configuration Manual

3. Configure flow sampling:
# Set the Flow sampling mode and sampling interval.
[Device-GigabitEthernet1/0/1] sflow sampling-mode random
[Device-GigabitEthernet1/0/1] sflow sampling-rate 4000
# Specify sFlow collector 2 for flow sampling.
[Device-GigabitEthernet1/0/1] sflow flow collector 2
# Display the sFlow configuration and operation information.

The output shows that GigabitEthernet 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.
