This read-write object sets the priority value stamped on DoS-attack packets as they're forwarded to the configured mirror port, with 8 meaning the packet's original priority is left unchanged. Admins use it to mark mirrored attack traffic with a distinct priority so it can be queued or filtered separately from normal mirrored traffic, but a valid mirror port must already be specified before this value takes effect. For example, setting swDoSCtrlMirrorPriority to 7 tags mirrored attack packets with the highest priority so a downstream analyzer can easily separate them from lower-priority mirrored traffic.
