Rule
You can set 16 different QoS rules. Each QoS rule has its detail setting conditions like:
802.1p,application, DSCP, IP, MAC, Protocol, TOS, VLAN etc, you can modify the default
value to any new one you wish. Please notice that only when the packet fulfill every detail
setting conditions here, then this packet will be remarked as the priority queue of each rule.
The non-selected setting part will be treated as "don't care" and the system will not handle
this setting part. If the original packet does not have 802.1q tagged header, system will not
add header for this packet even the detail setting condition has adding 802.1p priority ability.
