  Note: 

z 

Besides the default TPID 0x8100, you can configure only one TPID value on a Switch 5500-EI 

switch.  

z 

For the Switch 5500-EI series to exchange packets with the public network device properly, you 

should configure the TPID value used by the public network device on both the customer-side port 

and the service provider-side port.  

 

Make sure that the VLAN-VPN feature is enabled on a port before configuring the inner-to-outer tag 

priority replicating and mapping feature.  

Follow these steps to configure the inner-to-outer tag priority replicating and mapping feature: 

Enter system view 

— 

Enter Ethernet port view 

interface interface-type 
interface-number  

— 

Enable the inner-to-outer tag 
priority replicating feature 

Enable the inner-to-outer tag 
priority mapping feature and 
create a priority mapping 

vlan-vpn priority old-priority 
remark new-priority 

Either of the two configurations 
is required. 

By default, neither the 
inner-to-outer tag priority 
replicating feature nor the 
inner-to-outer tag priority 
mapping feature is enabled.  

 

z 

If you have configured the port priority (refer to QoS-QoS Profile Configuration part in this manual), 

you will be prompted that the port priority configured for the current port gets invalid after you 

enable the inner-to-outer tag priority replicating feature. 

z 

The inner-to-outer tag priority replicating feature is mutually exclusive with the inner-to-outer tag 

priority mapping feature.
