Pool member traffic control
I'm trying to get better control over some pool members. My pool consists of 4 members with a priority grouping. I need to only send traffic to one member at any given time. The F5 seems to want to allow connections to finish first. In this case, I actually don't want that. I want all traffic to the node to stop, immediately.
Is there some parameter I can apply to force the behavior I'm trying to achieve. I need this to happen in an automated fashion.
ltm pool /Common/Priceless-Pool {
members {
/Common/cds80-tcup1:tlisrv {
address 10.0.0.122
monitor /Common/tcup1
priority-group 50
}
/Common/cds81-tcup2:tlisrv {
address 10.0.0.123
monitor /Common/tcup2
priority-group 25
session user-disabled
state user-down
}
/Common/cds82-tcups1:tlisrv {
address 10.0.0.25
monitor /Common/tcups1
priority-group 100
}
/Common/cds83-tcups2:tlisrv {
address 10.0.0.26
monitor /Common/tcups2
priority-group 75
}
}
min-active-members 1
}
- What_Lies_Bene1CirrostratusSet the Pool Action on Service Down setting to Reject.
- R_MarcNimbostratusThat will work for moving down the priority list, but it won't on the way back, unless I mark the active service down at the same time I enable the higher priority member. I guess I can script that, but I was hoping for something automagic. Perhaps an iRule.
- nitassEmployeeThe F5 seems to want to allow connections to finish first. In this case, I actually don't want that. I want all traffic to the node to stop, immediately.i understand there is log when pool member status changes (up/down). is configuring action on log (e.g. tmsh script) helpful?
