[Mainline-Build 2704]: UI- changing protocol based flow aging timeout to 0 deletes the entry from agent

[alok kumar]

steps-
1. configure flow aging as below, it gets saved as expected and same is reflected is agent introspect.
Protocol: TCP, Port: 10000, Timeout: 10 seconds
2. now change the above entry timeout value to 0 and save. UI shows the configuration with timeout 0, but from agent actually it gets deleted.

similar issue is observed while adding new entry with timeout 0, it gets saved in UI but could not see this entry in agent.

[Biswajit Mandal (bmandal)]

UI sends correct data and it is reflected in API Server also,

I set 0 from UI and I see the value is set properly,
{"flow_aging_timeout": [{"timeout_in_seconds": 0, "protocol": "tcp", "port": 678}]},

And whole dump for global-vrouter-config

I see below config in agent introspect in ifmap_agent.xml but it's not configured:

flow-aging-timeout protocol:udp port:2222 timeout-in-seconds:0

complete global vrouter config from ifmap in agent introspect:

adding vrouter tag to have a look.

[Hari Prasad Killi (haripk)]

Value 0 is invalid for timeout and hence agent ignores the configuration. A syslog message can be generated to indicate the same.

Reducing the severity as this is invalid configuration and nothing untoward is happening.
