, 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”
