Thanks Ben for the response.
I see that whenever an ovs-vsctl command is issued it seems to go into conf.db
in JSON format as follows.

For each trunk we add, this whole text is getting appended into conf.db and
this is per port. This seems to occupy lot of space onfile system.
Is there a way to avoid this and keep only one instance of the config?

OVS doesn't support ranges here. You can submit a patch to add a new
feature, if you like.
