3.15.1sFlow Packets Do Not Reach Collector

(1)Checking route to the collector

See "3.6.1 Communication Is Disabled or Is Disconnected" and "3.9.1 Communication Is Disabled or Is Disconnected" 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 "3.6.1 Communication Is Disabled or Is Disconnected," "

3.9.1Communication Is Disabled or Is Disconnected" and "(5)Checking settings of collector" to check to see if the collector is properly connected to network.
