LAG Min-link feature

Hello,

I am testing the LAG minimum link functionality and its seems to have wrong behavior.

My setup has LAG of 3 links, when i shutdown 2 link, the LAG is down, but traffic still passing through remaining link.

Setup :

admin@CSW1:~$ show interfaces portchannel
Flags: A - active, I - inactive, Up - up, Dw - Down, N/A - not available,
       S - selected, D - deselected, * - not synced
  No.  Team Dev      Protocol     Ports                          Oper Key  Admin Key    Fast Rate
-----  ------------  -----------  ---------------------------  ----------  -----------  -----------
    1  PortChannel1  LACP(A)(Dw)  Ethernet8(D) Ethernet12(D)           11  auto         false
                                  Ethernet16(S)

admin@CSW2:~$ show interfaces portchannel
Flags: A - active, I - inactive, Up - up, Dw - Down, N/A - not available,
       S - selected, D - deselected, * - not synced
  No.  Team Dev      Protocol     Ports                          Oper Key  Admin Key    Fast Rate
-----  ------------  -----------  ---------------------------  ----------  -----------  -----------
    1  PortChannel1  LACP(A)(Dw)  Ethernet16(S) Ethernet8(D)           11  auto         false
                                  Ethernet12(D)

configuration :
sudo config portchannel add PortChannel1 --min-links=2
 },
    "PORTCHANNEL": {
        "PortChannel1": {
            "admin_status": "up",
            "fast_rate": "false",
            "lacp_key": "auto",
            "min_links": "2",
            "mtu": "9100"
        }
