We checked the switch logs and came up with the below analysis:

A total of 4 PG are created, port Group information :

         PG_ID      PG_Members    PG_Name    PG_Mode

         ----------------------------------------------------------------------------------------

         0       1;5;6;7;8       pg0     -

The port16~19 map to port3:

Thu Oct 29 01:11:42 2015         admin, console, ag --mapadd 1 "0;9;10;11"

Thu Oct 29 01:11:54 2015         admin, console, ag --mapadd 2 "12;13;14;15"

Thu Oct 29 01:12:04 2015         admin, console, ag --mapadd 3 "16;17;18;19"

Thu Oct 29 01:12:14 2015         admin, console, ag --mapadd 4 "20;21;22;23"


we found that the port3 doesnt have fiber inside:

   3   3   010300   id    N16    No_Light    FC 

            

 

Solution

we have  configure all of the external port into the same PG, in this condition, all the ports will be backup for each other, you can connect fiber to anyone port.

 We have removed the maping and   PORT group and remap 

# remove the map

ag --mapdel 3 "16;17;18;19"

ag --mapdel 4 "20;21;22;23"

ag --mapdel 2 "12;13;14;15"

 

# remove the PG

ag --pgremove 2

ag --pgremove 3

ag --pgremove 1

 

# re-map it

ag --mapadd 2 "12;13;14;15"

ag --mapadd 1 "16;17;18;19"

ag --mapadd 2 "20;21;22;23"
