Usage guidelines
A service provider-side port uses the SVLAN TPID to replace the TPID in outgoing frames' SVLAN tags and match incoming tagged frames. An incoming frame is handled as untagged if the TPID in its outer VLAN tag is different from the SVLAN TPID.
Examples
# Set the TPID value in SVLAN tags to 9100 (hexadecimal) on HundredGigE 1/0/1.
