Setting The Link Type Of An Interface - Huawei Quidway S9300 Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - Ethernet
Applicable Environment
To separate the private network from the public network and save VLAN resources, you can
configure double 802.1q tags on a QinQ interface provided by the S9300. The inner VLAN tag
of the private network is distributed for the internal network such as the intranet; the outer VLAN
tag of the public network is distributed for the external network such as the ISP's network. In
this way, a maximum of 4094 x 4094 VLAN tags are provided to enable transparent transmission
of the packets from different private network users with the same VLAN ID.
