CLI Reference Guide
Use this command to specify to drop the C-tagged packets that do not match any
VLAN encapsulation pair or remarking pair. Use the no form of this command to
allow the unmatched packet to be forwarded.
None
Disabled
Interface configuration (only available for a UNI port)
If the receiving packet is tagged, the VLAN tunnel table (including VLAN
encapsulation and VLAN remarking) is searched using the packet VLAN ID and
the ingress port. If there is an entry missing, then the packet can optionally be
dropped or have a SP VLAN (service provider VLAN) tag added based on the
VLAN lookup tables (MAC, Subnet, Protocol, Port VLAN ID). When VLAN tunnel
ingress filtering is enabled, the translation missed packets are dropped. If it has
an SP VLAN tag added to the translation missed packet and forwared to the SP
VLAN, it is referred to as VLAN tunnel ingress-checking disabled.
This example shows how to enable the VLAN tunnel ingress-checking Ethernet
