[Edgecore SONiC] Selective QinQ Follow

QinQ is a feature designed for service providers who carry traffic of multiple customers across their networks and are required to maintain the VLAN and Layer 2 protocol configurations of each customer without impacting the traffic of other customers. The SPVLAN (Service Provider VLAN) tags will be inserted in the customer frames when they enter the service provider network, and the tags will be stripped after they leave the service provider network.

• Switch model name:

  AS7726-32X, AS7326-56X, AS7816-64X, AS5835-54X(T), AS4630-54PE

• Edgecore SONiC version:

  • Edgecore-SONiC_20201123_130028_ec202006_74

  • Edgecore-SONiC_20201229_070315_ec202006_101

• Doesn’t support QinQ for CLI.

Step 1. Down speed to 1G on Ethernet0 and Ethernet1 on AS5835-54X.(refer to Switch port attributes)

Step 2. Created the VLAN and allowed the VLAN member as topology.(refer to VLAN & inter-VLAN routing)

Step 3. Save those setting to config_db.json.

admin@sonic:~$ sudo config save -y

Step 4. Modified the /etc/sonic/config_db.json

AS5835-54X:

admin@sonic:~$ sudo vi /etc/sonic/config_db.json
{
    omitted...
    "VLAN_STACKING": {
        "Ethernet0|ingress|10": {
            "action": "push",
            "s_vlanid": "100"
        },
        "Ethernet0|egress|100": {
        "action": "pop"
        }
    }
}

AS4630-54PE:

admin@sonic:~$ sudo vi /etc/sonic/config_db.json
{
    "VLAN_STACKING": {
        "Ethernet0|ingress|10": {
            "action": "push",
            "s_vlanid": "100"
        },
        "Ethernet0|egress|100": {
        "action": "pop"
        }
    }
}

Step 5. Reload services to apply QinQ setting.

admin@sonic:~$ sudo config reload -y

Capture packet on AS4630-54PE’s Ethernet1.
