How to "disable" a node in an LTM pool using snmp.

How can I put a node/poolmember in "disabled" mode using snmp ? I mean the mode where persistent connection stay on the node.

 

I found "F5-BIGIP-LOCAL-MIB::ltmNodeAddrMonitorState" and "F5-BIGIP-LOCAL-MIB::ltmPoolMemberSessionStatus", but both set the monitor state and not the node state, which means, the node receives no more connections, even if persistent would tell otherwise.

 

F5-BIGIP-LOCAL-MIB:ltmPoolMemberSessionStatus would be the correct attribute, but it's not writeable!

 

Thanks..
