I''m considering using tcng for compiling a set of HTB bandwidth allocations, which may change now and then, due to new users, etc. There may be a simple web front-end to change the allocations. All allocations are done by subnets, no complicated rules involving matching on ports. My questions are: 1. Is there any disruption to the running HTB if a new set of actions is loaded, after deleting the current set with the first line of tc qdisc del dev eth0X root 2. If there is a disruption, it is possible to postprocess the generated actions so that only subtrees are affected. I''m thinking of a simple approach of grepping for the various handles and sending the outputs to various files where they will be compared with the previous output and the file is not loaded if there has been no change.
