CAUTION:
•
Perform the configuration on ports (of switches in the service provider network) with customer networks
connected to them. H3C recommends that you configure the qinq ethernet-type command and the qinq
enable command on the same card.
• The qinq ethernet-type command must be used with the qinq enable command.
• A card supports only one TPID value in addition to its default TPID.
To set the TPID value in VLAN tags:
Step Command Remarks
