Service Unavailable Notification???
Guys I have a VIP on :23 with a 3-node pool bound to it. Each node listening on :23.
My question is this, outside of priority group activation, if all 3 servers are down, can the LTM send a service unavailable notification to the client?
Thanks
- hooleylistCirrostratusSomething like this?
when CLIENT_ACCEPTED { if {[active_members [LB::server pool]] < 1}{ TCP::respond "my service down message" } }
- az1441_7592NimbostratusYes!!
Sorry for the noob question..
- hooleylistCirrostratusIt's a relatively simple iRule, but not such a simple question. Glad that works for you.
- az1441_7592Nimbostratushoolio,
- hooleylistCirrostratusI'm not sure what a service down message looks like for telnet. If you need to use binary content in the TCP::respond command, you can follow the steps in SOL7875 and use the binary format command:
- HamishCirrocumulusHmm...
- hooleylistCirrostratusThat's easy enough as LTM will send a reset if no pool members are available. No iRule needed.
