thanks for the reply Ben, Some vms are facing packet loss ~40% ,i am trying to understand why its happening,(*lost: *field is 0)
As mentioned in the early mail,*used* counter for both drop action and vlan action is increasing: *in_port(2),*eth(src=00:26:0a:24:b0:00,dst=fe:34:37:a3:fd:9d),eth_type(0x8100),vlan(vid=32,pcp=0),encap(eth_type(0x0800),ipv4(src=109.x.x.111,dst=15.x.x.105,proto=6,tos=0,ttl=56,frag=no),tcp(src=46811,dst=80)), packets:1, bytes:74, u*sed:0.361s*, *actions:*drop *in_port(1),*eth(src=00:26:0a:24:b0:00,dst=fe:34:37:a3:fd:9d),eth_type(0x8100),vlan(vid=32,pcp=0),encap(eth_type(0x0800),ipv4(src=109.x.x.111,dst=15.x.x.105,proto=6,tos=0,ttl=56,frag=no),tcp(src=46811,dst=80)), packets:1, bytes:74, *used:0.359s,* *actions:* pop_vlan,9,5,6,22,11,push_vlan(vid=32,pcp=0),0,pop_vlan,10 These source and destination vms are not on the host where dump-flow has been taken.Can you please suggest some way to fix it.
