How to 'Forced Offline' on a pool member using tmsh.

I interact with the f5 via perl scripts using tmsh when pulling members in and out of the pool.

 

 

What is the tmsh command line command to 'Forced Offline' on a pool member? Below is my one liner just to disable pool members. Please show me, TIA.

 

 

tmsh modify ltm pool POOL members modify { 172.16.70.66:xxxx 172.16.70.68:xxxx 172.16.70.70:xxxx 172.16.70.72:xxx { state up session disabled } }

    From the reference manual, session disabled and session enabled are your only options. I just tested using "state down" instead, and that appears to represent "Forced Offline."

    Thanks Chris. Will 'state down' allow the existing transactions to gracefully disconnect or will this sever the connection?

    Forced offline finishes off current connections.

    I think the only time LTM will reset existing connections is if the pool member is marked down by a monitor and the pool option for 'action on service down' is reject. You could also delete the connection table entry and then LTM should send a reset on the next packet it receives.

     

     

    The online help for the node page shows these options:

     

     

    Enabled (All traffic allowed)

     

    Disabled (Only persistent or active connections allowed)

     

    Forced Offline (Only active connections allowed)
