Method and apparatus providing network communications between devices using frames with multiple formats

摘要: A method and an apparatus providing data communications among network devices using tagged untagged frame formats. In one embodiment, a virtual local area (VLAN) is implemented frames that may be transferred in both the are switches format, independent of whether source sent or format. addition, destination receive either originally send Cyclic redundancy check (CRC) code information contained as left unchanged when VLAN, even though have been modified prior to transfer switches. New CRC generated for reformatted containing outbound ports such with valid codes forwarded devices. event switch receives corrupt from device, corresponding device switch.
