VLAN-VPN inner-cos-trust 

The status of the inner-to-outer tag priority replicating 
feature, enable (enabled) or disable (disabled).  

You can use the vlan-vpn inner-cos-trust command to 
configure the feature. 

VLAN-VPN TPID 

TPID value of the port, which can be configured through 
the vlan-vpn tpid command.

None 

Use the igmp transparent enable command to enable transparent IGMP message transmission on 

the port.  

Use the undo igmp transparent enable command to disable transparent IGMP message transmission 

on the port.  

By default, transparent IGMP message transmission is disabled on a port.  

For a VLAN-VPN-disabled port, the switch can transmit an IGMP message received on the port within 

the VLAN that the IGMP message belongs to normally. For the switch to transparently transmit an IGMP 

message received on a VLAN-VPN port in the outer VLAN, however, you must enable transparent 

IGMP message transmission on the port.  

 

z 

If your switch is required to process the IGMP messages received on a VLAN-VPN port (for 

example, because IGMP or IGMP snooping is enabled on the port), you must disable transparent 

IGMP message transmission on the port so that the switch can process the IGMP messages 

normally. 

z 

Do not enable transparent IGMP message transmission on a port without VLAN-VPN enabled.
