[ovs-dev] Unable to hit group table entry

[Ning Wu]

Hi All,

I want to add some flow rules with actions as a group entry. The group and
flow rule have been installed successfully. Outputs below are obtained by
the ovs-ofctl command dump-flows, dump-groups and dump-group-stats.
According to the stats for the flow, the flow rule was hit, but the group
stats showed packet_count=0, and the actions for the group was not executed.

The ovs-vswtichd log did not give me any error though. I am wondering what
would be the potential reasons for this issue.

-- flow entry
cookie=0x2d00008226e53b, duration=57.152s, table=2, n_packets=38,
n_bytes=3724, send_flow_rem priority=100,ip,nw_dst=10.0.2.0/24
actions=group:5

-- group entry
group_id=5,type=select,bucket=actions=dec_mpls_ttl,set_field:00:00:00:00:01:80->eth_src,set_field:00:00:03:00:33:80->eth_dst,output:3

-- group stats
group_id=5,duration=60.242s,ref_count=1,packet_count=0,byte_count=0,bucket0:packet_count=0,byte_count=0

Thanks in advance!
