There is no Virtual address as GTM pool member to choose

Hi,

 

I run in to problem with creating pool member on GTM. My GTM device has been connected to other LTM devices successfully and iQuery session has been established entirely, But when i decided to add some VIP as pool members, nothing found on this list!

 

iqdump command shows that GTM is obtaining VIP information but i don't why nothing is being presented at VIP list.

Could please help me in this regard?
