sflow not sending data

Hi all,

I have configured sflow but the collector is not seeing any data

Here is my config am I missing something?

-NEXUS-CORE1#
-NEXUS-CORE1# show sflow
sflow sampling-rate : 50000
sflow max-sampled-size : 200
sflow counter-poll-interval : 100

sflow collector-ip : 10.1.0.170 , vrf : default
sflow collector-port : 2055

Anyone?

It might be a routing issue.

Dropped Datagrams : 91245

sflow collector-ip : 10.1.0.170 , vrf : default

vrf default... that is the global VRF

If you are sourcing the SFLOW from the mgmtX interface the VRF should be set to "management"

VRF source is important. The destination needs to be reachable from that source VRF. 



have you verified with any type of packet capture between the source and destination... are sflow packets leaving the source switch?
