XS712Tv2 can not send a jumbo frame via LAG connection

Hello!!

I am testing a jumbo frame from a Linux PC to another Linux PC via XS712Tv2.

$ ping -M do -s 1474 -c 10 $destinationpc

                                        Linux PC

                                                |

FS_S5850-24S2Q---LAG---XS712Tv2---LAG---Cisco_2960G

                                               |

                                           LAG

                                              |

                                        HP 2510G

Before LAG is enabled on XS712Tv2(Ver.7.0.0.20), everything is fine.

But once LAG is enabled, jumbo frames can not pass the switch.

Whithout XS712Tv2, everythin is fine.

After enabling LAG, jumbo frames can pass all switches

It seems that XS712Tv2 does not support a jumbo frame when LAG is enabled.

At now, I have to connect switches without LAG.

Please let me know if someone has same experience or the way to fix this problem.
