Nimbostratuspriority groups and priority group activation
Hi, newbie here. I have a VS setup with 1 pool, that has 4 members. 2 members are set in a priority group with no.10, the other 2 in priority group with no.5. Priority group activation is set to Less...
Hi Nate,
Looking at your requirements, failing from PG10 to PG5 is completely achievable using PGA.
Your latter requirement isn't possible using standard configuration.
The only achievable way you could do that with 1 Pool, was if your application/server was capable of listening on multiple ports, and you could have PG10 with your preferred members, and then cascade down through orders of preference combinations based on other PG statements.... But this would get messy ! It hurts my head even thinking about it!
Another way would be to use a fallback pool on the Virtual Server, and if PGA members for PG10 and 5 are down. Use the fallback pool...

NimbostratusHI Iain,
Yeah, that's what I figured. Currently testing PGA with destination address persistence, which could potentially give most of the requirement. Will let you know how it turns out.
