This shows that ______ .

The following commands are configured on the S3610 switch:
qos map-table dot1p-lp
import 1 export 5
interface Ethernet1/0/6
port link-mode bridge
port link-tpe trunk
port trunk permit vlan 1 to 2
qos priori4
interface Ethernet1/0/7
port link-mode bridge
port link-tpe trunk
port trunk permit vlan 1 to 2
qos gts queue 5 cir 12600 cbs 2000000
Then when the flow rate is 10Mbps the vlan id is 2 and 802.1p preferred priority of 1 is the packet from the port E1 / 0/8 into the only port E1 / 0/9 when forwarding.
Then the following statement is correct
