OSLAM-8G Port Double Tag ======================== Ingress Double Tag 2 - The ingressing frames are examined to see if they contain 802.3ac tag with the IEEE standard EtherType of 0x8100 or if they contain a tag with an EtherType defined in oslam8gCoreTag. The oslam8gCoreTag will be used if this port's oslam8gPortUseCoreTag is used. If the frames do contain the expected tag, the tag is removed (and the CRC is recomputed). Essentially, untagged frames remain untagged, single tagged frames become untagged and double tagged frames become single tagged. These now single tagged frames will be considered tagged only if its EtherType value is 0x8100 no matter what the EtherType value was found on the removed tag. No padding is performed so a tagged frame must be at least 68bytes in size or it will be discarded. 1 - Tagged frames are not modified when received. The Tag data that is removed from the frame can be ignored (i.e., the frame is treated as if the removed tag never existed) or the removed Tag data can be used for switching and priority decisions (i.e., the removed Tag's VID and PRI bits are internally assigned to the frame). The action that is taken is controlled by the oslam8gUseDoubleTagData
