No, it doesn't. > but does not delete active meters. Shouldn't meters be deleted as > well. How are you adding meters? The FAQ says: Q: Does Open vSwitch support OpenFlow meters? A: Since version 2.0, Open vSwitch has OpenFlow protocol support for OpenFlow meters. There is no implementation of meters in the Open vSwitch software switch (neither the kernel-based nor userspace switches). > Meters are stored in an array in ofproto where meter_id is used as an index > into the array. > The datapath need to pre-declare the array size using max_meters during a > call to meter_get_features. > This puts a hard limit on the range of Meter IDs 0-max_meters. > It may be very convenient to the controller to have freedom in the selection > of meter_id 32 bits in order to easily associate flows to meters. This is not an Open vSwitch restriction. It comes straight from the OpenFlow specification: "Meters are defined starting with meter_id=1 up to the maximum number of meters that the switch can support." > For example: if the bridge states that max_meters=4 the controller may want > to select meter-ids as a function of vlan: 1000, 1200, 1560, 3420. > Is it possible to change meters in ofproto from an array into hash? Only if you change OpenFlow first. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
