GTM SNMP gtmPoolMbrIp doesn't work on v11.4

I have been using SNMP to get the list of memberIPs on GTM pool. It doesn't work on 11.4 but on earlier versions work. With the comments , It says deprecated.. 1) even its deprecated .. it should return the IP which is not happening 2) I looked the MIB and none of them seems to return the LBmember IP.

Any hints will help ?
