Configuring 802.1q tag-type translation
11
Figure 28
shows a basic example application of the 802.1q tag-type translation feature.
FIGURE 28
802.1q tag-type translation configuration example 1
As illustrated in
Figure 28
, the devices process the packet as follows:
•
Customer Edge Switch 1 sends a packet with an 802.1q tag-type of 8100 to Provider Core
Switch 1.
•
Since the customer-facing interface on Provider Core Switch 1 has the same 802.1q tag-type
as the incoming packet, it removes the 8100 tag-type and replaces (translates) it with the
9100 tag-type as it sends the packet to the uplink (Provider Core Switch 2).
•
The same process occurs between Provider Core Switch 2 and Customer Edge Switch 2.
Figure 28
shows a simple application of the 802.1q tag-type translation in which all of the ports are
tagged and the tag-types between devices match. In this example, each device performs the
802.1q tag-type translation as the packet traverses the network.
