Configuring The Inner-To-Outer Tag Priority Replicating And Mapping Feature; Displaying And Maintaining Vlan-Vpn Configuration - 3Com 4500 Configuration Manual

Besides the default TPID 0x8100, you can configure only one TPID value on a Switch 4500
switch.
For the Switch 4500 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.

Configuring the Inner-to-Outer Tag Priority Replicating and Mapping Feature

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:
To do...
Enter system view
Enter Ethernet port view
Enable the inner-to-outer tag
priority replicating feature
Enable the inner-to-outer tag
priority mapping feature and
create a priority mapping
If you have configured the port priority (refer to QoS 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.
The inner-to-outer tag priority replicating feature is mutually exclusive with the inner-to-outer tag
priority mapping feature.
