문제1
W has been configured with the following commands in the MSR router:
acl number 2000
rule 0 permit source 192.168.0.0 0.0.0.255
#
traffic classifier 1 operator and
if-match acl 2000
#
traffic behavior 1
car cir 1000 cbs 62500 ebs 0 green pass red discard
#
qos polic test
classifier 1 behavior 1
When the device only needs to enter the interface G0 / 0 network segment 192.168.0.0/24 packets to limit speed of 1Mbps operation.In connection port G0 / 0 following configuration is incorrect.

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
