5.9 Selective Q-in-Q
This function allows to assign external SPVLAN (Service Provider's VLAN), substitute Customer
VLAN, and block the transmission of traffic based on configured filtering rules by internal VLAN numbers
(Customer VLAN).
The list of rules will be created for the device, that will be used for traffic processing.
The Selective-Q-in-Q rule configuration commands are not available in the acl-only mode.
If at least one Selective Q-in-Q rule is present for an interface, broadcast storm logging
becomes disabled for this interface.
