When QinQ is enabled on the switch all S-VLAN member ports must be categorized as either
port-type customer-network or
provider-network (See an example below).
Figure 61: Customer or provider ports in the provider network
All ports of a QinQ-enabled device default to
provider-network. Any ports participating in the provider bridge used to connect to customer equipment must be manually configured as port-type
customer-network. In a mixed mode device, ports that are members of C-VLANs and that do not participate in the provider-bridge cannot be configured to any port-type.
The following command allows you to configure the appropriate port-type.
Syntax:
no interface {[port-list] | Trkx} qinq port-type {customer-network | provider-network}
Configures the specified ports/trunks as a customer network port or provider network port.
