Configuring 802.1q tag-type translation

FIGURE 17 802.1q Tag-type translation configuration example 2

As illustrated in Figure 17, the devices process the packets as follows:

• Path A: When Core Switch 1 receives the tagged packet from Edge Switch 1, it keeps the 8500

tag-type in the frame header (because the incoming port on Core Switch 1 is untagged) and

adds the 9100 tag-type as it sends the packet to the uplink (Core Switch 2). In this case, the

packet is double-tagged as it travels between the core devices.

• Path B: When Core Switch 1 receives the tagged packet from Edge Switch 2, it removes the

8200 tag-type and replaces (translates) it with the 9100 tag-type as it sends the packet to the

uplink (Core Switch 2).

Configuration rules

Configuration of tag-type ports on the Brocade device are on a per-port basis and follow the same

rules as described in “Configuration rules”.
