Inner-to-Outer Tag Priority Replicating and Mapping
As shown in Figure 1-2 , the user priority field is the 802.1p priority of the tag. The value of this 3-bit field
is in the range 0 to 7. By configuring inner-to-outer tag priority replicating or mapping for a
VLAN-VPN-enabled port, you can replicate the inner tag priority to the outer tag or assign outer tags of
different priorities to packets according to their inner tag priorities.
Refer to QoS-QoS Profile part for information about priority.
Transparent IGMP Message Transmission on a VLAN-VPN Port
For detailed information about IGMP messages and how a switch processes IGMP messages of
different types, refer to the Multicast module in this manual.
For a VLAN-VPN-disabled port, the switch transparently transmits an IGMP message received on the
port within the VLAN that the IGMP message belongs to. For the switch to transparently transmit an
IGMP message received on a VLAN-VPN port in the outer VLAN, you must enable transparent IGMP
message transmission on the port.
