我只有三個需求:
(1)我希望保障ETH3(Port3)的QoS優先權最高足以擠掉ETH1(Port1)
(2)ETH1的QoS限制上傳200Mbps以下或保證ETH3可以擠掉它
(3)ETH2接MOD TV不會斷線
目前的想法很混亂，不知怎麼理清頭緒:

我想先建立vlan 設定port貼VLAN TAG

再到Add Network Traffic Class Rule設定
Class Interface:ETH1
Ether Type:IP(0x800)
Source MAC Address:填上連接ETH1 PC的MAC
Source IP Address:填上連接ETH1 PC的IP
Source Subnet Mask:填上連接ETH1 PC的Mask
Destination IP Address: 留白
Destination Subnet Mask:留白
Differentiated Service Code Point (DSCP) Check: 63
Protocol:留白
Assign Classification Queue:ppp0_3@Prec1&Path0&PtmPriLo
Mark Differentiated Service Code Point (DSCP):63
Mark 802.1p priority:7
Tag VLAN ID:剛剛ETH1指派設定的VLAN TAG

最後再去QoS -- Queue Management Configuration設定
Configure default 802.1q vlan and 802.1p中的
802.1q VLAN ID [1-4095]:剛才的VLAN
Mark 802.1p priority:7
Tag VLAN ID:剛才的VLAN TAG
請高手協助!感恩~
