Hi! I'm trying to work out whether or not I should use flow-tag to group different customer subnets. I have encountered the following questions from reading the man page:
Multiple actions may match and set tags on the same flow. Note that > listing many actions will cause tags to be applied in O(actions) time. > The actions try to run in O(1) time. For example if 10 prefixes are > listed in a single action it will take about the same CPU as if 100 > prefixes are used. Listing 100 actions will require 100 times the > CPU as 1 action. Does this mean that using flow-tag to tag all you subnets won't give you any performance boost compared to e.g. just filtering your flows per subnet and generating a report of this? Also this example worries me: match 128.146/16 set-destination 0x010001 Does it mean that the destination address will be overwritten? Thanks for reading! All the best, Benjamin
