sFlow Packets Do Not Reach Collector

(1) Checking route to the collector
See "3.6.1 Communication Is Disabled or Is
to check to see if the collector is properly connected to network. If the maximum size of sFlow packets
(max-packet-size) is changed with the configuration, check to see if the connection to the collector can be established
with the specified packet size.
(2) Checking operation status by operation command
Execute the show sflow command several times to display the sFlow statistical information and check to see if
sFlow statistics function operates normally. If the underlined values shown below are not incremented, see
"(3)Checking configuration." If incremented, see
