In the MCP 2019.2.4 maintenance update, Mirantis added the possibility
to set and modify the flow_cache_timeout
for OpenContrail vRouter through
the OpenContrail Salt formula.
By default, the timeout value is 180 seconds. The value can be modified
on highly loaded clusters by configuring flow_cache_timeout
in your Reclass model.
To obtain the enhancement, first follow the steps described in Apply maintenance updates.
