LTM | Disable Pool Member

Hi Team,

 

Hope you all are doing great!

 

Please help me to understand below :-

 

If we disable pool member then will it still send health traffic to backend server or it will not send any traffic to backend member.

 

Regards,

    Hi RAQS,

    If there is a monitor assigned to a pool or pool member, monitor requests are sent to the server, regardless of enable or disable. You can see this with tcpdump.

    tcpdump -ni any host <non-floating-ip> and host <pool-member-ip> and port <pool-member-port>

    When the member is disabled or force-offline, the active connections continue.

    Status Indicator

    ● Black Circle: member disable and available

    ⯁ Black Diamond: member disable and unavailable

    ◼ Black Square: member disable and availability is unknown(no monitor)

    Hi Enes,

     

    Thanks for your reply.. so disabling/enabling and force offline of pool member will still send traffic ?

    If we disable node directly then still health monitor traffic will be send to server ?
