icontrol for removing VLAN's from VS once the VS goes down

Hi Guys,

 

 

I hope you are all well, I have a little scenario that I'm having trouble with.

 

 

We have a health monitor setup to monitor tcp/61619 and this HM is applied to a Pool which is then applied to a Virtual Server.

 

 

When the HM fails (i.e. i stop the listening port on the node) the VS still listens on tcp/61619 and I understand that the only way to stop the VS from listening is to remove it from the VLAN.

 

 

I'm thinking that I could use icontrol to run a script and remove the VS from the specific VLAN.

 

 

Can someone please advise if this is possible? the script would need to be triggered once the VS goes down.

 

 

Thanks,

 

JT

    It is possible. You could pass snmp traps to a system to listen for pool down message, then use icontrol to move the virtual server into a dummy inaccessible vlan until the pool is back up. Have you tried an iRule that discards requests in the event the pool is down? 

    
when CLIENT_ACCEPTED {
  if { [active_members my_pool] < 1 } {
    discard
  }
}
