Interface: GigabitEthernet0/1
Output queue: (Urgent queuing: Size/Length/Discards ) 0/100/0
Output queue: (Protocol queuing: Size/Length/Discards ) 0/500/0
Output queue: (Priorit queuing: PQL 1 Size/Length/Discards)
Top: 3/20/42878 Middle: 10/40/0 Normal: 60/60/259195 Bottom: 80/80/344297

The following commands are configured on the S3610 switch:
qos map-table dotlp-ip
import 1 export4
import 2 export 5
interface Ethernet1/0/8
port link-mode bridge
port link-tpe trunk
port trunk permit vlan 1 4
qos trus t dotlp
interface Ethernet1/0/9
port link-mode bridge
port link-tpe trunk
port trunk permit vlan 1 4
qos gts an cir 65000 cbs 2000000
Then when the traffic is 40Mbps , the packets with the vlan id of 4 and the 802.1p priority are 1 , and the packets with the traffic of 40Mbps with the vlan id of 4 and the 802.1p priority of 2 enter at the same time from port E 1/0/8 , When forwarding from port E1/0/9 , which of the following statements is correct is ____ .( Choose one or more )

• A.portions partial misconfigured
• B.Packet traffic shaping is 65Mbps for forwarding
• C.Packets with 802.1p priority 2 have packet loss on outbound port E1/0/9
• D.Packets with 802.1p priority 1 have packet loss on the outgoing port E1/0/9
• E.80Mbps packets are forwarded normally
• F.All packets with 802.1p priority 1 are stored out of port E1/0/9 and forwarded
• G.All packets with 802.1p priority 2 are forwarded on the outgoing port E1/0/9
