Run the following command:
rule 5 permit 8100 ffff 16
//Set rule5. In this rule, if the next two bytes of a packet offsetting by 16 bytes are 8100,
two tags are contained in the packet and the packet is transmitted.

Run the following command:
rule 10 permit 0a ff 19
//Set rule10. In this rule, if the inner VLAN ID of a packet is 10, the packet is transmitted.

Run the following command:

//According to the rule in acl 5000, change the priority of the outer CoS to 6 and deliver it
to port 0/3/0 of the LSW in the incoming direction.
Combine the preceding ACL rules. The rule after translation is: If packets sent from port
0/3/0 have two tags and the inner VLAN ID is 10, change the CoS priority of the outer
VLAN of the packets to 6.
Suggestions and
Summary:
If QinQ streams on the MA5680T need to be filtered or matched, the user-defined ACL
must be used. The standard or extended ACL does not take effect on the QinQ stream.

site. The optical path is normal. Replace one of the ONUs that get online and offline
frequently. The fault persists. The ONU after replacement and other ONUs still get online
and offline frequently.
