--: Does not agree with the IP flow detecting condition because it is not the IP packet.

*1: This function can specify the priority of all IP packets by flow configuration definition.

*2: The output priority indicates the queue number for stacking packets.

*3: GR2000-2S and GR2000-4S in which RP-A1, RP-C, and RP-D are installed has the same priority level as when it mismatches the flow detection conditions because IPv6 QOS is not supported.
