Comment 2 for bug 1699425

Hi Team,

Since the value of 'Flow Table Full' began to rise, they judged that it reached the limit at 270210 and they unable to generate flow entry beyond the limit 270210 since the value of flow table full is getting increased as below

Flow Table Full 1886

Flow Table Full 1894

After changing the value vr_mpls_labels=11520 vr_flow_entries=1048576 twice in the file /etc/modprobe.d/vrouter.conf, they able to generate the flow entry 437197 which cross the earlier limit 270210. However, this also not getting increased beyond the 437197 since the value of flow table entry is getting increasing as below

Flow Table Full 4507

Flow Table Full 4511

In Build 36, flow was generated up to the upper limit of 500 k flows which is closer to limit set in vr_flow_entries . However, Build 55 and Build 57 did not generate flows up to the upper limit. When they measured in thier lab, it stopped about 300k flow.

They are suspecting that this hold entry has stopped processing the total entry.

Flow Statistics
---------------
     Total Entries --- Total = 297297, new = 0
     Active Entries --- Total = 293200, new = 0
     Hold Entries --- Total = 4097, new = 0 <<<<<<< Here
     Fwd flow Entries - Total = 293200
     drop flow Entries - Total = 0
     NAT flow Entries - Total = 0
