It need transparently transmit the LACP packet when MSTP device interconnect to DataCome or wireless. But mostly the LACP packet cannot transparently transmit using EOS board. The article will tell story.
1.For the transparently transmit board, it use the SD8820 chip, it need disable the function of port detecting, then the LACP can transparently transmit. For example, the board: N2EGT2.
2.For switching processing board, it use the SD8820 chip, it need disable the function of port detecting, then the LACP can transparently transmit. For example, the following board is this kind board: N4EGS4,SSN5EFS0,SSN3EFS4,SSN3EGS2,SSN1EFS0A,SSN1EMS2. And the J5EGS8 board in OSN9500 is also this kind board.
3.The other switching processing board, such as , N4EFS0、N2EFS4、N2EGS2, use the micro-code chip, it can transparently transmit the LACP packet. Due to using different processing chip, processing of LAPC is different for different EOS board.According to different interconnecting condition, we shoul need use different EOS board, and do corresponding configuration to let the LACP can betransparently transmited.
