Pool Icon Behaivor different if disable from CLI

Pool Status Icon Behavior

 

Hi I was doing some test on a Bigip and came up with the following behavior.

 

Some Basic data: Type: C113 BIG-IP 13.0.0 0.0.1645

 

If i force offline a pool member from the comand line I get a Black diamond. As far as I undersand black diamond (force offline) means no new connections no new persitent connections, only active connections will be allowed to drain from the SRV. (expected behavior)

 

But If I disable the pool member from the command line I get a red Diamond. modify ltm pool DNS-POOL-SRVs members modify { 10.194.111.100:domain { state user-down }}

 

But Red Diamond means no connections at all meaning active connections will be reset it

 

 

Would appreciate any feedback to be clear if this is a normal behavior

    Your CLI command for force offline is wrong. The command you've run is for session disable, which is just disable on the GUI.

    For Forced Offline, please try the below,

    tmsh modify /ltm pool  members modify {  { session user-disabled state user-down} }

    Something like:

    modify ltm pool DNS-POOL-SRVs members modify { 10.194.111.100:domain { session user-disabled state user-down} }

    Do refer for Article for more help.

    to know the command to configure, the bst solution is to show configuration change when you set force-offline in webui.

    to show configuration, use following command:

    list ltm pool

    execute this command with member enabled and forced offline, then compare output.
